Abstract

The invention provides a hemispherical retractable 3D optical fiber accelerator morning inspection instrument, which can detect the performance index of a linear accelerator and belongs to the field of accelerator detection. A hemispherical retractable 3D fiber optic accelerator morning inspection instrument provided by the present invention is divided into two parts, one part is a receiving device, and the other part is a data detection and acquisition device, which are connected through an optical fiber bundle. Eight arc-shaped slides are evenly distributed on the circular base plate of the receiving device, and a moving head is installed on the slides. After the optical fiber probe passes through the moving head, it can move arbitrarily and be fixed on the arc-shaped track. The other ends of all optical fiber probes form an optical fiber bundle through the circular hole on the base plate, and are connected with the detection and collection device. The detection and acquisition device is composed of a light intensity detector and a data acquisition card. The novel optical fiber accelerator morning detector provided by the present invention has a simple structure, light and handy volume, can detect dose output in three-dimensional space, can display measurement results in real time during work, and can be applied in different special fields such as underwater.

Description

technical field

[0001] The invention provides a hemispherical retractable 3D optical fiber accelerator morning inspection instrument, which belongs to the field of accelerator detection.

[0002] technical background

[0003] According to research data, the prevalence and mortality of tumors in the world's population are increasing year by year, nearly doubling compared to ten years ago. Therefore, it is very necessary to attach great importance to the treatment of tumors. For the treatment of tumors, the most effective method at present is radiation therapy, which uses high-energy X-rays to irradiate tumor cells. Accurate radiotherapy technology can not only give sufficient and precise irradiation dose to the tumor area, effectively control the onset of tumor, but also reduce the irradiation dose to surrounding normal tissues and organs, and reduce the radiation complications of normal tissues. Under the condition of ensuring safety and effectiveness, in order to accuratel...
