Electropult of ultrasonic diagnosis equipment

Abstract

The invention discloses a transmitting device of an ultrasonic diagnostic equipment, including a transmitting control unit and a transmitting drive unit which is connected with the transmitting control unit, the transmitting control unit is used for the output of the Barker code pulse signal, the transmitting drive unit is used for amplifying the input Barker code pulse signal and the output of the high-voltage Barker code pulse signal. The transmitting device of the ultrasonic diagnostic equipment of the invention adopts the Barker code rather than the simple pulse as the incentive signal of an ultrasonic sensor, as the Barker code has the nature of an acute autocorrelation function, the higher signal-to-noise ratio is obtained and the resolution of the ultrasound image is improved; at the same time, the invention adopts the single transmission method, which also ensures the high frame rate of the ultrasound image.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnostic equipment, in particular to a transmitting device for ultrasonic diagnostic equipment. Background technique [0002] In the ultrasonic diagnostic equipment of the prior art, the emission of ultrasonic waves generally uses high-voltage pulses to excite piezoelectric elements, thereby generating ultrasonic waves of a certain frequency into the human body, and utilizing the discontinuity of the internal acoustic resistance of the human body to pass the reflected sound wave energy through The sensors receive and then pass on to each receive channel of the system respectively. These receiving channels first amplify the signals from the sensors, then digitize them, and then extract two-dimensional tissue information and blood flow Doppler information through a series of processing such as beamforming. [0003] As shown in Figure 1, the electronic focusing of the sound beam is realized by ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a transmitting device for ultrasonic diagnostic equipment, which overcomes the problem of ultrasonic image frame frequency and ultrasonic image resolution when the ultrasonic diagnostic equipment transmitting device of the prior art transmits unipolar pulses multiple times to form a frame of ultrasonic image. Both are relatively low defects, and when a frame of ultrasonic image is formed by transmitting bipolar pulses multiple times, the frame frequency of the ultrasonic image is low and the circuit is complicated
