Radiation imaging apparatus and stereoscopic image display method

A stereoscopic image display method, for displaying a stereoscopic image employing a right eye image and a left eye image by using a radiation imaging apparatus comprising:

• a radiation detector that detects irradiated radiation and outputs the detected radiation as radiation image signals;
• a radiation source that irradiates radiation toward a subject from three different imaging direction, including a first imaging direction that forms the smallest angle with respect to a direction perpendicular to a detecting surface of the radiation detector, a second imaging direction and a third imaging direction that form angles with respect to the direction perpendicular to the detecting surface of the radiation detector greater than that formed by the first imaging direction;
• and a grid provided between the subject and the radiation detector that absorbs scatters rays of the irradiated radiation, configured to be at the most appropriate placement for the first imaging direction from among the three imaging directions;
• comprising:
• receiving input of a user's dominant eye;
• and
• displaying a set of radiation image signals obtained by the first imaging direction as the image for the dominant eye, and one of a set of radiation image signals obtained by the second imaging direction and a set of radiation image signals obtained by the third imaging direction corresponding to the opposite side of the dominant eye as an image for the other eye.
