Abstract: Systems, methods and non-transitory computer readable media for imaging. The system includes one or more radiation sources and detectors configured to transmit x-ray radiation towards a subject for imaging a dynamic process in a ROI of the subject and to acquire projection data corresponding to the ROI, respectively. The system also includes a computing device operatively coupled to one or more of the radiation sources and the detectors. The computing device is configured to provide control signals for performing one or more reference scans for acquiring reference data from a plurality of angular positions around the subject and for performing one or more tomosynthesis scans using one or more tomosynthesis trajectories for acquiring tomosynthesis data following the onset of the dynamic process. Additionally, the computing device is configured to reconstruct one or more images representative of the dynamic process using the reference data and/or the tomosynthesis data.

Abstract: Disclosed aspects relate to the acquisition and processing of projection data using temporal characteristics of the imaged volume, such as the uptake and clearance of a contrast agent within the volume. Such temporal aspects may be used in the acquisition process, such as to differentially acquire images based on the propagation of the contrast agent. In addition, such temporal aspects may be used in the processing of projection data to generate differential projections (e.g., first or second order subtraction projections), compound projections synthesized using the absolute or relative maximum opacity values observed over time for a region of interest, or interpolated projections synthesized using observed opacity values at known or fixed time intervals and a derived peak opacity time.

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: C-arm systems and method for making and using continuous C-arm spin acquisition trajectories for dynamic imaging and improved image quality are described. In such systems and methods, a C-arm gantry, coupled to a C-arm support assembly, is adapted to retain an x-ray source and an x-ray detector. The C-arm gantry is selectively rotatable relative to the C-arm support assembly about both a C-arm axis and a pivot-axis to displace the x-ray source and the x-ray detector along a continuous C-arm spin trajectory. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory including a plurality of shorts arcs and a plurality of long arcs. The C-arm system is adapted for continuous three-dimensional acquisition of data along the continuous C-arm spin trajectory to provide continuous three-dimensional imaging of dynamic processes.

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 disclosure relates to the iterative reconstruction of projection data. In certain embodiments, the iterative reconstruction is a multi-stage iterative reconstruction in which different feature are selectively emphasized at different stages. Selective emphasis at different stages may be accomplished by differentially handling two or more decompositions of an input image at certain iterations and/or by differently processing certain features with respect to each stage.
