Abstract

A method to accurately and rapidly locate tumor, comprising the steps of using a immobilization module to ensure the consistency of patient positioning, verification and the position of each treatment; using a locating and marking module comprising a locating and marking tool for locating and marking; using a data input module to obtain the data required for a calculation of Optical Positioning System in radiotherapy; and using a positioning module to calculate the deviation between the planned isocenter and the machine isocenter, and to provide prompts of patient positioning.

Description

technical field [0001] The invention relates to a method for rapidly and accurately locating tumor positions, in particular to a method for real-time, precise and rapid locking of the treatment center coordinates and displaying the deviation from the isocenter coordinates in radiotherapy. Background technique [0002] Radiation therapy is an important means of cancer treatment. In the case of patients who are difficult to undergo surgery, radiation therapy has the advantages of simple treatment methods and significant effects, and can effectively prolong the life of patients, so it is widely used. [0003] In the case of precision radiation therapy, it is necessary to solve the problem of whether the tumor localization is accurate during radiation therapy. In the actual radiotherapy operation, the errors of radiotherapy equipment such as laser lamps, analog positioning machines, accelerators and other systems, as well as human operation errors, will make it difficult to guar...
