Intelligent light irradiation therapeutic apparatus

Abstract

The invention aims to provide the light irradiation therapeutic apparatus capable of accurately positioning the disease area of a patient and irradiating the most proper light to the disease area in order to reach the best treatment effect. The apparatus provided by the invention comprises one or more cameras and an image collection apparatus, a light irradiating system and a computing and processing unit and is characterized in that the image of the disease area of the patient is collected by one or more cameras; three-dimensional match of the disease area is built according to the space coordinate relation of multiple cameras or a projection characteristic image of the light irradiation system; a three-dimensional structure of the disease area of the patient and the position relation relative to the cameras are obtained; a light irradiation dose table needed by the disease area is generated according to a light irradiation therapeutic scheme constituted by a doctor aiming at the disease area; an inverse projection therapeutic scheme is built by the computing and processing unit according to a dose table and the coordinate relation between the light irradiation system and the cameras, so as to control the light irradiation system to realize the irradiation with the predetermined dose in the disease area; and the actual light irradiation amount of the light irradiation system can be synchronously monitored by the one or more cameras.

Description

technical field [0001] The invention relates to an optical medical device, especially a medical device that adopts the principle of light irradiation to treat patients' diseases. The system obtains the three-dimensional structure information of the diseased area and controls the light dose of the light source irradiated to the diseased area according to the preset treatment plan. Realize accurate photoirradiation therapy and evaluation. Background technique [0002] Phototherapy refers to the use of sunlight or specific wavelengths of light (such as lasers) as the light source to treat certain diseases. For example, photodynamic therapy uses a photochemical reaction to inject a certain photosensitizer into the patient's body intravenously. The photosensitizer selectively binds to the diseased cells, accumulates in the diseased cells, and undergoes a chemical reaction after being irradiated with light of a specific wavelength and energy.

Problems solved by technology

This kind of operation is time-consuming and laborious, and because of the subjectivity of human operation, the uniformity of illumination cannot be guaranteed at all.

In addition, due to the patient differences between different patients and different patient areas of the same patient, the actual light dose required is also different, which makes this scheme difficult to control
