摘要： Provided are one or more systems and/or techniques for filtering noise from a space-variant image. For each of the plurality of pixels included in the space-variant image, a variance of the pixel is detected, and a variance reduction power is generated based on a relationship between the detected variance of the pixel and a target variance specified by a user. At least a first defined kernel is selected from a database populated with a plurality of defined kernels that are available to be selected for filtering the image data for the pixel. The image data for the pixel is recursively filtered during a plurality of filter iterations to cause the variance of the pixel to approach the target variance. The first defined kernel is applied to the image data for the pixel during at least one of the filter iterations.

摘要： 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.

摘要： Among other things, one or more techniques and/or systems for calibration of a radiation system to compute a gain correction(s) are provided. A calibration procedure is performed during which a portion of the detector array is shadowed by an object, causing the detector array to be non-uniformly exposed to radiation. A portion of a projection generated from the calibration procedure and indicative of radiation that did not traverse the object is separated from a portion of the projection indicative of radiation that did traverse the object, and a gain correction(s) is computed from the portion of the projection indicative of radiation that did not traverse the object (e.g., and is thus indicative of radiation that merely traversed air).

摘要： A receiving antenna for wirelessly receiving data between a stator of a computed tomography (CT) imaging modality and a rotor of the CT imaging modality is provided. The rotor rotates about a rotational axis. The receiving antenna includes a dielectric portion and a conductive portion coupled to the dielectric portion. A second surface of the conductive portion extends between a first end and a second end along a conductive axis that is substantially perpendicular to the rotational axis. The second surface of the conductive portion has a first length at a first length location along a first length axis that is substantially parallel to the conductive axis. The second surface of the conductive portion has a second length at a second length location along a second length axis that is substantially parallel to the conductive axis. The first length is different than the second length.

摘要： An X-ray inspection system includes at least one display monitor and a console. The console includes at least two different visualization algorithms and a processor. The processor is configured to process volumetric image data with a first of the at least two different visualization algorithms and produce first processed volumetric image. The processor is further configured to process the volumetric image data with a second of the at least two different visualization algorithms and produce second processed volumetric image. The processor is further configured to concurrently display the first and second processed volumetric image data via the display monitor. The volumetric image data is indicative of a scanned object and items therein.

摘要： Among other things, one or more techniques and/or systems are described for defining imaging modes and for operating a photon counting radiation imaging system. A set of imaging modes with different counting schemes may be defined such that counting schemes will count detection events of a set of radiation events in different manners. For example, a first counting scheme may count primary detection events in a primary counter and secondary detection events in a secondary counter. A second counting scheme may count primary and secondary detection events in the primary counter. A third counting scheme may merely count detection events occurring within a primary detector cell associated with the primary counter. A fourth counting scheme may combine energy of detection events into merged energy. A selected imaging mode may be applied to the photon counting radiation imaging system in order to achieve desired image scanning characteristics (e.g., spatial resolution, dose savings, spectral ability).

摘要： 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.
