Problems solved by technology

[0003] In the research on precise radiotherapy technology, many hospitals in China are exploring ways to solve the problem of breathing movement. Typical breathing control systems include Elekta’s active breathing control system (active breathing controlABC) and the US Varian’s respiratory gating system. (respiratory gating system RGS), but its price is expensive, the clinical application conditions are relatively high, and it is difficult to popularize

Embodiment 1

[0016] Such as figure 1 As shown, a breathing control system for precise radiotherapy includes an airbag, an air pump, a control unit, a breathing sensor, a wireless transceiver module in the treatment room, a wireless transceiver module in the control room, a PC terminal and a communication tool. The airbag is installed on the patient's breathing pathway In the process, the airbag is inflated to close the patient's respiratory pathway, and the patient is in a breath-holding state; when the airbag is deflated, the patient's respiratory pathway is released, so that the patient can breathe freely. The sensor is placed in the treatment room. The function of the respiration sensor is to convert the airflow signal of the patient's respiration condition into an electrical signal, and display the respiration waveform after processing. The respiration sensor is a Pneumotach type PowerCube lung function respiration sensor, Pneumotach The type sensor is designed according to the princip...

Abstract

The invention discloses a breathing control system used for an accurate radiation therapy. The system comprises a gasbag, a gas pump, a control unit, a breathing sensor, a treatment-chamber wireless transmit-receive module, a control-chamber wireless transmit-receive module, a PC terminal and a communication tool. The control unit, the breathing sensor and the communication tool are connected to the treatment-chamber wireless transmit-receive module. The treatment-chamber wireless transmit-receive module is connected to the control-chamber wireless transmit-receive module. The control-chamber wireless transmit-receive module is connected to the PC terminal. The control unit comprises a first control unit, a second control unit and a third control unit. The first control unit is connected to the gas pump. The gas pump is connected to the gasbag. The second control unit and the third control unit are connected to the gasbag. The breathing control system used for the accurate radiation therapy can help a patient carry out breathing control so that a purpose of reducing lung tumor migration following human body breathing motion is achieved; treatment accuracy is increased; a clinic application condition is low; and the system is suitable for widespread popularity.

Description

technical field [0001] The invention relates to a breathing control system for precise radiotherapy. Background technique [0002] Malignant tumors are one of the five major causes of death for humans (cardiovascular and cerebrovascular diseases, malignant tumors, respiratory diseases, car accidents, and suicides). In modern treatment, surgery, radiotherapy, and chemotherapy are the three main ways to treat tumors. Radiation therapy for tumors has advantages and disadvantages. During the course of treatment, changes in the position of the tumor target area caused by organ movement, especially respiratory movement, will have a serious impact on the treatment results. If it is not corrected in time, it will cause irradiation deviation, so that the tumor cells receive insufficient irradiation, but the surrounding normal tissues will be damaged due to excessive irradiation. In the research and development of adaptive radiotherapy, Shi Guozhi proposed that precise radiotherapy ...
