Abstract |
診断用X 線画像を得るために人体にX 線を照射すると体内で散乱X 線が発生する。X 線画像の画質は散乱X線の影響を受けるので,散乱X 線の性質を知っておくことが大切である。本稿では,X 線スペクトルの測定,X 線画像の画質に及ぼす散乱X 線の影響,散乱X 線の除去方法について概説する。 Scattered x-rays occur in a patient’s body when we irradiate x-rays to the patient to obtain an x-ray image for diagnosis. As x-ray image quality is affected by scattered x-rays, we have to know the properties of scattered x-rays. This review focuses on the measurement of x-ray spectrum, influences of scattered x-rays on x-ray images, and methods of elimination of scattered x-rays. |
