Example Embodiment

[0046] It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.

[0047] In the prior art, the experimental method is used to measure the radiation dose at different positions of the three-dimensional tank to represent different organ radiation doses. The method of using the three-dimensional water tank represents the organism is relatively simple, and the value obtained by the measurement does not real reflect the actual organ radiator. .

[0048] Refer figure 1 As shown, a flow schematic of a flow of particle external irradiation experimental animal organ radiation dose evaluation method according to an embodiment of the present invention. The method can be performed by a device, which can be implemented by software and / or hardware.

[0049] In the present embodiment, the particle external irradiation experimental animal organ radiation dose assessment method includes S1 ...

Abstract

The invention relates to the field of radiation protection, and provides an animal organ radiation dose evaluation method for a particle external irradiation experiment. The method comprises the steps of obtaining an organ dose conversion factor by utilizing an experimental animal digital model and particle transportation simulation calculation, and then measuring air kerma kinetic energy to perform organ radiation dose evaluation. The problem that the organ dose is difficult to directly measure is solved, and the technical effect of improving organ dose evaluation convenience and accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of radiation protection, and relates to a method, a device, an electronic device and a computer-readable storage medium for evaluating the radiation dose of an animal organ in a particle external irradiation experiment. Background technique [0002] With the in-depth study of the biological effects of ionizing radiation, researchers have found that the average dose of the whole body cannot meet the needs of the evaluation of biological effects; and the relationship between the biological effects of ionizing radiation and the dose is an important theoretical basis for radiation protection, that is, the medical treatment of radiation damage. Therefore, researchers usually use experimental animals (mice, rats, monkeys, etc.) to study the relationship between organ radiation dose and biological effects under particle external irradiation conditions. However, since radiation detectors cannot be placed directly in...
