DESCRIPTION OF EMBODIMENTS
[0021] Embodiments will now be described by reference to the drawings.
(1) Overview of Embodiments
[0022] An ultrasonic diagnosis apparatus according to an embodiment comprises a determining unit, a selecting unit, and a transfer unit. The determining unit determines, based on operation condition setting information selected prior to an ultrasonic examination, an image attribute of an image obtained in the ultrasonic examination. The selecting unit selects, from among a plurality of servers, a transfer destination server assigned a server attribute suitable for the image attribute. The transfer unit transfers the image to the transfer destination server.
[0023] According to the above-described configuration, a transfer destination server suitable for a transfer target image is selected automatically at the time of image transfer. The transfer target image is then transferred to that transfer destination server. Since it is unnecessary for the examiner to select a transfer destination at the time of image transfer, the examiner's workload can be reduced, and incorrect selection of a transfer destination server can be avoided.
[0024] When an ultrasonic examination is to be performed, prior to the ultrasonic examination, operation conditions of the ultrasonic diagnosis apparatus are set. More specifically, operation conditions appropriate for the area of examination (i.e., the field of clinical practice, the tissue to be examined, or the like) are set. With that as background, in the above-described configuration, an image attribute is determined based on operation condition setting information. The operation condition setting information includes preset data, operation conditions specifically set for the ultrasonic diagnosis apparatus, and the like.
[0025] In an ultrasonic diagnosis apparatus, a plurality of sets of preset data are generally provided. Each set of preset data includes parameters that define operation conditions of the ultrasonic diagnosis apparatus. A selected specific set of preset data is used as the operation condition setting information. The image attribute is determined based on that specific set of preset data.
[0026] Typically, one or a plurality of sets of preset data are provided for each individual area of examination. A set of preset data customized by an examiner may also be used. In any case, when an ultrasonic examination is to be performed, a specific set of preset data appropriate for that ultrasonic examination is selected manually or automatically. The selected specific set of preset data is information associated with a specific area of examination or information that indicates a specific area of examination. On the basis of this information, the image attribute is determined. In an embodiment, the image attribute corresponds to a category into which the image is classified. The server attribute corresponds to a category into which the server is classified.
[0027] In an embodiment, the ultrasonic diagnosis apparatus includes a storage unit having stored therein preset data management information for managing areas of examination for which the respective sets of preset data are used. Based on the preset data management information, the determining unit determines, as the image attribute, an area of examination for which a specific set of preset data is used. The preset data management information is, for example, information constituting a preset data management table. Information identifying an area of examination may be included in each set of preset data.
[0028] In an embodiment, the storage unit stores therein server management information for managing, as the server attribute, one or a plurality of areas of examination assigned to each server. The selecting unit identifies the transfer destination server based on the server management information. The server management information is, for example, information constituting a server management table.
[0029] In an embodiment, the storage unit stores therein image management information for managing image attributes of respective images that have been obtained and stored in an ultrasonic examination. When a transfer target image is designated from among the stored images, the selecting unit selects a transfer destination server based on the image management information and the server management information. The image management information is information included in an image management table. To each image, information for management thereof may be added.
[0030] In an embodiment, a secondary image is generated by performing processing with respect to a primary image which is an image obtained in an ultrasonic examination. When the secondary image is designated as the transfer target image, the selecting unit selects, from among a first server assigned a server attribute suitable for the image attribute of the primary image and a second server for storing secondary images, one or both of the first server and the second server as the transfer destination server. According to this configuration, the examiner's workload can be reduced also at the time of transfer of secondary images. A secondary image is an image that is derivatively generated as a result of a processing of a primary image. This processing includes measurement, analysis, three-dimensional image formation, and the like.
[0031] In an embodiment, when a training image attribute is additionally assigned to a transfer target image, the selecting unit selects, as the transfer destination server, both of a first server assigned a server attribute suitable for the image attribute of the transfer target image and a second server for storing training images. According to this configuration, transfer and accumulation of images for training use are facilitated. Designation of the training image attribute may be performed by the examiner, or may be performed automatically based on a result of image analysis.
