PROBLEM TO BE SOLVED: To provide a breast imaging device capable of controlling a position of a housing support part which supports a radiation ray imaging part, based on a kind of imaging.SOLUTION: A breast imaging device can perform mammographic imaging and CT imaging by a radiation ray imaging part for holding a radiation ray generation part and a radiation ray detection part for detecting the radiation ray which is radiated from the radiation ray generation part in a manner in which the radiation ray generation part and the radiation ray detection part face each other. The breast imaging device comprises: a housing lifting part capable of lifting up and down the housing support part which supports the radiation ray imaging part and a control part for controlling lifting up and down of the housing lifting part based on a kind of imaging of mammographic imaging or CT imaging.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】撮影種別に基づいて、放射線撮影部を支持する筐体支持部の位置を制御可能な乳房撮影技術を提供すること。【解決手段】放射線発生部と放射線発生部から照射された放射線を検出する放射線検出部とを対向するように保持する放射線撮影部により、マンモグラム撮影およびCT撮影を行うことが可能な乳房撮影装置は、放射線撮影部を支持する筐体支持部を昇降移動可能な筐体昇降部と、マンモグラム撮影またはCT撮影の撮影種別に基づいて筐体昇降部の昇降移動を制御する制御部と、を備える。【選択図】 図1
