Problems solved by technology
Although three-dimensional intensity-modulated radiation therapy has a good therapeutic effect, its treatment cost is high. At present, it is mainly equipped in a small number of powerful medical institutions
The existing two-dimensional radiotherapy equipment does not have the intensity modulation function to adjust the intensity of the radiation field, which directly affects the therapeutic effect of two-dimensional radiotherapy, which is not conducive to the poor patients at the grassroots level to obtain good radiotherapy Effect

The invention discloses a method for manufacturing a physical compensation lead brick for two dimensional radiotherapy. The method includes the following steps: 1. acquiring a corresponding patient'sradiotherapy data through a radiotherapy plan system; 2. based on the acquired radiotherapy data, determining design parameters of the physical compensation lead brick; 3. based on the design parameters, manufacturing a physical compensation lead brick for 2 dimensional radiotherapy in the form of 3 dimensional printing; 4. positioning and verifying the manufactured physical compensation lead brick; and if the physical compensation lead brick passes the verification, installing the physical compensation lead brick on a block pallet rack of a 2 dimensional radiotherapy device for performing intensity modulated radiotherapy. According to the invention, the method is simple, easy, feasible, efficient and economical, and the method can produce guarantee an accurate and reliable molding quality. The manufactured lead brick can be efficiently applied to 2 dimensional clinic radiotherapy, can achieve intensity modulated radiotherapy of a 2 dimensional radiotherapy device in a much more reliable and economic economical manner, can increase the effects of 2 dimensional radiotherapy in an economical, stable and reliable manner, and has excellent practicality.
Description
technical field [0001] The invention relates to a manufacturing technology of a physically compensated lead block used in medical operations, in particular to a method for manufacturing a physically compensated lead block used in two-dimensional radiotherapy. Background technique [0002] Radiation therapy is a kind of local treatment method that uses radiation to treat tumors, and it has become one of the main means of treating malignant tumors. Throughout the development history of radiation therapy, it has developed from the initial two-dimensional radiation therapy to the current mainstream three-dimensional intensity-modulated radiation therapy. [0003] Three-dimensional intensity-modulated radiation therapy is an intensity-modulated radiation therapy technique with high treatment accuracy, good treatment effect and less normal tissue damage. The shape and the specific anatomical relationship between important organs and the target area adjust the intensity of the rad...
