Abstract
A computer-implemented method for determining a subtraction image from a feature image and a plurality of mask images of an imaging area of an examination object is provided. A combination of the plurality of mask images weighted by mask weights is subtracted from the feature image to determine the subtraction image. The mask weights are determined in an optimization process for optimizing an image quality function for test images calculated by subtracting a combination of the mask images determined with a test set of mask weights from the feature image. The image quality function is minimized in the form of a convex quadratic program of a dimension corresponding to the number of mask images.
