Abstract

The invention discloses a detection method of a laser locating system of radiotherapeutic equipment. The detection method comprises the steps that a detector is fixed on the radiotherapeutic equipment, and three laser locating lamps are placed on the left, right and top of the detector respectively; the laser locating lamps send laser signals to corresponding photoelectric sensors on the detector respectively, and coordinate point set data are calculated according to the received laser signals; after horizontal angles, vertical angles, included angles and intersection coordinates of cross curves of the laser locating lamps are calculated, detection is conducted according to the parameters; accuracy error analysis is conducted. The steps further comprise detection and analysis of deviation accuracy of the three laser locating lamps. The invention further discloses a detection system of the laser locating system of the radiotherapeutic equipment. The detection method and system of the laser locating system of the radiotherapeutic equipment have the advantages that detection quality unreliability caused by dependence on personal experience and technologies during manual detection is avoided, time of detection personnel is saved, accuracy of the laser locating system is promoted greatly, the radiotherapeutic equipment is more accurate, and it is guaranteed that the most reliable treatment is conducted on tumor patients.

Description

technical field [0001] The invention relates to the technical field of medical equipment measurement, in particular to a detection method and system for a laser positioning system of radiotherapy equipment. Background technique [0002] Radiation therapy has become an important means of treating tumors. Radiation therapy for tumors must achieve four precisions: precise positioning, precise planning, precise positioning, and precise treatment. The curative effect of tumor radiotherapy is directly related to the accuracy of treatment. Reducing errors and improving treatment accuracy are the key factors for implementing precise treatment. Whether the treatment plan formulated by the radiotherapy doctor can be accurately implemented, and whether the treatment target area can be determined by the simulation positioning machine Accurate implementation of the scope requires accurate mechanical and optical parameters of the linear accelerator. [0003] The laser positioning system ...
