摘要
PROBLEM TO BE SOLVED: To reconstruct a volumetric image in a three-dimensional imaging system where prior calibration of the imaging system is not possible or is not practical.;SOLUTION: A configurable volumetric representation (58) of some or all of the imaging volume is reconstructed using an imaging geometry configuration (55) estimated based on the reference markers or anatomical features represented in the projection images (53). The act of reconstructing accounts for one or more geometry configuration-dependent factors. In another embodiment, the system includes a computer (34) configured to estimate (54) an imaging geometry configuration (55) using fiducial markers or anatomical features represented in a plurality of projection images (53) and to reconstruct (56) a configurable volumetric representation (58) of some or all of imaging volume using the estimated imaging geometry configuration (55), wherein the act of reconstructing accounts for one or more geometry configuration-dependent factors.;COPYRIGHT: (C)2008,JPO&INPIT
