Method of recognizing subdivision pattern of radiation images.

摘要

A method of recognizing a subdivision pattern of radiation images comprises the steps of, in the case where subdivision image recording has been carried out by exposing each of a plurality of predetermined subdivisions on a stimulable phosphor sheet to radiation, detecting prospective edge points, which are considered to be an edge of a subdivision line between the subdivisions, from image signals detected from a stimulable phosphor sheet region as the boundary between the subdivisions, and discriminating whether the prospective edge points stand or do not stand in a straight line. An image subdivision pattern on the stimulable phosphor sheet is recognized by judging that the subdivisions line is present in the case where the prospective edge points stand in a straight line, and judging that no subdivision line is present in the case where the prospective edge points do not stand in a straight line.
