SYSTEMS AND METHODS FOR COHERENT SCATTER IMAGING USING A SEGMENTED PHOTON-COUNTING DETECTOR FOR COMPUTED TOMOGRAPHY

Methods and systems are provided for coherent scattered imaging using a computed tomography system with segmented detector arrays. In one embodiment, a method includes imaging a region of interest with an x-ray source and a segmented photon-counting detector array, detecting a position of an object of interest in the region of interest, selectively scanning, via the x-ray source and the segmented photon-counting detector array, the object of interest, detecting a coherent scatter signal from the object of interest with the segmented photon-counting detector array, and determining a material of the object of interest based on the detected coherent scatter signal. In this way, the coherent scatter signal may be used to identify and investigate lesions or other objects of interest within an imaged volume.
