Abstract: Provided are one or more systems and/or techniques for mitigating motion artifacts in a computed tomography image of an anatomical object. Extended scan data is received and includes projections and backprojections acquired for parallel rays emitted by a radiation source at different angular locations within a first range of source angles. The projections and the backprojections are compared to identify differences between the projections and the backprojections at the different angular locations. Movement of the anatomical object during acquisition of the extended scan data at the different angular locations is quantified, and short scan data is identified. The short set includes a subset of the extended scan data acquired at different locations within a second range of source angles where the quantified movement of the anatomical object is less than a movement threshold. The computed tomography image of the anatomical object is reconstructed from the short scan data.

Abstract: Among other things, computed tomography (CT) systems and/or techniques for generating projections images of an object(s) under examination via a CT system are provided. The projection images of the object may represent a projection of the entire object or merely a portion of the object, such as a slice of the object. A surface about which the projection image is focused is defined and data yielded from a plurality of views of the object is mapped to the surface. In some embodiments, such a mapping comprises mapping data corresponding to a first view and yielded from a first detector cell to a first point on the surface, mapping data corresponding to the first view and yielded from a second detector cell to a second point on the surface, and/or mapping data corresponding to a second view and yielded from the first detector cell to a third point on the surface.

Abstract: Among other things, a guide unit and a radiation system including a guide unit are provided. The guide unit limits axial movement of a rotatable structure supporting a radiation source and a detector array of the radiation system. Embodiments of the guide unit include a frame member configured to be supported by a stationary unit that forms a portion of the radiation system. A guide wheel coupled to the frame member is configured to roll along a periphery of the rotatable structure of the radiation system as the rotatable structure supporting the radiation source and the detector array is rotated about an axis of rotation during operation of the radiation system. A wheel adjustment system coupled to the frame member linearly translates the guide wheel toward the periphery of the rotatable structure supported by the stationary unit of the radiation system.

Abstract: Among other things, a data communication system wirelessly transmits data between a stator and a movable unit (e.g., a rotor) as part of a computed tomography (CT) imaging modality. The data communication system includes a first magnetic portion including a first magnetic material. The first magnetic portion extends along a first axis. The data communication system includes a first conductive portion including an electrically conductive material. The first conductive portion is at least partially surrounded by the first magnetic portion. The first conductive portion extends along a second axis that is substantially parallel to the first axis. The first conductive portion will at least one of generate an electromagnetic field corresponding to data to be transmitted, or have induced therein a current based upon a received electromagnetic field, where the current is a function of the data to be transmitted.

Abstract: Among other things, one or more systems and/or techniques are described for shaping a profile of radiation attenuation in a fan-angle direction via a pre-object filter (e.g., a bowtie filter) based upon a profile of an object. For example, a pre-object filter may be at least partially rotated about a filter axis and/or may be translated in a direction parallel to a direction of conveyance of the object under examination to adjust a profile of radiation attenuation in the fan-angle direction. Further, in one embodiment, the profile of radiation attenuation may be reshaped during rotation of the radiation source about the object to adjust an amount of radiation attenuation in the fan-angle direction (e.g., to adjust a profile of radiation attenuation as a shape of the object changes from a perspective of a radiation source as the radiation source is rotated about the object).

Abstract: A transport apparatus of an X-ray inspection system includes an inspection region with an entrance and an exit. The transport apparatus further includes a loading region disposed at the entrance of the inspection region, the loading region. The loading region includes a first set of X-ray attenuating curtains and a first curtain mover, which moves the curtains of the first set of X-ray attenuating curtains into and out of the loading region between areas that support objects for inspection. The transport apparatus further includes a conveyor device which moves an object for inspection residing in one of the areas from the loading region to the inspection region for inspection.

Abstract: Among other things, a detector unit for a radiation detector array is provided. The detector unit includes a radiation detection sub-assembly including a scintillator and a photodetector array. A first routing layer is coupled to the photodetector array of the radiation detection sub-assembly at a first surface of the routing layer. An electronics assembly includes an analog-to-digital converter that converts an analog signal to a digital signal. A second routing layer is disposed between the A/D converter and the first routing layer. A shielding element is disposed between the A/D converter and the second routing layer. The shielding element shields the A/D converter from the radiation photons. The second routing layer couples the electronics sub-assembly to the first routing layer. A first coupling element couples the A/D converter to the second routing layer.
