Abstract

The invention relates to the technical field of human body internal irradiation detection, and discloses a human body internal irradiation dose detection method, device and system and computer equipment. The invention creates and provides a human body internal irradiation dose detection scheme based on a neural network algorithm, which can give consideration to differences of forms and organ volumes among individuals, and can ensure that a human body tissue equivalent model with relatively high precision can be established and accurate positioning of organ positions can be realized due to the fact that human body CT data is used as a support. And by defining the parameters of the internal irradiation radioactive source, targeted radiation detector efficiency calibration can be carried out on each patient when the internal irradiation dose is directly measured, so that the calculation precision of the internal irradiation dose is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of radiation detection in the human body, and in particular relates to a method, device, system and computer equipment for detecting radiation dose in the human body. Background technique [0002] In a nuclear accident, radioactive substances may be released into the surrounding environment on a large scale, and ultimately have adverse effects on the human body. After radionuclides are ingested into the body, they will be deposited and retained in the tissues or organs to which they are compatible, producing radiation doses and causing harm until they are completely excreted. Radionuclides can enter the body through such as ingestion, inhalation, skin or wound, etc., resulting in uneven distribution in the human body, and mainly deposited in specific organs of the human body, such as the lungs, thyroid and stomach. [0003] For common γ-radiation substances, due to the long range of rays, there is not much ...