[0032] An ultrasound image transfer method according to an embodiment includes a determining step, a selecting step, and a transfer step. In the determining step, an image attribute of an image obtained in an ultrasonic examination is determined based on operation condition setting information selected prior to the ultrasonic examination. In the selecting step, a transfer destination server assigned a server attribute suitable for the image attribute is selected from among a plurality of servers. In the transfer step, the image is transferred to the transfer destination server.
[0033] The above-described ultrasound image transfer method is implemented as a hardware function or a software function. A program for carrying out the above-described ultrasound image transfer method may be installed into an information processing device via a network or a portable recording medium. The concept of the information processing device encompasses an ultrasonic diagnosis apparatus, an ultrasonic diagnosis system, a computer, and the like. The information processing device comprises a non-transitory storage medium.
(2) Details of Embodiments
[0034]
[0035] The ultrasonic diagnosis apparatus 10 is connected to a network 12 provided within the medical institution. In the network 12, N (number) servers are connected, including a server (server A) 14, a server (server B) 16, and a server (server N) 18. Further, in the network 12, another ultrasonic diagnosis apparatus 20 is also connected. The entirety or a part of the network 12 may be the Internet.
[0036] Each server 14, 16, 18 is a file server into which images obtained by the ultrasonic diagnosis apparatuses 10, 20 are uploaded. For example, images that are designated as targets of image interpretation are downloaded from the servers 14, 16, 18 to a computer used for image interpretation. To each server 14, 16, 18, a specific area of examination is assigned as a server attribute. A plurality of specific areas of examination may be assigned to each individual server 14, 16, 18. An area of examination is a concept corresponding to a field of clinical practice, an examined body part, or the like. Typically, for each area of examination, a different ultrasonic examination is performed.
[0037] The ultrasonic diagnosis apparatus 10 will now be described in detail. A probe (ultrasound probe) 22 is a device that performs transmission of ultrasound and reception of reflected waves. In the probe 22, a transducer array composed of a plurality of transducers is provided. By means of the transducer array, an ultrasound beam is formed and electronically scanned. As electronic scan methods, an electronic linear scan method, an electronic sector scan method, and the like are known. A two-dimensional transducer array may be provided in the probe 22.
[0038] At the time of transmission, a transmission/reception unit 24 supplies a plurality of transmission signals in parallel to the transducer array, and a transmission beam is thereby formed. At the time of reception, when reflected waves from the interior of a living body are received at the transducer array, a plurality of reception signals are output in parallel from the transducer array to the transmission/reception unit 24. In the transmission/reception unit 24, the reception signals are subjected to phase alignment and summing (i.e., delay and summing), and reception beam data are thereby generated.
[0039] By performing an electronic scan of the ultrasound beam, a plurality of sets of reception beam data located serially along the electronic scan direction are obtained. Those sets of reception beam data constitute reception frame data. By repeating the electronic scan, a plurality of sets of reception frame data are generated, and those sets of reception frame data are sequentially output to an image forming unit 26.
[0040] The image forming unit 26 is a device that generates sets of display frame data from the sets of reception frame data. Specifically, the image forming unit 26 is a device that forms tomographic images which are ultrasound images, and is composed of a digital scan converter; namely, an exclusive processor. The image forming unit 26 has functions such as a coordinate conversion function, a pixel interpolation function, and a frame rate conversion function.
[0041] In the configuration example shown in drawing, the sets of display frame data are transmitted to a display unit 29 via a control unit 28. On the display unit 29, the tomographic images are displayed as a moving image. The displayed moving image is stored in response to a manipulation for storing performed by the examiner. Alternatively, a still image selected from among a plurality of still images constituting the moving image is stored in response to a manipulation for storing performed by the examiner.
[0042] The control unit 28 is composed of a processor that executes programs, and is specifically composed of a CPU. Operations of the constituent elements of the ultrasonic diagnosis apparatus 10 are controlled by the control unit 28.
[0043] Before performing an ultrasonic examination, operation conditions are set. Specifically, based on a specific set of preset data that is selected by the examiner or selected automatically, the control unit 28 sets operation conditions of the ultrasonic diagnosis apparatus. The operation conditions include the operation mode, electronic scan method, depth of diagnosis, transmission frequency, transmission power, reception gain, display conditions, display format, and the like. A set of preset data is a group of parameters that define the operation conditions.
