Method for manufacturing physical compensation lead brick for two dimensional radiotherapy

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 b
