Abstract

Provided is a photodynamic therapy apparatus which is capable of increasing the effect of photodynamic therapy by forming an open channel for delivering a light-sensitizer and securing light transmission depth in a biological barrier covering target biological tissue. The photodynamic therapy apparatus is characterized by comprising: a light source module which emits light; an ultrasonic module which outputs ultrasound; a detecting module which detects a result of the output of ultrasound; and an electronic control module which feedback-controls the output of the ultrasonic module according to the detection result of the detection module.
