補償撮影法 : 第2報 プラッシエル・フィルタ法について

抄録

The human body shows various density gradients on the radiographs. When those density gradients are too high, the compensated radiographic techniques will be helpfull for the equalization of the density gradients. Thus radiographys with more informative areas on the single film may be obtained. It may be also reduce the radiation dose of the subject. On this issue, our experiences with the use of "Plasshel" for the hand-made filter are discussed. The "Plasshel" is a plastic splint which has heat plasticity.
