Abstract

The invention discloses an intelligent photodynamic therapy illumination system based on an LED array. The system comprises a digital image acquisition module, a computer with digital image processingand analyzing software, a single-chip microcomputer system and the LED array. The digital image acquisition tool performs image acquisition on a lesion area to obtain a lesion image with a scale. Thecomputer with the digital image processing and analyzing software is used for carrying out digital image processing on the acquired lesion image to obtain a light-emitting time length signal of eachLED. The single-chip microcomputer system controls the LED array to emit light according to the light-emitting time length signal of each LED. According to the system, the light-emitting area of a light source can be adjusted according to the shape and range of the lesion of a patient; the local illumination dose can be adjusted according to the lesion degree of the area corresponding to the lesion; and therefore the accuracy of the photodynamic therapy process is improved.

Description

technical field

[0001] The invention belongs to the application of optics in the medical field, and in particular relates to an LED array-based intelligent photodynamic therapy lighting system. Background technique

[0002] Photodynamic therapy is a new treatment method that selectively destroys biological diseased tissues through photochemical reactions to achieve therapeutic purposes. This method has the advantages of minimally invasive, repeatable, and less toxic and side effects, so it has been widely used in the treatment of skin diseases, tumors, dentistry, orthopedics and other diseases, and has also attracted attention in the field of scientific research. The smooth progress of photodynamic therapy requires the cooperation of three major elements: photosensitizer, light source and oxygen molecules. First, the photosensitizer that enters the body through injection or smearing can selectively accumulate in the lesion tissue area, and after a period of time, a photosen...
