Matching procedure: Block contours were transferred from the mantle-field portal film of the treated patient (A) to the 0-degree digital radiographic reconstruction (DRR) of the CT data set of the test patient (C). This was achieved by matching the portal film to the DRR based on corresponding points of the heart contour (A and B). The quality of the match, with regard to the heart, is illustrated by the agreement of test points at the heart outline in A and B.
