Embodiment Construction
[0021] Such as figure 1 As shown, the positioning method of the present invention is specifically implemented as follows:
[0022] (1) Import the image data of the human body, such as CT, MRI, PET, etc., into the infrared positioning and tracking system, and display the size and position information of the image data;
[0023] (2) On the human body image data obtained in step (1), collect the position information of the infrared marker, record the position information of the active positioning ball and the passive positioning ball obtained by the infrared transmitter and receiver, and use the infrared and positioning small The ball is connected, the output of the infrared positioning tracking system is connected with the input of the computer, and the output of the computer is stored for subsequent transmission. By receiving the infrared rays in the test area, the infrared sensor feeds back the changes in the position and direction of the tool attached with the infrared refle...

The accurate positioning and tracking method and the system based on the infrared guiding have the advantages of being high in precision, strong in controllability, good in real-time performance, simple, and convenient to use.
Description
technical field [0001] The invention relates to a method and a system for positioning a patient and tracking a target area in radiotherapy. Background technique [0002] With the development of radiotherapy technology, tumor radiotherapy has entered the stage of "precise positioning, precise planning and design, and precise treatment". Precise radiotherapy technology enables modern radiotherapy with high precision, high dose, high efficacy and low damage in tumor treatment The model gradually becomes a reality. Radiotherapy positioning is an important link in the implementation of radiotherapy planning. In clinical practice, factors such as changes in the position and volume of the target area during treatment due to uncertain daily setup and patient organ movement will bring great errors to the treatment, and even cause irreparable damage to the patient. At the same time, during the process of patients receiving fractionated treatment, the position and shape of the treatm...
