DETAILED DESCRIPTION OF EMBODIMENTS

[0024] FIG. 1 schematically illustrates a system 100 including an imaging system 102, such as a CT scanner, and a computing system 104 configured at least as a dedicated review station and also referred to herein as the dedicated review station (DRS) and the dedicated review station computing system.

[0025] The imaging system 102 includes a generally stationary gantry 106 and a rotating gantry 108, which is rotatably supported by the stationary gantry 106 and rotates around an examination region 110 about a z-axis. A radiation source 112, such as an x-ray tube, is rotatably supported by the rotating gantry 108, rotates with the rotating gantry 108, and emits radiation that traverses the examination region 110. A radiation sensitive detector array 114 subtends an angular arc opposite the radiation source 112 across the examination region 110. The radiation sensitive detector array 114 detects radiation traversing the examination region 110 and generates a signal indicative thereof for each detected photon.

[0026] A reconstructor 116 reconstructs the projection data, generating volumetric image data indicative of a scanned portion of a subject or object located in the examination region 110. A general-purpose computing system 104 or computer serves as an operator console. The console 118 includes a human readable output device such as a monitor and an input device such as a keyboard, mouse, etc. Software resident on the console 118 allows the operator to interact with and/or operate the scanner 100 via a graphical user interface (GUI) or otherwise. A subject support 120, such as a couch, supports an object or subject in the examination region 110 before, during and/or after scanning

[0027] The dedicated review station 104 includes a communication interface 122, a human readable output device such as a display monitor(s) 124 and an input device(s) 126 such as a keyboard, mouse, a touch screen, etc. The dedicated review station 104 further includes one or more computer processors 128 (e.g., a central processing unit or CPU, a microprocessor, etc.) and computer readable storage medium 130, which excludes transitory medium, such as physical memory, a memory device, and/or other non-transitory storage medium. The computer readable storage medium 130 includes one or more computer readable instructions 132. The one or more computer processors 128 are configured to the execute at least one of the one or more computer readable instructions 132 and/or instructions carried by a carrier wave, a signal and/or other transitory medium.

[0028] The illustrated computer readable instructions 132 include at least a dedicated review station instruction 134. When executed, the dedicated review station 104 is referred to as a dedicated review station 104. Briefly turning to FIG. 2, in one instance the dedicated review station instruction 134 includes a graphical user interface instruction 202, a view port instruction 204, and a visualization instruction 206. As described in greater detail below, the graphical user interface instruction 202 is configured to render a graphical user interface (GUI) in a single display monitor 124 or different GUIs receptively in different display monitors 124, the view port instruction 204 is configured to render a single view port in each GUI or multiple view ports in each GUI, and the visualization instruction 206 is configured to provide visualization tools (e.g., algorithms) for each view port.

[0029] With reference to FIGS. 1 and 2, the dedicated review station 104 receives volumetric image data automatically from the imaging system 102 (and/or other imaging system) as the imaging system 102 acquires data and generates the volumetric image data during a scan. This data is referred to as real-time data herein at least since the data is transferred and available as soon the data is generated. As described in greater detail below, the real-time data can be automatically transferred via a channel 136, which may include a healthcare facility/imaging center network and/or other computer network, and/or a dedicated and/or direct connection there between, without an intermediate system such as a PACS and/or otherwise having to run a software application, select an image file, e.g. The system 100 can be pre-configured to transfer all or less than all of the images.

[0030] In one instance, the dedicated review station 104 provides immediate access to the received images. Immediate, as used here, refers to as soon as the dedicated review station 104 receives an image. For instance, if a scanned series contains 1000 images being transferred (which can take several dozens of seconds, depending on reconstruction speed), the user can start scrolling through a subset of what has been already received, and once new images arrive, the scroll operation covers more and more images. Additionally or alternatively, the dedicated review station 104 allows, concurrently and independently, different personnel to visualize (including manipulate) the same or different anatomy from these images. This may allow multiple diagnoses and/or decisions to be made simultaneously. Furthermore, the dedicated review station 104 mitigates interruption of workflow as the console 118 can be used to plan and/or scan patients independent of any visualization at the dedicated review station 104.

