Problems solved by technology

[0006] In order to meet the above requirements, in the prior art, the usual practice is to manually measure the surface temperature rise of the transducer with an external device such as a thermometer. This measurement method wastes labor costs, and at the same time, the measurement results are not very accurate.

Embodiment Construction

[0052] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0053] During the working process of the transducer, the electrical signal emitted by the ultrasonic transducer array element is converted into an acoustic signal. During this process, corresponding heat energy is generated, and the heat energy is further diffused to the surface of the transducer through the matching layer and the lens. .

[0054] Such as figure 1 as shown, figure 1 An ultrasonic transducer control method provided in an embodiment of the present invention, the method includes:

[0055] The surface temperature rise of the transducer is obtained according to the transducer thermal model.

Abstract

The invention provides an ultrasonic transducer control method and system. The method comprises: acquiring transducer surface temperature rise parameters, including: heat transfer coefficient, transmitting waveform coefficient, scanning coefficient, power supply transmitting voltage, and transmitting pulse repetition frequency; acquiring a transducer thermal model according to the transducer surface temperature rise parameters; the transducer thermal model is represented by a following formula; wherein deltaT represents the transducer surface temperature rise, kappa represents the heat transfer coefficient, phi(Waveform) represents the transmitting waveform coefficient, zeta(ImageAngle, F-number) represents the scanning coefficient, Vrms represents root-mean-square voltage of power transmission, and PRF represents the transmitting pulse repetition frequency. In the ultrasonic transducer control method and system of the invention, surface temperature rise of an ultrasonic transducer is automatically monitored according to current state of the ultrasonic transducer, meanwhile the surface temperature rise of the transducer can be precisely controlled according to monitoring results, and further, ultrasonic image quality is improved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and in particular relates to an ultrasonic transducer control method and control system. Background technique [0002] Ultrasound equipment has become one of the most widely used diagnostic tools in clinical practice because of its non-invasiveness, real-time performance, convenient operation, and low price. [0003] Ultrasonic transducer is a key component of ultrasonic equipment, which is an energy converter used to convert alternating electrical signals into acoustic signals or convert acoustic signals in the external sound field into electrical signals within the ultrasonic frequency range; When the transducer is in the transmitting state, it converts electrical energy into mechanical energy, and then converts the mechanical energy into acoustic energy; in practical applications, it converts electrical signals into sound waves and propagates in the tissue to be tested; when the tra...
