A first light source emits near-infrared radiation with a wavelength near 810 nm, which is excitation radiation for exciting indocyanine green, a second light source emits a violet light with a wavelength of 410 nm that is excitation radiation for exciting PpIX, and a third light source emits white light. An imaging portion comprises a first imaging element able to capture visible light, a second imaging element able to capture red light that is emitted by the PpIX, and a third imaging element able to capture near-infrared light emitted by the indocyanine green. |

1. An imaging device wherein a first fluorescent dye that emits light through being illuminated with excitation radiation, and a second fluorescent dye that emits light through being illuminated with excitation radiation, and that has the nature of a metabolite thereof accumulating in a tumor, are adapted to be placed in the body of a patient, and fluorescent light from the first fluorescent dye and fluorescent light from the second fluorescent dye are imaged, comprising:
a first light source for emitting, toward the patient, light of a first wavelength for stimulating the first fluorescent dye; a second light source for emitting, toward the patient, light of a second wavelength for stimulating the second fluorescent dye; a third light source for emitting, toward the patient, a white light; a plurality of imaging elements; a filter for selectively causing first fluorescent light that is emitted by the first fluorescent dye, second fluorescent light that is emitted by the second fluorescent, and visible light that is reflected by the patient, to be incident into the plurality of imaging elements; and an image processing portion for displaying a first fluorescent image, a second fluorescent image, and a visible image on a displaying portion based on the first fluorescent light, the second fluorescent light, and the visible light captured by the plurality of imaging elements through the filter. |
