The beamformer is called the front-end of the Veterinary Ultrasound, and the scanning converter is called the back-end of the veterinary ultrasound. The backend of veterinary ultrasound is always digital, which is called digital scanning to transform DSC, while the frontend of veterinary ultrasound can be either digital or analog.

When a veterinary ultrasound has a digital front-end, its signal processing part is inevitably digital signal processing, and scanning transformation is already digital. Therefore, such veterinary ultrasound is called a fully digital veterinary ultrasound.

Simply put, beamforming is the sum of delays. Delay is necessary for controlling the direction and focus of the sound beam, and is the essence of the front-end of veterinary ultrasound, and can even be said to be the essence of the entire veterinary ultrasound. Delay accuracy is one of the most important indicators of veterinary ultrasound, and it is the core element that determines the quality of sound beams and even image quality. The complexity of delay becomes more prominent in the case of receiving dynamic focusing, where the delay needs to dynamically change in real time as the receiving depth increases.

The methods of delay can be divided into two categories: simulation part. Their working relationship is as follows: firstly, ultrasound pulses are emitted by the transmitting circuit, and then loaded onto the probe through the probe interface circuit; After receiving the echo signal, the probe returns to the receiving amplification circuit through the probe interface circuit.
