Embodiment Construction
[0020] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, the particle implantation treatment plan design method provided by the present invention includes the following steps:
[0022] Step 1: Determine the particles in all possible positions, and calculate the average dose of each particle to the target area and OARs, which is recorded as set S.
[0023] Step 2: Sort the particles in the set S according to the arbitration criterion. The arbitration criterion Cs is defined as:
[0024] C s = w 1 × OAR 1 ‾ + w 2 × OAR 2 ...
