SWITCHED PHOTODYNAMIC APPARATUS

摘要

A photodynamic therapy apparatus and method in which (1) phototoxic drug is supplied to the arterical supply of a target tissue, (2) deliver of drug activating light to 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 target tissue and (4) optical dose is monitored by sequential selection of probes as transmitters and receivers.