[0031] Turning to FIG. 3, an example of the (computing system) dedicated review station 104 is schematically illustrated. In this example, the dedicated review station 104 includes a computer 300 configured as a desktop 308 and including a wireless keyboard 310, a single display monitor 124, and multiple pointing devices 1261, 1262 and 1263. The computer 300 could alternatively be a tower, a workstation, a laptop, a tablet, and/or other computer. An example operating system that supports multiple pointing devices is Windows operating system, a product of Microsoft, a company headquartered in Wash., USA. Additionally or alternatively, the dedicated review station 104 includes multiple device drivers which support the multiple pointing devices 1261, 1262 and 1263.

[0032] Executing the dedicated review station instruction 134 causes the processor 128 to display of a single graphical user interface 302 in the single display monitor 124. The graphical user interface 302 includes separate view ports 304.sub.1, 304.sub.2 and 304.sub.3, each configured to display a single image 306.sub.1, 306.sub.2 and 306.sub.3, and each controlled with a wireless mouse pointing device 126.sub.1, 126.sub.2 and 126.sub.3. In a variation, at least one of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 can be wired and/or another type of pointing device such as a track ball, a touchpad, a digital pen, etc. Likewise, the keyboard can alternatively be wired. Furthermore, in other embodiments, the graphical user interface 302 includes more or less view ports (e.g., only one, two, or more than three), and the dedicated review station 104 includes more or less pointing devices input devices 126.

[0033] Each of the view ports 304.sub.1, 304.sub.2 and 304.sub.3 includes its own set of visualization from the visualization instruction 206. For example, each view port independently allows display of a different or same image selected one of the received images, relative to the image(s) displayed in another of the view port(s). Furthermore, each view port includes one or more of the following visualization tools, which can be set independent of another view port: image slice thickness, filter (e.g., bone vs soft tissue), CT number range and center (window/level), slice orientation (e.g., axial, coronal, sagittal and/or oblique), rendering (e.g., 3D (surface, volume, etc.), 4-D, maximum-intensity projection (MIP), minimum-intensity projection, etc.), contrast, brightness, color, segmentation, zoom, pan, rotate, scroll, etc. These actions are not only independent from another view port, but they can also be performed concurrently while performing any of these acts in the other view port.

[0034] In one instance, at least one of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 can be configured to operate with more than one of the view ports 304.sub.1, 304.sub.2 and 304.sub.3. In this configuration, in one example, the multiple pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 each can be used with each of the view ports 304.sub.1, 304.sub.2 and 304.sub.3. For example, the pointing device 126.sub.1 can be used to open an image in the view ports 304.sub.1 and 304.sub.3, the pointing device 126.sub.2 can be used to set the slice thickness in both of the view ports 304.sub.1 and 304.sub.3, and the pointing device 126.sub.3 can be used to point, alternatively, in any one of the view port 304.sub.1, 304.sub.2 and 304.sub.3. In a variation, each of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 is dedicated to a single one of the view ports 304.sub.1, 304.sub.2 and 304.sub.3. FIG. 3 shows a first pointer 312 in the view port 304.sub.1 controlled by the pointing devices 126.sub.1, and a second different pointer 314 in the view port 304.sub.2 controlled by the pointing devices 126.sub.1, which can be used simultaneously or serially. It is to be understood that the size and shape of the first pointer 312 and the second pointer 314 is for explanatory purposes and is not limiting.

