PROBLEM TO BE SOLVED: To provide a radiation imaging method which can improve accuracy of matching between the radiation range of a radiation and the radiation range of visible light on an imaging surface.SOLUTION: A radiation imaging method detects the position of a subject on an imaging surface, sets an observation area of a biological tissue collected from the subject at a position different from the subject on the imaging surface on the basis of the position of the subject. The method emits visible light from a visible light source to the observation area by using a visible light shielding part transmitting visible light indicating the radiation range of the radiation emitted to the observation area and shielding visible light emitted to an area other than the observation area. The method also emits the radiation from a radiation source to the observation area by using a radiation shielding part transmitting the radiation emitted to the observation area and shielding a radiation emitted to an area other than the observation area, and generates a radiation image of the biological tissue on the basis of the radiation emitted to the observation area. |
