Cancer therapy system based on cyber knife

Abstract

The invention provides a cancer therapy system based on a cyber knife. The cancer therapy system comprises a robot projection system, a real-time image tracking and positioning system, an infrared synchronous breath tracking system, an automated therapy bed and an intelligent therapy plan system. The robot projection system comprises a mechanical arm and a linear accelerator, the real-time image tracking and positioning system comprises two thousand volts X-ray infrared cameras and corresponding non-crystal digital video detectors; the infrared synchronous breath tracking system is composed of three infrared cameras installed on a ceiling and three infrared diode generators fixed on a breath tracking waistcoat; the automatic therapy bed is designed based on a PID adjustment controller and can freely adjust for five degrees of freedom; the intelligent therapy plan system is used for providing comprehensive therapy design and therapy scheme. The therapy system can achieve accurate positioning of a movable cancer, and reduces harm to human healthy organs while improving therapy accuracy.

Description

technical field [0001] The invention relates to a medical device, in particular to a cyberknife-based tumor treatment system. Background technique [0002] Radiation therapy is the main treatment for cancer. It kills cancer cells by damaging their DNA with high-energy rays. However, while radiation therapy kills cancer cells, it also damages nearby organs and produces unpredictable side effects. Tumors move with human breathing, so the radiation field must have a larger range to ensure that the tumor can receive enough radiation dose, but this increases the toxic damage to healthy tissues. Therefore, improving the accuracy of radiation therapy and reducing the damage to healthy organs of the human body are key issues that must be solved in the field of tumor radiation therapy. [0003] The Cyberknife treatment system is a "surgical" process without blood, pain, and anesthesia. Cyberknife is an excellent choice for patients who do not want to undergo surgery or for lesions ...
