Transmitting module of ultrasonic diagnostic device

Abstract

The invention discloses an emission module for ultrasonic diagnosis equipment, comprising an emission control unit and a transmit element connected with the emission control unit; wherein, the emission control unit is used for generating control signals transmitted to the transmit element; the transmit element is used for transmitting pulse waveform which comprises at least five different levels according to the received control signals. The invention has the advantages of forming various forms and types of wide pulse waveforms, ensuring the transmitting energy of the emission module, and increasing the acquisition depth of human tissues by adopting different pulse waveforms which comprises at least five different levels; moreover, the formed single pulse or bipolarity pulse has an obvious echo characteristic, and reduces the probability greatly that the echo signal is submerged by noise.

Description

technical field [0001] The invention relates to the technical field of ultrasonic diagnosis, in particular to a transmitting module of an ultrasonic diagnostic instrument. Background technique [0002] In the ultrasonic system in the prior art, the pulse waveform generated by the switching pulse generator is transmitted to the ultrasonic transducer. In order to improve the longitudinal resolution of the ultrasonic system on human tissue, it is usually required to use narrow-width pulses; however, narrow-width pulses bring about a reduction in transmitted energy, resulting in a reduction in the detection depth of human tissue by the ultrasonic system. [0003] The transmitting pulse of the ultrasonic system in the prior art adopts a continuous two-level or continuous three-level waveform, and can only generate simple unipolar or bipolar pulses. This transmitted pulse is converted into an ultrasonic signal by the transducer and enters the human tissue, and the characteristics...
