System and method for motion and angulation profile consideration in tomosynthesis

摘要

Embodiments of the present invention include methods (500) and systems (10) for improved motion and angulation profiles in tomosynthesis. The method (500) involves associating a target (12) with a first (16) and a second dimension or direction. An X-ray beam (18) is then projected onto at least a portion of the target (12). The x-ray beam (18) has an origin (80) at a position (58) with respect to the first direction (16). The x-ray beam (18) also has a beam axis (34), a projection surface (28) and an angle PHI (20, 40) representing the angular distance between the beam axis (34) and the at least included portion of the target (12). The method (500) further includes varying the angle PHI (20, 40) based at least in part on the position (58) of the origin (80) in the first direction (16). The angle PHI (20, 40) is varied to substantially maintain the projection surface (28).
