PROBLEM TO BE SOLVED: To provide a stereo X-ray imaging apparatus and a stereo X-ray imaging method which reduce the exposure dose of X-rays of a patient while facilitating recognizing the position of an area of interest.SOLUTION: The stereo X-ray imaging apparatus includes: a first X-ray focal point 7 and a second X-ray focal point 8 for applying X-rays; an X-ray detector that detects the X-rays emitted by the first X-ray focal point 7 and the second X-ray focal point 8 and transmitted through an object P; and a stereo display unit that stereoscopically displays the X-rays detected by the X-ray detector, wherein an X-ray irradiated area 11 based on the first X-ray focal point 7 is set to be included in another X-ray irradiated area 12 based on the second X-ray focal point 8.【課題】関心領域の位置を容易に把握できるようにしつつ、患者のX線の被曝を低減する。【解決手段】X線を照射する第一X線焦点7および第二X線焦点8と、第一X線焦点7および第二X線焦点8が発して被写体Pを透過したX線を検出するX線検出器と、X線検出器が検出したX線をX線画像として表示するステレオ表示部とを有し、第一X線焦点7によるX線照射領域11は、第二X線焦点8によるX線照射領域12に包含されるように設定される。【選択図】図3
