Dose verification die body model manufacturing method, device thereof and system

Abstract

The invention provides a dose verification die body model manufacturing method, a device thereof and a system, and the manufacturing method comprises the steps: S101, building a three-dimensional model according to the image data of a patient, and generating a dose detector model; S102, forming a space corresponding to the shape of the dose detector model in a patient target area and a dangerous organ of the three-dimensional model to generate a first three-dimensional model, and marking an area associated with the patient target area on the surface of the first three-dimensional model; and S103, cutting the first three-dimensional model to form a second three-dimensional model, performing 3D printing on the second three-dimensional model to obtain a carrier model, assembling the carrier model, and putting a dose detector into the carrier model to form the dose verification die body model. The model and the patient are kept consistent, the influence of external factors is reduced, thedifference between the verification dose and the actual dose of the patient is reduced, accurate instructions are achieved by controlling the dose endangering organs, an incident point, an area and direction of rays are determined in the mode of marking the associated area of the target area, and dose irradiation is facilitated.

Description

technical field [0001] The invention relates to the field of radiotherapy dose verification, in particular to a method, device and system for making a dose verification phantom model. Background technique [0002] At present, the dose verification methods in the process of tumor radiotherapy include dose verification, two-dimensional dose verification and three-dimensional dose verification. The implemented technology can verify the dose required for radiotherapy through the verification tools of the accelerator and third-party verification tools. [0003] However, the dose verification methods implemented in the existing technology are to place different probes in the standard universal phantom to measure the dose, and then use the three-dimensional reconstruction method to import the dose into the patient image with software, and the dose can be obtained by secondary calculation , because of the difference in the general phantom, the volume of the probe, the sensitivity, t...

Problems solved by technology

[0003] However, the methods used in the dose verification of the existing technology are to place different probes in the standard universal phantom to measure the dose, and then use the three-dimensional reconstruction method to import the dose into the patient image with software, and the dose can be obtained by secondary calculation , because of the differences in the general phantom, the volume of the probe, the sensitivity, the external environment and human factors, it will inevitably lead to differences between the results and the actual patient treatment dose
