Respiratory gating equipment used for tumor radiotherapy

Abstract

The embodiment of the invention discloses respiratory gating equipment used for tumor radiotherapy. The equipment comprises an eyeglass shell body, a respiration detection pipeline, a display screen, a lens and a control chip are arranged in the eyeglass shell body, and the control chip is connected with a position sensor through a wire; the position sensor is located outside the eyeglass shell body, a flow sensor is arranged at the upper end of the respiration detection pipeline, a respiration pipeline is connected with the lower end of the respiration detection pipeline, and a respiration pipe mouth holding device is connected with the respiration pipeline. According to the equipment, a collection sensor for respiratory movement is miniaturized and integrated into video glasses, provides convenience for use of the respiratory gating equipment and can collect air flow data and displacement data of the thorax and the abdomen during respiration to achieve precise judgment of the tumor position, in combination with guidance for respiration of a patient through multi-mode respiration signal curves played by the display screen, it can be judged that the corresponding respiration mode followed by the patient achieves the shortest consumed time and the minimum respiratory amplitude, and therefore, consumed treatment time can be shortened.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of tumor radiotherapy, and in particular to a respiratory gating device for tumor radiotherapy. Background technique [0002] The following two respiratory gating systems currently on the market for radiotherapy are represented and have mature experience in use. [0003] Method 1: Active breathing control device [0004] The breathing monitoring method represented by Elekta's active breathing control system can reduce the degree of physiological swimming caused by breathing in lungs, liver, breast and other organs, thereby improving the accuracy of treatment. The device detects the breathing movement of the patient, and establishes the relationship between the amount of gas in the lungs and the position of the tumor through the sensor to detect the amount of gas in and out. During positioning and treatment, the patient is prompted to adjust his breathing by video or technician voice. W...

Problems solved by technology

[0010] To this end, the embodiment of the present invention provides a respiratory gating device for tumor radiotherapy, which miniaturizes the acquisition sensor of respiratory motion and integrates it into video glasses, uses the video glasses to guide the patient's breathing, and then monitors the respiratory movement The air flow data and the displacement data of the chest and abdomen are collected, and it is judged which breathing pattern the patient follows will take the shortest breathing time and the breathing amplitude is the smallest, so as to solve the problem of low cooperation due to the complicated operation of the equipment and the difficulty in understanding the patient in the prior art. Training is required to use, the training can only be done in a specific room due to the large volume of the machine, the location of the tumor is inaccurately determined due to the single method of breathing detection, and the treatment time is long due to the incorrect breathing pattern of the patient
