A knowledge-based position matching technique for mammographic calcifications

The purpose of this paper is to present a knowledge-based position matching technique which can be used to determine the corresponding calcifications in two views (MLO/CC) of a breast. The procedure includes two stages: First, an initial matching list is produced based on a matching parameter; then, three checking parameters are used to extract the best matching pairs from the initial list. This procedure should aid in the analysis of shapes of calcifications.
