Abstract

The invention discloses a positioning and locating device for radiotherapy and a positioning method of a dynamic target region. A therapy robot has an operating arm, wherein a compact linear electronic accelerator is arranged at one end of an operating arm of the therapy robot, and a secondary collimator is installed at one end of the compact linear electronic accelerator; a robot treatment table is arranged on a corresponding position of a double-image C-arm system, an C-arm sliding rail laser locator is arranged inside the double-image C-arm system, and a left side locator for an C-arm installation space is arranged on a corresponding position at the outer part of the double-image C-arm system. The positioning and locating device provided by the invention is provided with two groups of X-ray image systems, so as to realize binocular imaging; when the C-arm sliding rail rotates and a group of X-ray image systems is started, and CBCT (Cone Beam Computed Tomography) imaging can be realized; according to the positioning method, different imaging ways are adopted for a static target region and a dynamic target region, the rapidity and timeliness of the binocular imaging, the high quality, high definition and image registration of the CBCT imaging can be fully exerted.

Description

technical field

[0001] The invention relates to the field of medical equipment and its positioning method, in particular to a radiotherapy positioning device and a static and dynamic target area positioning method. Background technique

[0002] Radiation therapy is one of the important means of tumor treatment, which is of great significance for improving human health and increasing human life span. Statistics provided by the World Health Organization (WHO) show that among curable cancers, the cure rate of surgery is 22%, the cure rate of radiotherapy combined with surgery is 6%, the cure rate of radiotherapy is 12%, and the cure rate of chemotherapy is only 5%. Visible, radiation therapy is an important technical means of cancer cure. A research report published at the 18th World Health Organization International Anti-Cancer Union Congress stated that the global cancer situation is getting worse, the number of new patients will increase from the current 10 million to 15 mi...
