Abstract

The invention discloses a radiotherapy plan design simulation and three-dimensional dose distribution testing device. The device can accurately determine the spatial positions of points A and B by positioning marking beads and marking bead fixing plates. In X-ray films or CT images, both It can develop accurately, and it is convenient to accurately determine the reference point for dose calculation; by changing the placement position of the dome applicator fixing plate and changing the length of the positioning hole in the uterine cavity applicator fixing plate, the effective lengths of 4 and 6 can be placed respectively. , 8cm uterine cavity applicator, can simulate and design various typical plans for tumor brachytherapy. Through the dosimetry films placed in the uterine cavity source applicator fixing plate and other different positions in the inner cavity through the film fixing plate, the dose distribution of parallel planes within the main range of irradiation of the entire treatment plan with an interval of 1-2mm can be obtained, and the The dose distribution of all planes is compared with the dose distribution of the planned system design, that is, the three-dimensional dose distribution test and verification in space is realized.

Description

technical field

[0001] The invention is used in the field of medical devices, and in particular relates to a radiotherapy plan design simulation and three-dimensional dose distribution testing device. Background technique

[0002] The application of radioactive sources in medical treatment has a history of more than 100 years, and has played an extremely important role in the fight against malignant tumors. At present, in the radiotherapy of tumors, the high-dose-rate miniature iridium-192 radioisotope produced by the reactor has been most widely used. The radioisotope can be made into a columnar radioactive source with an outer diameter of about 1 mm and a length of 4 mm. Welded together with flexible steel wire, driven by a computer-controlled stepping motor, cooperates with the applicator, enters the natural lumen or tissue of the human body, and stays at a specific position in the human body for a specified time according to the planned design , to give a certain radiat...
