Mask digital image correction estimation method for angiography device, involves finding mobile region position for digital contrast detection images, where image correction is transformation of region from position to region of interest

摘要

The method involves detecting pixels of information in digital contrast detection images (I21) at which a mask digital image (I1) is removed. A region of interest (ROI5) is calculated in a binary cartographic image formed from the images (I21). The position of a mobile region (ROI1) maximizing a similarity criterion (IROI) with the region (ROI5) is found for each image (I21) in the image (I1). A correction estimated to be provided to the image (I1) with respect to each image (I21) is the affine transformation of the region (ROI1) from its found position to the region (ROI5).
