Mammography apparatus

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.

主权项

1. A detection apparatus comprising:
a near infrared ray source; an X-ray source; a detection unit configured to detect near infrared rays emitted from said near infrared ray source and X-rays emitted from said X-ray source, said detection unit having a light-receiving surface to receive the near infrared rays and X-rays; a grid provided on a side of said light-receiving surface of said detection unit; and a control unit configured to control said near infrared ray source, when irradiating the near infrared rays, to advance into an opposite side of said light-receiving surface of said detection unit, and to control said grid to evacuate to an area which does not intercept the near infrared rays irradiated to said light-receiving surface of said detection unit, and when irradiating the X-rays, to control said grid to advance into an inside of said detection unit, and said near infrared ray source to evacuate to an area which does not intercept the X-rays irradiated to the side of said light-receiving surface of said detection unit.