[0035] FIG. 4 schematically illustrates a variation of the configuration described in connection with FIG. 3 in which the display monitor 124 includes multiple display monitors 124.sub.1, 124.sub.2, and 124.sub.3, each respectively including its own GUI 302.sub.1, 302.sub.2, and 302.sub.3, each respectively with its own one of the view ports 304.sub.1, 304.sub.2 and 304.sub.3, each respectively displaying one of the images 306.sub.1, 306.sub.2 and 306.sub.3. In a variation, the dedicated review station 104 includes more or less monitors 124. In another variation, at least one of the monitors 124.sub.1, 124.sub.2, and 124.sub.3 includes a GUI with more than one view port, such as a configuration combining the configurations described in FIGS. 3 and 4.

[0036] With FIGS. 3 and/or 4, in one instance, at least two of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 can be operated simultaneously or serially respectively by different users. This includes a first user operating one of the at least two of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 simultaneously with another user operating a different one of the at least two of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3. The simultaneous operation can be in a same view port and/or different view ports. In another instance, one or more of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 can be operated simultaneously or serially by a single user. This includes simultaneously operating more than one of the pointing devices 126.sub.1, 126.sub.2 and 126.sub.3 in a same view port and/or different view ports.

[0037] FIG. 5 schematically illustrates an example in which the dedicated review station 104, the reconstructor 116 and the console 118 are located in a control room 502, and a remainder 506 (components 102-114) of the imaging system 102 (REMAINDER IM SYSTEM) are located in an examination room 504, which is a separate and distinct room relative to the control room 502. In this example, the examination room 504 is the room in which a patient is scanned and includes a material in the walls, etc., which absorbs, blocks, attenuates, etc. radiation, mitigating radiation from leaving the examination room 504. It is to be understood that the size and shape of the rooms 502 and 504 are for illustrative purposes and is not limiting. Generally, the rooms 502 and 504 are next to each other with a lead glass and/or other window there between.

[0038] FIG. 6 schematically illustrates a variation in which the reconstructor 116 and the console 118 are located in the control room 502, and the remainder 506 of the imaging system 102 and the dedicated review station 104 are located in the examination room 504.

[0039] FIG. 7 schematically illustrates another variation in which the reconstructor 116 and the console 118 are located in the control room 502, the remainder 506 of the imaging system 102 is located in the examination room 504, and the dedicated review station 104 is located in another or viewing room 702, which is a separate and distinct room relative to the control room 502 and the examination room 504. In FIG. 7, the viewing room 702 is remote from the rooms 502 and 504. In a variation, the viewing room 702 can share a wall(s) with one or both of the rooms 502 and 504.

[0040] FIGS. 8, 9 and 10 schematically illustrate examples of the communication channel 136 between the imaging system 102 and the dedicated review station 104.

[0041] In FIG. 8, the console 118 and the dedicated review station 104 are both connected to a common network 802, such as one part of a radiology information system (RIS), a hospital information system (HIS), etc. A PACS 804 is also shown connected to the common network 802. In a variation, the PACS 804 is omitted. In this example, the console 118 and the dedicated review station 104 (and the PACS 804) are all configured to save, receive and/or transfer images using the DICOM standard. Furthermore, the console 118 and the dedicated review station 104 communicate with each other over the common network 802. The console 118, once an image is generated by the reconstructor 116, automatically transfers the image to the dedicated review station 104 via the DICOM standard over the common network 802.

[0042] FIG. 9 schematically illustrates a variation of the system described in connection with FIG. 8. The console 118 and the PACS 804 are likewise connected to the common network 802. In this variation, the console 118 and the dedicated review station 104 are connected via a dedicated connection 902 there between. In one instance, the dedicated connection 902 is a dedicated network cable, and communication there between is independent of the bandwidth of the network 802. The console 118, once an image is generated by the reconstructor 116, transfers the image to the dedicated review station 104 via the DICOM standard over the dedicated connection 902. This approach may transfer image files over quicker than the approach described in connection with FIG. 8 since the connection 902 is a dedicated connection.

