SYSTEMS AND METHODS FOR IMAGING DYNAMIC PROCESSES

摘要

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.

1. An imaging system, comprising:
one or more radiation sources configured to transmit x-ray radiation towards a subject for imaging a dynamic process in a region of interest of the subject; one or more detectors configured to acquire projection data corresponding to the region of interest; and a computing device operatively coupled to one or more of the radiation sources and to the detectors, wherein 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;provide control signals for performing one or more tomosynthesis scans using one or more tomosynthesis trajectories for acquiring tomosynthesis data following onset of the dynamic process; andreconstruct one or more images representative of the dynamic process using the reference data, the tomosynthesis data, or a combination thereof
