Real time monitored control system and method of high strength ultrasonic therapy

Abstract

A real-time system and method for monitoring of high intensity ultrasonic wave therapy is disclosed. The system includes a sync pulse generator, a signal collection arrangement, a B type ultrasonic machine, an ultrasound therapeutic instrument, a computer and a display. The method utilizes intermittent time of ultrasonic wave to transmit sync pulse, while the pulse controlled ultrasonic therapeutic instrument transmits the ultrasonic wave in a intermittent mode meanwhile controls the computer to receive the B type ultrasonic information in intermittent time. Since the output signal sent by the ultrasonic wave machine is in synchronism with the pulse signal and avoids the noise interference of the therapeutic ultrasonic wave, in addition, the therapeutic point position image monitored by the B type ultrasonic wave can display clearly by way of computer. The system and method work under the uniform coordinated sync pulse instruction, realize the noise free real-time monitoring during the ultrasound wave therapeutic process and obtain clear B type ultrasound image.

Description

technical field [0001] The invention relates to a system and method for real-time monitoring of high-intensity therapeutic ultrasonic treatment process, in particular to a system and method for noise-free real-time monitoring of high-intensity ultrasonic treatment process by using a B-ultrasound machine. technical background [0002] Treatment with ultrasonic equipment is a new technology developed in recent years. There are still many problems to be solved in clinical application. One of the problems to be solved is to use B-ultrasound machine to realize noise-free real-time monitoring of the treatment process. High-intensity ultrasonic therapy is to emit ultrasonic waves from the outside to the body, and focus on the treatment area in the body, generate high temperature in the treatment area, and cause coagulation necrosis of the diseased tissue in the treatment area, so as to achieve the purpose of treating diseases. During the treatment process, the treatment point needs...

AI Technical Summary

Problems solved by technology

The monitoring method can be MRI, CT, B-ultrasound machine, etc., but MRI is inconvenient and economical, and the monitoring time of CT is too long, and its radiation is not good for patients. Although B-ultrasound machine can avoid MRI and B-ultrasound as a monitoring method for high-intensity ultrasound therapy The defects of CT, but the B-ultrasound machine also has its inherent disadvantages, that is, the B-ultrasound machine is easily interfered by the high-intensity therapeutic ultrasound, making it difficult to identify the image and difficult to monitor effectively in real time

[0003] There has been a patent disclosure that properly transforming the B-ultrasound machine and combining it with the ultrasonic therapy machine can remove the interference in the treatment area, such as U.S. Patent No. 6,425,867B1, which discloses using the scanning synchronization signal of the B-ultrasound machine Controlling the ultrasonic treatment machine can remove the interference fringes near the treatment area, but the difficulty in implementing this patent lies in the need for internal modification of the B-ultrasound machine, and the noise-free area is limited to a small area near the treatment point

It is extremely unrealistic to transform the B-ultrasound machine at present, which requires the permission and technical support of the B-ultrasound machine manufacturer

At the same time, the small range of noise-free monitoring will bring inconvenience to clinical use, because the noise-free monitoring area described in this patent is related to the average transmission power of the ultrasonic treatment machine. The smaller the acoustic emission power, this shortcoming is especially not suitable for the treatment monitoring of deep diseased tissues
