Radioactive ray monitoring and treating system

Abstract

The invention discloses a radioactive ray monitoring and treating system. The radioactive ray monitoring and treating system comprises a location monitoring device, a movement monitoring device, a treating monitoring device, a data processing device and an accelerator control device. The location monitoring device is used for obtaining location data of a patient by monitoring a magnetic field of a body surface location corresponding to an area where tumors of the patient are located; the movement monitoring device is used for obtaining location data of a target area and an organ at risk by monitoring a magnetic filed of an in-vivo location corresponding to an area where the tumors and / or the organic at risk of the patient is located; the treating monitoring device is used for obtaining blade location data by monitoring a magnetic field of blade locations of a multi-blade collimator of an accelerator; the data processing device is used for judging whether the patient location data, the location data of the target area and the organ at risk and the blade location data all met preset location requirements or not and sending out an instruction used for controlling the accelerator control device to start or stop irradiation according to a judgment result; the accelerator control device is used for starting or stopping radiation treatment according to the instruction sent out by the data processing device. According to the radioactive ray monitoring and treating system, a magnetic localization mode is adopted, and the accuracy of radiation treatment is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a radiation monitoring and treatment system. Background technique [0002] With the popularization and application of intensity-modulated radiotherapy technology, radiotherapy has entered the era of precision radiotherapy. Intensity-modulated radiotherapy technology solves the problem of conformal treatment of static target volumes and greatly improves the accuracy of radiotherapy. However, the movement of the body's own organs will lead to unpredictable target movement, which makes intensity-modulated radiotherapy face the risk of dose distribution deviating from the target region. Radiotherapy technologies such as real-time positioning and tracking treatment are needed to ensure accurate treatment of the moving target region. [0003] At present, the real-time positioning and tracking treatment systems used clinically include two types: X-ray imaging positioning system and non...

Problems solved by technology

Its biggest problem is the uncertainty of the prediction of the movement of the target area by the movement of in vitro markers or the change of vital capacity, which may lead to the failure of the prediction

[0006] In addition, it is the correct idea to combine multiple methods to achieve complementarity, but the system is complex, difficult to apply, and takes longer. For example, Accuray's CyberKnife synchronous tracking system uses X-ray imaging and infrared detector systems to Real-time monitoring, but the treatment process is often suspended due to model failure, and the entire treatment process is time-consuming

[0007] Real-time monitoring of the movement of the target area and changes in the position of the body surface through the above-mentioned technology has shortcomings in real-time and accuracy, and the treatment takes a long time, and the X-ray imaging positioning method will also increase the patient's exposure dose
