<P>PROBLEM TO BE SOLVED: To provide a radiation imaging apparatus capable of specifying which position in the body surface of a subject is matched with a position in a pick-up image. <P>SOLUTION: The radiation imaging apparatus has both display means 6 and 6a for displaying an image 7 acquired by imaging a body to be imaged 30 and a light projection means 20 for projecting a light-projection mark 51b to the body to be imaged 30. A position of light projection on the body to be imaged 30 to which the light-projection mark 51b is projected is displayed on the image 7. The light-projection mark 51b is projected as a line of intersection 50 in which two lights 12a and 12b perpendicular to the surface of a detector and planar in visual observation intersect each other, and the position of light projection on the image is moved according to the movements of the planar lights 12a and 12b. By computing projection lines 13a and 13b formed by the projection of the planar lights 12a and 12b to the body to be imaged 30 and the projection of light-projection lines 31a and 31b to the surface and displaying them on the image 7, the position of light projection is displayed on the image 7 as a line of intersection 51b of the projection lines 13a and 13b. <P>COPYRIGHT: (C)2010,JPO&INPIT |
