DIAGNOSTIC IMAGING DEVICE AND DIAGNOSTIC METHOD

摘要

A diagnostic imaging device, whereby: a tissue site to be diagnosed is irradiated with light, which substantially sends back reflected light alone without emitting autofluorescence, emitted from a first light source (110); a reflection light image of the tissue site obtained by the reflected light is captured; the tissue site is irradiated with light, which emits autofluorescence, emitted from a second light source (120); an autofluorescent image of the tissue site obtained by the autofluorescence is captured; the difference between the luminescence of said reflected light image and the luminescence of said autofluorescent image is calculated; and a difference image of the aforesaid two images are formed. When the tissue site contains a cancer tissue, the cancer tissue can be clearly observed in the difference image.
