To simultaneously refer to diagnosis support information created based on a measured value and a caliper image when the measured value is provided, in an image diagnosis device.

A measured image as a basis of diagnosis support information (measured value, analyzed result, graph) is changed in size by an image size changing means 17, a caliper mark is synthesized by a reference image creating means, and the reference image (a caliper image whose size is changed) is created. The reference image and the diagnosis support information are laid out onto a same screen by a report screen layout means 19 and are outputted by an output means 20. Thus, the diagnosis support information and the caliper image when the measured value is provided are simultaneously referred to on the same screen. Organically linked inspection information can be recognized at a glance to improve quality of the inspection result. In the case of a medical apparatus, load on a patient can be reduced due to shortage of an inspection time.
