PROBLEM TO BE SOLVED: To improve diagnosability by reducing density differences in a radiographic image of the breast.SOLUTION: The radiographic instrument 10 can improve diagnosability by reducing density differences in the radiographic image of the breast N by being provided with a radiographing table 22 having a plane radiographing surface 20 against which the breast N is pressed, and a flexible compression plate 40 enabled to approach and separate from the radiographing surface 20, pressing the breast N against the radiographing surface 20 shaped into a convexity having a fixed thickness and projecting the center side toward the radiographing surface 20 side more than the periphery.COPYRIGHT: (C)2012,JPO&INPIT【課題】乳房の放射線画像の濃度差を小さくして診断性を向上させること。【解決手段】乳房Nが押し付けられる平面状の撮影面20を有する撮影台22と、撮影面20に対して接離可能とされ撮影面20に乳房Nを押し付けると共に板厚が一定で且つ外周縁部よりも中央側が撮影面20側へ突出した凸形状とされた可撓性を有する圧迫板40と、を放射線撮影装置10が備えることで、乳房Nの放射線画像の濃度差を小さくして診断性を向上させることができる。【選択図】図6
