Remasking is a post-processing technique used to improve misregistration artifact in digital subtraction angiography, where a frame taken after patient motion is selected as the new mask image for subtraction.
In digital subtraction angiography, misregistration (improper image registration) is the most common cause of image degradation, where patient motion results in a spatial misalignment between the mask and runoff images.
