PROBLEM TO BE SOLVED: To provide a mammography apparatus capable of executing an overall examination and local examination of breasts without changing a compression plate and executing elastography further.SOLUTION: The mammography apparatus includes: an imaging base 4 for supporting the breasts of a subject a compression plate 5 which is provided movably in a direction of approaching and separating from the imaging base 4, and compresses the breasts supported on the imaging base 4 an X-ray output part 6 for outputting X-rays to be radiated to the breasts through the compression plate 5 an X-ray detection part 7 for detecting the X-ray which has transmitted through the breasts and a partial compression pressure varying part 12 for partially changing the compression pressure of the compression plate 5 acting on the breasts.COPYRIGHT: (C)2012,JPO&INPIT【課題】乳房の全体的な検査と局所的な検査とを圧迫板を交換することなく行え、さらにエラストグラフィを可能とするマンモグラフィ装置を提供する。【解決手段】マンモグラフィ装置において、被検体の乳房を支持する撮影台4と、撮影台4に対して接離する方向に移動可能に設けられ、撮影台4上に支持された乳房を圧迫する圧迫板5と、圧迫板5を介して乳房に照射するX線を出力するX線出力部6と、乳房を透過したX線を検出するX線検出部7と、乳房に対して作用する圧迫板5の圧迫圧を部分的に変化させる部分的圧迫圧可変部12とを備える。【選択図】図1
