Multi-element transducer element selection device and method and ultrasonic stimulation system

Abstract

The invention provides a multi-element transducer element selection device and method and an ultrasonic stimulation system. The ultrasonic stimulation system comprises an image acquisition device which is used for acquiring a lesion tissue region image, and an image processing device which is used for processing the lesion tissue region image to determine the position, size and lesion degree of a lesion tissue. The multi-element transducer element selection device is used for selecting a corresponding element in a multi-element transducer, carrying out delayed adjustment on the phase of an excitation pulse signal to be transmitted by the corresponding element channel, determining the focus depth, setting the parameters of an ultrasonic transmitting sequence, and controlling the multi-element transducer to start according to the focus depth and the transmitting sequence parameters. The selected corresponding element in the multi-element transducer transmits ultrasound to carry out ultrasonic stimulation on the lesion tissue. According to the invention, ultrasound is used to stimulate the lesion tissue of the heart and cerebral vessels; cardiovascular and cerebrovascular diseases are regulated; and the tissue on an ultrasound path is not damaged.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic stimulation, in particular to an array element selection device and method for a multi-element transducer and an ultrasonic stimulation system. Background technique [0002] In my country, with the development of economy and the change of lifestyle and eating habits, the incidence of cardiovascular and cerebrovascular diseases has been increasing, and it has become the leading cause of death. At present, the main treatment methods include drug therapy and interventional therapy. [0003] Objects or biological tissues in the sound field absorb, scatter, and reflect sound waves, and convert the energy of sound waves into physical momentum, and are affected by force, which is defined as ultrasonic radiation force in acoustics. Using ultrasonic radiation force to act on the diseased area of ​​cardiovascular and cerebrovascular diseases, it provides a new means of prevention and treatment f...

AI Technical Summary

Problems solved by technology

Extracorporeal shock wave therapy mainly utilizes the stress effect and cavitation effect of sound waves, and its stimulation depth range and resolution limit its application in the treatment of cerebrovascular diseases

In addition, during the shock wave therapy process, its high energy will cause different degrees of damage to the tissue

Implantable electrical stimulation therapy is an invasive technique, the device and operation are expensive, and there are certain risks of surgical complications, target tolerance, rejection, etc.
