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, one or more systems and/or techniques for classifying an item disposed within an object are provided herein. A three-dimensional image of the object (e.g., a bag) is segmented into a set of item representations (e.g., laptop, thermos, etc.). An item is identified from the set of item representations based upon item features of the item, such as the laptop that could be used to conceal an item of interest such as an explosive. A region comprising a three-dimensional image of the item is divided into a set of sub-regions (e.g., a first sub-region encompassing a screen, a second sub-region encompassing a motherboard, etc.). The item is classified as a potential first type of item (e.g., an explosive laptop) when any sub-region has a number of voxels, with computed tomography (CT) values within a range of known CT values for a first type of item, exceeding a threshold.

Abstract: Among other things, one or more techniques and/or systems are described for processing images yielded from an examination via radiation to reduce visible noise in the images. After an image is reconstructed, a noise contribution to the image (e.g., an amount of noise in the image) is estimated to determine a target noise contribution for the image. The target noise contribution for the image may vary based upon, among other things, dose of radiation, aspects or properties of an object being imaged, etc. The image is subsequently filtered using one or more filtering techniques to generate a filtered image, and a noise contribution to the filtered image is determined. When the noise contribution to the filtered image satisfies the target noise contribution (e.g., a sufficient amount of noise has been filtered out of the image), the filtered image is combined with the reconstructed image to generate a blended image.

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).