[0043] FIG. 10 schematically illustrates another variation of the system described in connection with FIG. 8. The console 118 and the PACS 804 are likewise connected to the common network 802. In this variation, the reconstructor 116 and the dedicated review station 104 are connected via a direct connection 1002 there between. The reconstructor 116 is configured to automatically transfer images directly to the dedicated review station 104 using a non-DICOM protocol, such as a proprietary protocol and/or other protocol. The direct connection 1002 can be wired and/or wireless, and the data link can be point-to-point, Ethernet, etc. This approach may transfer image files over quicker than the approach described in connection with FIGS. 8 and 9 since the images are not converted into and/or from the DICOM format.

[0044] FIG. 11 schematically illustrates another variation where the dedicated review station 104 is also in communication with a portable device(s) 1102 such as a smartphone, a laptop, a tablet, etc. In one instance, the dedicated review station 104 transfers screen copy of what is displayed on the dedicated review station 104 to the portable device(s) 1102. In this instance, the screen copy mirrors what is displayed on the dedicated review station 104. In another instance, the dedicated review station 104 transfers the same set of images currently shown via the dedicated review station 104, and the portable device(s) 1202 includes an application to display an image and manipulate it via at least a subset of the functions provided by a visualization algorithm, as described herein and/or otherwise. Additionally or alternatively, the images are transferred directly from the console 118 and/or the reconstructor 116 to the portable device(s) 1102.

[0045] FIG. 12 illustrates a variation in which the dedicated review station 104 further includes one or more device interfaces 1202.sub.1, . . . , 1202.sub.M, where M is an integer greater or equal to one. Examples of interfaces include but are limited to at least one physiological sensing device such as a blood pressure (BP) device interface, an electrocardiogram (ECG) interface, a pulse oximetry (SO.sub.2) device interface, a heart rate monitor, and/or other device the measures, senses, and/or derives a vital sign. In this variation, the data received (e.g., a signal indicative of a vital sign, etc.) from one or more corresponding devices through the one or more device interfaces 1202.sub.1, . . . , 1202.sub.M, is also displayed via the dedicated review station 104.

[0046] In another variation, the dedicated review station 104 includes and/or is in communication therewith a computing system including computer-assisted diagnostic (CADx) system, computer-assisted detection (CADe), and/or the like. In general, CADx and CADe systems are configured to assist a clinician with interpreting a medical image. In one instance, this includes marking conspicuous structures and sections and/or evaluating conspicuous structures.

[0047] FIG. 13 illustrates an example method in accordance with an embodiment herein.

[0048] It is to be appreciated that the ordering of the above acts is not limiting. As such, other orderings are contemplated herein. In addition, one or more acts may be omitted and/or one or more additional acts may be included.

[0049] At 1302, a scan of an object or subject is performed.

[0050] At 1304, volumetric image data is generated from the acquired data.

[0051] At 1306, images of the volumetric image data are automatically transferred to the dedicated review station 104 as they are generated, as described herein and/or otherwise.

[0052] At 1308, received images are displayed by the dedicated review station 104 in independent view ports, as described herein and/or otherwise.

[0053] At 1310, displayed images are visualized independent of each other.

[0054] The above may be implemented by way of computer readable instructions, encoded or embedded on computer readable storage medium, which, when executed by a computer processor(s), cause the processor(s) to carry out the described acts. Additionally or alternatively, at least one of the computer readable instructions is carried by a signal, carrier wave or other transitory medium, which is not computer readable storage medium.

[0055] While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiments. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims.

[0056] In the claims, the word comprising does not exclude other elements or steps, and the indefinite article a or an does not exclude a plurality. A single processor or other unit may fulfill the functions of several items recited in the claims. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measured cannot be used to advantage.

[0057] A computer program may be stored/distributed on a suitable medium, such as an optical storage medium or a solid-state medium supplied together with or as part of other hardware, but may also be distributed in other forms, such as via the Internet or other wired or wireless telecommunication systems. Any reference signs in the claims should not be construed as limiting the scope.
