SWITCHED PHOTODYNAMIC THERAPY APPARATUS AND METHOD

摘要

A photodynamic therapy apparatus and method in which (1) phototoxic drug is supplied to a target tissue, (2) delivery of drug activating light to the target tissue through probes is controlled by sequential selection of operation of the probes, (3) an automatic radiance probe is used for efficient optical characterization of the target tissue, and (4) an optical dose is monitored by sequential selection of probes as transmitters and receivers.
