Abstract: An imaging apparatus in which positions of an X-ray image and optical image of a subject can be brought into registration with each other is provided. A half-mirror is provided between the X-ray source and subject and is configured to pass X-rays and reflect visible light. A TV camera captures the optical image of the surface of the subject reflected by the half-mirror. A display unit displays the optical image captured by the TV camera together with a reference mark indicating the reference position of this optical image, and displays, in superimposed form, an X-ray image obtained by capturing a prescribed reference object as a subject by using an X-ray imaging unit. An adjusting unit adjusts position and attitude of an X-ray detector in such a manner that the reference object displayed by the display unit will coincide with the reference mark.

Abstract: The magnification of an image is set. The distance between the positions of two designated points on the image is measured. On the basis of the set magnification set and a measurement value, an actual measurement value on the object corresponding to the measurement value of the distance between the positions of the two designated points on the image is calculated. The set magnification, the measurement value, and the calculated actual measurement value are simultaneously displayed.
