Problems solved by technology

[0002] At present, traditional neuromodulation methods generally use a single frequency and a single waveform excitation, such as sine wave or square wave excitation, but the excitation signal of a single frequency cannot give full play to the performance of the ultrasonic transducer
Moreover, the current equipment hardware uses a method similar to a direct digital frequency synthesizer to generate the excitation signal, which is less flexible

Embodiment Construction

[0044] At present, medical ultrasound technology has been widely used in clinical diagnosis and treatment. Ultrasound diagnosis mainly uses ultrasound echoes to obtain imaging information of tissues, and provides necessary diagnostic references for clinicians. Ultrasound therapy uses the mechanical effect, thermal effect and cavitation effect of ultrasound to treat diseases. Specifically, it can be divided into high-dose ultrasonic thermal ablation technology and low-dose ultrasonic regulation technology. High Intensity Focused Ultrasound (HIFU) is a typical ultrasonic thermal ablation technology. HIFU can penetrate tissues and reach the set target area to destroy tumors in the body, and finally absorb the destroyed tumors through the body's own immune system , to achieve the effect of non-invasive treatment. The main applications of low-dose ultrasound therapy are: ultrasound vascular thrombolysis, ultrasound-based opening of the blood-brain barrier, and ultrasound neuromod...

Abstract

The embodiment of the invention provides an ultrasonic excitation device, method and system. The ultrasonic excitation device comprises a waveform generator, a power amplifier, and an ultrasonic transducer array. The waveform generator is used for obtaining the ultrasonic excitation parameters of all channels, and then generating a waveform excitation signal of each channel according to the ultrasonic excitation parameters. The power amplifier is electrically connected with the waveform generator, and is used for carrying out the power amplification of the power amplification, and generating ahigh-voltage drive signal and inputting the high-voltage drive signal into the ultrasonic transducer array. The ultrasonic transducer array is used for generating ultrasonic waves on the corresponding elements according to the high-voltage drive signal, and comprises a plurality of elements, wherein each element is corresponding to one channel. Therefore, the device can give full display to the performances of the ultrasonic transducers, and obtains the better ultrasonic mechanical effect and thermal effect.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to an ultrasonic excitation device, method and system. Background technique [0002] At present, traditional neuromodulation methods generally use a single frequency and a single waveform excitation, such as sine wave or square wave excitation, but the excitation signal of a single frequency cannot give full play to the performance of the ultrasonic transducer. Moreover, current device hardware mostly adopts a method similar to a direct digital frequency synthesizer to generate an excitation signal, and this method is less flexible. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an ultrasonic excitation device, method and system, which can flexibly configure the ultrasonic excitation parameters of each channel to generate excitation signals of arbitrary wa...
