Abstract
A system and method for X-ray computed tomography includes a robotic arm that moves an X-ray emitter around a subject in a curvilinear path and an X-ray detector that captures 2-dimensional views while the subject is scanned. Movements of the emitter and detector are coordinated such that the position and angle of the emitter relative to the detector remains substantially constant during scanning. A processor uses computed tomography to reconstruct an image of the subject from the captured 2-dimensional views. The robotic arm varies the pitch of the X-ray emitter during the scan to enhance the spatial resolution of the reconstructed image. The processor generates a projection transformation matrix based on movement of the robotic arm for each captured 2-dimensional view that is applied during reconstruction.