[0044] To the control unit 28, a control panel 30 is connected, and a communication unit 31 is also connected. The communication unit 31 is connected to the network 12. The control unit 28 exchanges data with other apparatuses via the communication unit 31 and the network 12. The control panel 30 is an input device comprising switches, buttons, a keyboard, a trackball, and the like. The display unit 29 is composed of a liquid crystal display, an organic EL display, or the like.
[0045] In an embodiment, the control unit 28 has a transfer control function. This function is expressed as a transfer control unit 32 in
[0046] To the control unit 28, a first storage unit 34 and a second storage unit 36 are connected. Each of the first storage unit 34 and the second storage unit 36 is composed of a semiconductor memory, a hard disk, or the like. A single storage unit may constitute the first storage unit 34 and the second storage unit 36.
[0047] The first storage unit 34 has stored therein a preset data management table 38, an image management table 40, and a server management table 42. Further, a preset data group 44 is stored in the first storage unit 34.
[0048] The preset data group 44 is composed of sets of preset data 44a that are selectively used. In accordance with an ultrasonic examination that is to be performed, a specific set of preset data 44a is selected from the preset data group 44 and used. Specifically, based on the selected specific set of preset data 44a, the operation conditions of the ultrasonic diagnosis apparatus 10 are set. With that done, the ultrasonic examination is started. For performing various ultrasonic examinations, a large number of sets of preset data 44a are provided. Each set of preset data 44a is associated with an area of examination.
[0049] The preset data management table 38 is a table for managing the sets of preset data 44a, and contains preset data management information. In an embodiment, the preset data management table 38 contains information identifying an area of examination for which each set of preset data 44a is used. The information identifying an area of examination may be included in each set of preset data 44a.
[0050] The image management table 40 is a table for managing an image attribute and the like for each stored image. The image management table 40 contains image management information. In an embodiment, as an image attribute, an area of examination is managed. Specifically, when an image (i.e., a still image or moving image) is stored during execution of an ultrasonic examination, the area of examination associated with the set of preset data being used in the current ultrasonic examination is registered as the image attribute of that image.
[0051] The server management table 42 is a table for managing a server attribute and the like for each server. The server management table 42 contains server management information. In an embodiment, as a server attribute, an area of examination is managed. In other words, one or a plurality of areas of examination are assigned in advance to each server, and the one or plurality of areas of examination are managed as the server attribute.
[0052] The second storage unit 36 stores ultrasound images 46 that were designated as targets of storage. From among these images, a specific ultrasound image or a specific group of ultrasound images are designated as the target of transfer by the examiner. Transfer target images may be designated automatically.
[0053] The ultrasound images 46 may include various images such as tomographic images, color flow mapping images, and three-dimensional images. In an embodiment, the images are transferred using the DICOM (Digital Imaging and Communications in Medicine) protocol, which is an international standard protocol, or the like.
[0054] In
[0055] When an image designated by the examiner is to be stored, the image attribute determining unit 50 determines the image attribute of that image. Specifically, the image attribute determining unit 50 refers to the preset data management table, and identifies the area of examination associated with the currently-used set of preset data. Subsequently, the image attribute determining unit 50 determines the identified area of examination as the image attribute of the image obtained in the current ultrasonic examination. The image attribute registering unit 52 registers the determined image attribute in the image management table 40. In an embodiment, since the image attribute is determined and registered at the time of storing of images, the image attribute of a transfer target image can be identified instantly at the time of image transfer. However, the image attribute may alternatively be determined at the time of image transfer.
[0056] When a transfer target image is designated, the transfer destination selecting unit 54 refers to the image management table, and identifies the image attribute of the transfer target image. Subsequently, the transfer destination selecting unit 54 refers to the server management table so as to identify a server assigned a server attribute suitable for the image attribute of the transfer target image, and selects that server as a transfer destination server. Specifically, the transfer destination selecting unit 54 selects, as the transfer destination server, a server that satisfies the condition of selection that the area of examination is the same. The transfer unit 56 transfers the transfer target image to the transfer destination server.
[0057] When the server attribute suitable for the image attribute is assigned to a plurality of servers, the transfer target image is transferred to those servers in parallel. The examiner is only required to designate or select the transfer target image, and does not need to select the transfer destination server for the transfer target image. The selection of the transfer destination server is performed automatically by the transfer control unit 32. Accordingly, the examiner's workload at the time of image transfer can be reduced significantly, and each transfer target image can be correctly transferred to its appropriate transfer destination server.
