Abstract:
The present invention provides a device for identifying a tumor site in a subject, the device spectroscopically detecting fluorescence of protoporphyrins present in the tumor site, the protoporphyrins being protoporphyrin IX (PpIX) and photo-protoporphyrin (PPp), and the device comprising: a light irradiation unit that converts part of PpIX into PPp; a spectroscopy unit that separates PpIX fluorescence and PPp fluorescence: a spectroscopy detection unit that detects the relative fluorescence intensity of the PpIX fluorescence and the PPp fluorescence; and a tumor discrimination unit that discriminates between the tumor site and a non-tumor site based on the relative fluorescence intensity of PpIX and PPp.
