摘要
The authors devised a new method using measure plates for the endoscopic measurement of gastric ulcer area. A grid composed of 2.5-mm squares was photographed by the endoscope with lens-object-distance (LOD) being changed every 2.5 mm precisely, and the obtained images of the square pattern were printed on glass plates, which were used as measure plates. The ulcer size was determined by mounting an endoscopic photograph of the ulcer on the corresponding glass plate with the same LOD, projecting them on the screen by a projector and counting the number of squares within the ulcer area. In this way the gastric ulcer size could be determined with an average aberration ratio of 5.6% or less, irrespective of LOD.