[0058] The transfer target image may be designated automatically. Further, before executing a transfer, information regarding the transfer destination server may be displayed on the display unit. In that case, the image may be actually transferred when a confirming input is received from the examiner.
[0059] The transfer result managing unit 58 serves to manage, for each image transfer, the result of the transfer; namely, a success or failure of the transfer. Specifically, transfer successes and failures are managed for each transfer destination server.

[0061]
[0062]
[0063]
[0064]
[0065] The window 100 contains a list 102 of areas of examination and checkboxes 104. By manipulating the checkboxes 104, server attributes are designated. When it is desired to assign all areas of examination, a special checkbox 106 is manipulated. The window 108 has a configuration identical to that of the window 100. As indicated by reference numeral 110, a plurality of areas of examination are selected simultaneously.
[0066] Next, operations and controls performed by the transfer control unit will now be described by reference to
[0067] In
[0068] In
[0069] As described above, in the ultrasonic diagnosis apparatus according to an embodiment, a transfer destination server suitable for the transfer target image is selected, and the transfer target image is transferred to that transfer destination server. Accordingly, the examiner is not required to designate or select a transfer destination at the time of image transfer. As a result, the examiner's workload can be reduced, and incorrect selection of a transfer destination server can be avoided.
[0070] During an ultrasonic examination, at a point when an image is stored, that image may be automatically transferred. After completion of an ultrasonic examination, at each time a transfer target image is designated from among a stored group of images, the designated image may be transferred. After completion of an ultrasonic examination, a stored group of images may be automatically sorted and transferred. On each day of examination, after completion of the last ultrasonic examination, the entirety or a part of a group of images stored on that day of examination may be automatically sorted and transferred. When a transfer of a certain image results in a failure, at a point after elapse of a predetermined time therefrom, that image may be automatically retransferred. A screen for setting or selecting a transfer schedule may be provided to the examiner.
[0071]
[0072] In
[0073] When a stored image (i.e., a primary image) is reproduced and subjected to a measurement or analysis, the measurement result or analysis result is reflected in the image. The image having the result reflected therein is a secondary image. A secondary image contains information (such as graphics and numerical values) that are not included in a primary image. A secondary image is an image derived from a primary image, and is, for example, an image including a result of measurement or analysis of the primary image. A three-dimensional image generated from a plurality of primary images may serve as a secondary image. A secondary image is stored in response to a manipulation for storing performed by the examiner or stored automatically.
[0074] Based on the secondary image flag 116, whether or not the stored image is a secondary image (i.e., whether or not the image has the secondary image attribute) can be identified. When a stored image is designated as a training image by the examiner, a training image attribute is assigned to that image. Based on the training image flag 118, whether or not the image is a training image can be identified.
[0075] In
[0076] Subsequently, the transfer control unit 32A refers to the server management table 42, and selects, as a transfer destination server, a server assigned the server attribute suitable for the image attribute of the transfer target image. Apart from this selection, when the transfer target image is a secondary image, the secondary image storing server 120 is selected as a transfer destination server. Further, when the transfer target image is a training image, the training image storing server 122 is selected as a transfer destination server. After that, the transfer control unit 32A transfers the transfer target image to the selected one or plurality of transfer destination servers.
[0077] Accordingly, when a secondary image is designated as a transfer target image, that image is transferred to the secondary image storing server 120. Further, when a training image is designated as a transfer target image, that image is transferred to the training image storing server 122. When a primary image has already been transferred and a secondary image corresponding to that primary image is designated as a transfer target image, that secondary image may be transferred to only the secondary image storing server 120.
[0078] In an embodiment, the servers to be designated as transfer destination servers are information processing devices that are physically independent from each other. However, each of those servers may alternatively be a logical server. A computer used for image interpretation or a specific folder located therein may be designated as a transfer destination server. A recording medium (including a USB memory) may be designated as a transfer destination.
[0079] In the above-described embodiment, instead of the area of examination, a different attribute may be designated as the image attribute and the server attribute. Examples of the different attribute include the operation mode, image category, name of disease (or symptom), and the like. While the preset data management table, the image management table, and the server management table are provided in the above-described embodiment, the preset data management information, the image management information, and the server management information may be managed by another method.
