Embodiment Construction
[0044] In this embodiment, a method for calculating the dose of photons and electrons under a magnetic field based on the GPU Monte Carlo algorithm is applied in the field of MRIgRT, that is, in the MRI magnetic field environment, the radioactive source passes through complex interactions with the human body model. Energy is deposited in the experimental environment in various organs of the human body model, specifically, as figure 1 As shown, proceed as follows:
[0045] Step 1: Collect data
[0046] Step 1.1. Obtain and process the radiation source data of the radiation therapy accelerator to obtain radiation source information where E represents the source energy, represents the source location, Indicates the source emission direction;
[0047] Step 1.2, obtain the image data of the human anatomy structure of the CT machine or the nuclear magnetic resonance instrument MRI or the positron emission type computed tomography imaging machine PET and reconstruct the human ...
