Problem to be solved: to provide a mammography apparatus and a puncture needle driving method in which a puncture needle can be automatically positioned at an insertion position and a punching angle according to a puncture object position, and a puncture needle is automatically used.The mammography apparatus according to the embodiment comprises a compression plate, a support part, a calculating part, and a drive control unit.The pressure plate has an opening surface having a number of apertures formed thereon, and is pressed against the breast surface and an opening surface on which the breast of the subject is placed.The support supports the puncture needle to puncture the compressed breast through one of the plurality of openings to variable the insertion position and the insertion angle.The calculating part calculates a punching opening for punching the puncture needle out of a plurality of openings, the insertion position and the degree of piercing angle based on the position of the puncture object of the breast and the position of each opening of the plurality of openings.The drive control section drives the support portion so as to position the puncture needle on the straight line having the piercing angle, which is determined by the calculation section, through the insertion position.Diagram【課題】多孔圧迫板を用い、穿刺対象部位に応じた刺入位置および刺入角度に穿刺針を自動で位置させることができる乳房撮影装置および穿刺針駆動方法を提供する。【解決手段】実施形態に係る乳房撮影装置は、圧迫板と、支持部と、算出部と、駆動制御部とを備える。圧迫板は、数の開口が形成された開口面を有し、被検体の乳房が載置された載置面と開口面とで乳房を圧迫して挟持する。支持部は、圧迫された乳房を複数の開口のいずれか１つを介して穿刺する穿刺針を、刺入位置可変および刺入角度可変に支持する。算出部は、乳房の穿刺対象部位の位置と複数の開口のそれぞれの開口の位置とにもとづいて、複数の開口のうちの穿刺針を刺入する刺入開口と、刺入位置と、刺入角度と、を求める。駆動制御部は、算出部が求めた刺入位置を通り刺入角度を有する直線上に穿刺針を位置させるように支持部を駆動する。【選択図】 図１
