[0002] At present, the tumor radiotherapy quality inspection product control field needs to accurately measure the radiation dose of each position of the spatial coordinates, and then a finger-shaped ionization chamber is carried by equipment to measure the radiation dose of each position by moving in a certain space. In order to simulate the structure of the human body, it is necessary to simulate the attenuation of the radiation dose in the human body in this space. Since the density of the human body is basically equivalent to water, the overall measurement process needs to move in a water-filled environment to achieve the actual effect of equivalent human treatment. Since the shape and size of tumors vary from person to person, accurate spatial three-dimensional dose distribution needs to be repeatedly corrected in treatment planning, so the measurement position of the rays needs to be more accurate to better achieve the purpose of accurately eliminating tumors without harming healthy organs.
