Movement detection system and method

Abstract

The present invention relates to the medical technology field, and provides a movement detection system. The system comprises a controller, a displacement calculation module, a position sensor and an alarm module. The position sensor is fixedly arranged on a target object and configured to record the position of the target object and send position data to the displacement calculation module; the displacement calculation module is connected with the position sensor and the controller and configured to receive the position data transmitted by the position sensor, calculate the displacement and transmit the displacement data to the controller; and the controller connected with the displacement calculation module and the alarm module and configured to perform comparison analysis of the received displacement data and theoretical data and send control signals to the alarm module; and the alarm module connected with the controller and configured to receive the control signals of the controller and perform execution. The movement detection system and method greatly improve the movement precision of a mobile treatment bed and other medical devices and ensure the patients' treatment effect to the greatest extent.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a movement detection system and method. Background technique [0002] In the field of medical technology, when using medical devices to diagnose and treat patients, it is often necessary to accurately position the medical devices, especially in clinical radiotherapy, using a medical mobile treatment bed to support the patient so that the patient's lesion is located within the radiation range , the mobile treatment bed is used in conjunction with the radiation generator. The radiation beam emitted by the radiation generator irradiates the lesion from multiple directions. The accuracy of the movement of the mobile treatment bed directly affects the irradiation of the patient's lesion, which may lead to recurrence or complications of the patient's disease. increase, thereby affecting the therapeutic effect. [0003] In the prior art, a scale is usually set on the mobile treatment ...

[0002] In the field of medical technology, when using medical devices to diagnose and treat patients, it is often necessary to accurately position the medical devices, especially in clinical radiotherapy, using a medical mobile treatment bed to support the patient so that the patient's lesion is located within the radiation range , the mobile treatment bed is used in conjunction with the radiation generator. The radiation beam emitted by the radiation generator irradiates the lesion from multiple directions. The accuracy of the movement of the mobile treatment bed directly affects the irradiation of the patient's lesion, which may lead to recurrence or complications of the patient's condition increase, thereby affecting the therapeutic effect

[0003] In the prior art, a scale is usually set on the mobile treatment couch, and the movement displacement of the treatment couch is detected by visual inspection. Therefore, the movement control precision of the treatment couch is low, and the degree of automation of the movement detection is low, so it is impossible to automatically judge whether the treatment couch moves. correct

In addition, in the field of medical equipment motion control, there are still many medical equipment, like the above-mentioned treatment bed, which have the problems of low precision of motion detection and low degree of automation
