Apparatus for treatment of cancer with photodiode.

摘要

Apparatus for the treatment of a cancerous lesion part having absorbed and accumulated in advance therein a photosensitive substance with an affinity for tumors by irradiating a light energy from a light source to the cancerous lesion part comprising one or more first photodiodes (3a) adapted to excite the photosensitive substance from the ground state thereof to a singlet state of higher energy level and one or more second photodiodes (3b) adapted to exite an energy level of the photosensitive substance which has transited from the singlet state to a triplet state to a still higher energy level.
