Timing synchronizer for medical circular accelerator

Abstract

The present invention discloses a timing synchronizer for a medical circular accelerator. The timing synchronizer comprises a master control computer, a database server, a local area network host, a plurality of PXIe partial nodes and a plurality of optoelectronic isolation devices. The master control computer, the database server and all the PXIe partial nodes all access the local area network, the PXIe partial nodes are respectively connected with the optoelectronic isolation devices, and the parameters of the clock channels and the triggering channels on the PXIe partial nodes are arranged through the master control computer. The timing synchronizer for the medical circular accelerator selects a reconfiguration I / O module, and establishes the I / O device of user customization; the customization device is large in the number of the channels, fast in the event response speed and simple in system function upgrading and extension; and moreover, the power supplies of each channel unit of an optoelectronic device and an electro-optic device are independent to ensure the independence and communication of the timing synchronizer and peripheral devices.

Description

technical field [0001] The invention relates to the technical field of medical application of timing synchronization technology, in particular to a timing synchronization device for a medical cyclotron. Background technique [0002] Malignant tumors are the greatest enemy of human health. In recent years, malignant tumors have shown a rising trend. Researchers have developed proton therapy equipment by using the positively charged particles—protons to generate Bragg peaks (Borrag peaks) to kill cancer cells, which have been evaluated by the high-energy physics and medical circles as the best curative effect, The treatment with the fewest side effects. A medical cyclotron is one such device that generates protons and uses them in the treatment of malignant tumors. The medical cyclotron itself is a precise device, and includes many subsystems such as vacuum, low temperature, power supply, and transportation. working and eventually used in proton therapy. [0003] Through t...
