PROBLEM TO BE SOLVED: To provide a mammography apparatus and a hand switch that an operator can operate easily when positioning breasts.SOLUTION: A mammography apparatus includes an X-ray tube for generating an X-ray to be irradiated onto a subject, an X-ray detector for detecting an X-ray that penetrates the breasts of the subject, a compression plate for compressing the breasts of the subject, a compression plate drive part for compressing the breasts by driving the compression plate, a hand switch provided with an input part for inputting a signal to activate the compression plate drive part, which is shaped so as to be gripped by one hand of an operator, an X-ray tube for irradiating an X-ray onto the breasts of the subject in a state that the breasts are compressed by the compression plate, and an image processing part for generating an X-ray image of the breasts based on the X-ray detected by the X-ray detector.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】 操作者が乳房のポジショニング時に操作しやすいマンモグラフィ装置及びハンドスイッチを提供することである。【解決手段】 実施形態のマンモグラフィ装置は、被検体に照射するＸ線を発生するＸ線管と、被検体の乳房を透過したＸ線を検出するＸ線検出器と、被検体の乳房を圧迫する圧迫板と、圧迫板を駆動させることで乳房を圧迫する圧迫板駆動部と、圧迫板駆動部を動作させる信号を入力する入力部を備え、操作者の片手に把持可能な形状のハンドスイッチと、圧迫板により乳房が圧迫された状態において、被検体の乳房にＸ線を照射するＸ線管と、Ｘ線検出器にて検出されたＸ線に基づいて、乳房のＸ線画像を生成する画像処理部とを具備する。【選択図】図３
