Abstract: The present disclosure relates to the acquisition of image data over an extended field of view using an interventional tomosynthesis system. In one embodiment, the interventional tomosynthesis system has a base offset from the longitudinal axis of a patient table, such that movement of the table relative to the imager may be performed during tomosynthesis projection acquisition. One or both of the imager and the table may move to accomplish such relative motion.

Abstract: The present approach relates to the use of a spatially registered detector docking compartment to determine source and detector alignment in a patient imaging context. In certain implementations, sensors and/or cameras provide visual data that may be analyzed to determine a spatial relation between an X-ray source and landmarks provided on a patient support surface, where the landmarks have a known spatial relationship to a detector positioned beneath the patient support surface.

Abstract: A method for X-ray imaging includes determining one or more pre-shot parameters corresponding to a region of interest in a subject based on an optical image of the region of interest obtained from an optical sensor. The method further includes controlling an X-ray device to generate a pre-shot X-ray image using a first X-ray dosage, based on the one or more-pre-shot parameters. The method also includes determining at least one main-shot parameter based on the pre-shot X-ray image. The method includes controlling the X-ray device to generate a main-shot X-ray image using a second X-ray dosage greater than the first X-ray dosage, based on the at least one main-shot parameter.

Abstract: The present discussion relates to the use of deep learning techniques to accelerate iterative reconstruction of images, such as CT, PET, and MR images. The present approach utilizes deep learning techniques so as to provide a better initialization to one or more steps of the numerical iterative reconstruction algorithm by learning a trajectory of convergence from estimates at different convergence status so that it can reach the maximum or minimum of a cost function faster.

Abstract: A method for reducing grid line artifacts in an X-ray image is disclosed, which includes acquiring an X-ray image by scanning an object, wherein the X-ray image comprises grid line artifacts; decomposing the X-ray image into a high frequency image and a low frequency image, wherein the high frequency image comprises the grid line artifacts; filtering the high frequency image to reduce the grid line artifacts in the high frequency image so as to obtain a filtered high frequency image; and combining the filtered high frequency image with the low frequency image to reconstruct an output image. A system adopting the above method is also disclosed.
