Abstract

The invention relates to a laser power density adjusting method, a laser power density adjusting device and a storage medium. The method includes: controlling an optical fiber in a working area, and fixing the optical fiber at a preset position in the working area; acquiring a vertical distance between a tip end of the optical fiber from a plane to be applied; acquiring a value of a scattering angle of a laser beam emitted by the optical fiber when a laser spot of the laser beam emitted by the optical fiber completely covers a region to be applied in the plane to be applied; calculating the power value of the laser according to the vertical distance between the tip end of the optical fiber from the plane to be applied, the value of the scattering angle of the laser beam and a preset targetlaser power density value; and adjusting the power of the laser to a power value to obtain the laser power density corresponding to the preset target laser power density value. The method can obtainaccurate laser power density without manual attempts and adjustments, and can improve efficiency and accuracy of laser power density acquisition.

Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to a laser power density adjustment method, device and storage medium. Background technique [0002] Nasopharyngeal carcinoma is a high-incidence malignant tumor that mainly occurs in the nasopharyngeal cavity or upper throat. People of any age group may suffer from nasopharyngeal carcinoma, and nasopharyngeal carcinoma has a genetic tendency. It is the most common cancer in China one. [0003] Photothermal therapy is a new type of minimally invasive tumor treatment method. It injects photothermal conversion materials into the human body, gathers them on the target tumor through targeting technology, and converts light energy into heat energy to kill tumors under continuous external light irradiation. tumor cells. This treatment method takes a short time, has little side effects on the human body, and greatly reduces the pain of the patient during the treatment process....
