Problems solved by technology

This method can effectively measure intensity-modulated and three-dimensional conformal radiotherapy doses, but since they are all standard measurement components, the measurement conditions cannot be freely defined according to the patient's actual anatomical structure, contour shape, and tumor anatomical structure, so the measurement results will inevitably lead to Not completely accurate, that is, the actual radiation dose and dose distribution of the tumor target area cannot be obtained

Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 A flow chart of a method for radiotherapy dose measurement method according to an embodiment of the present invention is schematically shown. Such as figure 1 As shown, the method includes:

[0025] Step S101: Carry out three-dimensional modeling on the measurement target, and obtain the three-dimensional model of the measurement target.

[0026] According to the patient's condition and anatomical structure, the radiotherapy dose measurement target is selected, and the measurement target is selectively modeled to outline a three-dimensional model of the measurement target. When modeling the measurement target, the medical image is usually acquired through positioning first, so as to draw each part of the measurement target into a three-dimensional thin-layer hollow shell component consistent with the actual shape according to the med...

Abstract

The invention discloses a radiotherapy dose measurement method, which comprises the steps of acquiring a measurement target according to requirements, performing three-dimensional modeling on the measurement target, and obtaining a three-dimensional model of the measurement target; performing 3D printing on the three-dimensional model, and filling the printed three-dimensional model with a material; performing irradiation in a mode of simulating a human body model according to the filled three-dimensional model; processing the irradiated body model, and measuring the exposure dose. The method disclosed by the invention can perform 3D personalized radiotherapy dose measurement according to requirements, so that the anatomical structure, the profile and the tumor anatomical structure of the human body are simulated to the maximum extent, and the measured exposure dose is closer to an actual value, thereby providing more valuable and more reliable experimental reference for implementation of a radiotherapy plan, and providing guarantee for ensuring the success rate of the radiotherapy plan.

Description

technical field [0001] The invention relates to the technical field of radiotherapy, in particular to a radiotherapy dose measurement method. Background technique [0002] Radiation therapy (i.e. radiotherapy) is one of the three major means of treating tumors at present. It refers to a treatment method that irradiates tumors with rays of various energies to inhibit and kill cancer cells. Since radiation destroys and kills tumor cells, it also has a destructive effect on surrounding normal tissue cells, so the goal of radiotherapy is to increase the radiation dose of the tumor target area as much as possible, and at the same time reduce the radiation dose of the surrounding tissues and organs as much as possible. Exposure dose. Therefore, it is of great significance to obtain the irradiation dose of the patient's tumor target area and surrounding tissues and organs to improve the control rate of the tumor and reduce the radiation of radiotherapy. [0003] At present, the r...
