ABSTRACT:
A computer system automatically takes a sequence of stepping images from peripheral angiography and mosaics them into a single full-leg display by globally matching the bone and the vessel by measuring an overlapping ratio and by locally refining detailed anatomical features using deformation. The system combines multiple evidence in the entire overlapped image/candidate rows and maximizes the ratio of overlap. This approach takes evidence from the multiple rows and provides a more reliable result. In addition, local refinement is applied to compensate for the possible mismatch and nonlinear patient movement.
