Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0041] In order to facilitate the understanding of the technical solution of t...

Abstract

The invention relates to a device and method used for remotely measuring a residual dose in a proton therapy system. The device mainly comprises a mobile measurement platform, a foldable and scalablesupport arm group and a Gamma ray dose detector; the mobile measurement platform comprises a platform main body carrying a power supply as well as moving wheels; the foldable and scalable support armgroup is formed by connecting a base on the platform main body with multiple foldable arms; a location or / and a detection distance of a to-be-measured point are determined by utilizing a photographicapparatus; the Gamma ray dose detector is arranged at a movable end of the support arm group, and a power line connected with the Gamma ray dose detector as well as a signal line are mounted in each foldable arm. The device provided by the invention has the effect of accurately measuring a residual dose rate of each therapy room in the proton therapy system.

Description

technical field [0001] The invention relates to the technical field of proton therapy, in particular to a device and method for remotely measuring residual dose in a proton therapy system. Background technique [0002] Proton therapy is a new type of radiotherapy technology with broad application prospects and obvious curative effect on a variety of cancers. At present, there is an upsurge in the research and development of proton therapy systems in China. As positively charged particles, protons enter the human body at a very high speed. Due to their high speed, the chance of interacting with normal tissues or cells in the body is low. When they reach a specific part of the cancer cell, the speed gradually decreases and stops. Release the maximum energy and generate Bragg peak (Borrag peak) to kill cancer cells while effectively protecting normal cell tissues. Because proton therapy has the characteristics of strong penetration, good dose distribution, high local dose, les...
