The present invention relates to processing X-ray images of an object. In order to improve the accuracy for interactive geometrical measurements, a device (10) for processing of an X-ray image of an object (30) is provided. The device comprises an input unit (12) and a processing unit (14). The input unit is configured to provide a shape related information (16) from an object (30) to be irradiated. The input unit is also configured to provide a generic object model (20), and to provide an actual X-ray image (18) of the object. The processing unit is configured to adapt the generic object model based on the shape related information in order to generate an individual object model (22). The processing unit is also configured to determine, based on the individual object model, an individual image processing modificator (24) for processing at least one part of the X-ray image, and to apply the individual image processing modificator for further processing of the X-ray image.

The present disclosure relates to a system and method for digital radiography. The system may include an X-ray generation module, an X-ray acquisition module, a control module, a support module and a power supply module. The system may include one or more moving components. The X-ray acquisition module may have different configurations, such as a vertical configuration, a horizontal configuration and a free-style configuration. The control module may be configured for controlling the motion of the moving components, the selection of an X-ray acquisition module of a specific configuration, and parameters of the X-ray exposure and image acquisition. The support module may include a system of guiding rails. The power supply module may include a supercapacitor.

Accuracy enhancing systems, devices and methods are provided using data obtained from inertial measurement units (IMUs). IMUs are provided on one or more of a patient, surgical table, surgical instruments, imaging devices, navigation systems, and the like. Data from sensors in each IMU is collected and used to calculate absolute and relative positions of the patient, surgical table, surgical instruments, imaging devices, and navigation systems on which the IMUs are provided. The data generated by the IMUs can be coupled with medical images and camera vision, among other information, to generate and/or provide surgical navigation, alignment of imaging systems, pre-operative diagnoses and plans, intra-operative tool guidance and error correction, and post-operative assessments.

Various methods and systems are provided for a set of devices for an imaging system. In one example, the set of devices includes a first device configured to obtain a first set of image data and a second device configured to obtain a second set of image data along at least one dimension. The first and second sets of data may be compiled to generate a field-of-view (FOV) preview.

An X-ray imaging system includes an X-ray irradiation unit, an X-ray detection unit, an imaging unit that acquires a subject image obtained by imaging an appearance of the subject, a position information acquisition unit that acquires a position information of the subject captured in the subject image, a target position acquisition unit that acquires a target position according to imaging conditions, and a projection unit that projects a marker indicating a contour of the subject for guiding a position of the subject to be the target position acquired by the target position acquisition unit, onto an imaging position that is the subject or a surface to which the subject is fixed.

The present invention relates to positioning a medical imaging system in relation to an object. In order to provide improved positioning possibilities which facilitate the workflow during an intervention, a medical imaging apparatus (10) is provided with an image acquisition arrangement (12), which is positionable in relation to an object (16) to acquire image data (18) of the object from different directions. An output unit (14) is arranged to provide the image data. According to the invention, first movement direction indicators (22) are provided to indicate possible movement directions of the image acquisition arrangement in relation to the object. Further, a display apparatus (24), comprising a display area (26) to display image data (30) of an object provided by an image acquisition arrangement and a movement direction indication (28), may be provided, wherein the movement direction indication is configured to provide second movement direction indicators (32) in relation to the displayed image data of the object to indicate possible movement directions of the image acquisition arrangement in relation to the object. The first movement direction indicators and the second movement direction indicators are equivalent.

An imaging position correction application introduction support system is provided with a storage unit and a display unit. The imaging position correction application introduction support system is configured to cause the storage unit to store at least one of the number of times the imaging position correction application was used and a degree of correction when the relative position of the X-ray irradiation unit with respect to the specific site of the subject was corrected by the imaging position correction application, as the tentative use information on when the imaging position correction application is tentatively used. The display unit displays the information based on the tentative use information.

The present disclosure relates to a medical imaging system having an X-ray source, a detector and a processing system. The the X-ray source is collimated to produce a diverging beam of radiation and transmits X-rays through an object. The detector includes detector pixels arranged in at least one row and is operative to receive the X-ray energy of the X-rays after having passed through the object. The processing system is programmed to select an initial height of the object with respect to the X-ray source plane and determine an initial time delayed summation (TDS) shift frequency based on the initial height. The processing system performs a first scan of the object based on the TDS shift frequency and determines a new height of the object based on a beam angle and an overlap of adjacent images. A new TDS shift frequency is determined based on the new height of the object if the initial height and the new height are not substantially same. The processing system then performs a second scan of the object based on the new TDS shift frequency. The processing system is further programmed to generate an image of the object based on detected X-ray energy at the X-ray detector based on the first scan and the second scan.

An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.
