Light power treatment system having visualization function

Abstract

The invention is suitable for the light power treatment technology field and provides a light power treatment system having a visualization function. Exposure and readout sequence signals outputted by an electronic CCD or a CMOS optical system are loaded through a triggering port to a chopper of a light synchronization module, so the chopper is controlled for realizing disconnection or instant conduction with a light path at an exposure stage of the electronic CCD or the CMOS optical system, continuous conduction with the light path is realized at a readout stage, and synchronization pulse treatment laser is further generated; if no reflected or scattered treatment laser is received by the electronic CCD or the CMOS optical system because of disconnection with the light path at the exposure stage, organization image visualization in a light power treatment process can be realized; if the reflected or scattered treatment laser is received at the exposure stage, not only can organization images be provided to doctors in real time, but also a treatment spot boundary can be further displayed in the organization images in real time, and thereby vivid image visualization in the light power treatment process is realized.

Description

technical field [0001] The invention belongs to the technical field of photodynamic therapy, in particular to a photodynamic therapy system with visualization function. Background technique [0002] my country is one of the high incidence areas of cancer in the world. The World Health Organization published the "Global Cancer Report" on February 3 this year. According to a study, the number of new cancer cases in China ranked first in the world in 2012, and nearly 50% of the new cases occurred in China. Moreover, the number of new cases and deaths of the four major malignant tumors of esophageal cancer, gastric cancer, liver cancer and lung cancer in my country ranks first in the world. Taking esophageal cancer as an example, according to the data released by the World Health Organization, there are about 260,000 new cases of esophageal cancer in my country every year, the incidence rate is 16.7 / 100,000 people, and the mortality rate is 13.4 / 100,000 people. More than half o...
