PROBLEM TO BE SOLVED: To provide a method for automatically collating the slice picture of a chest three-dimensional tomographic by which the slice pictures at the same position of a body are automatically extracted from the chest three- dimensional tomographic pictures of two pairs of the same persons, and to provide a recording medium in which the program for the method is recorded. SOLUTION: A diagnostic picture and a comparison picture are inputted to a computer (S1 and S2), the comparison picture is matched with the diagnostic picture by the parameter change (parallel movement, enlargement and reduction, and rotation) of the comparison picture (S3 and S4), the mean value of the absolute value of the difference of the concentration of each picture element is obtained as a defference Diff for the AND area of the both pictures (S5 and S6),the minimum difference Dm ,n of the defference Diff is decided by changing the parameter (S7-S9), and the comparison picture having the minimum value among the minimum defference Dm ,n is decided for each comparison picture (S10-S12). The comparison picture having the minimum value is decided also for each diagnostic picture, and a corresponding table is prepared (S13-S15). |
