Abstract(in English) In medical x-ray examinations, x-ray collimation is frequently employed to shield the body parts from unnecessary radiation exposure and to improve the image quality. The confined regions (collimations) do not include diagnostic information. Moreover, they have been pointed out that the presence of collimations may reduce the performance on diagnosis of subtle lesions due to duzzle. Therefore, we developed a novel method to detect the boundaries between collimations and a diagnostic region as planes by use of plane detection Hough transform. The effectiveness of data compression of a processed image was greater than the original one.
