摘要： A compact apparatus can form multi-X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi-electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi-X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

摘要： A mammography apparatus includes a detector that detects X-rays transmitted through a breast, and an optically transparent or semitransparent pressing panel for pressing the breast. The apparatus further includes a near infrared ray source that provided between the X-ray source and the pressing panel and arranged in a two-dimensional shape in alignment with the pressing panel, and that is movable between a first position in close contact with the pressing panel and a second position outside an X-ray image capture region. Near infrared image capture is carried out using the near infrared ray source by causing the near infrared ray source to be in the first position, and the near infrared ray source is caused to retract to the second position when carrying out X-ray image capture using the X-ray source.
