How is veterinary B-mode structured

The beam combiner is called the front end of the veterinary ultrasound, and the scan converter is called the rear end of the veterinary ultrasound. The back end of the veterinary ultrasound system is always digital, so-called digital scan conversion DSC, and the front end of the veterinary ultrasound system can be either a digital front end or an analog front end.
When the veterinary ultrasound has a digital front end, its signal processing part is optionally digital signal processing, and the scan conversion is originally digital, so such a veterinary ultrasound is called an all-digital veterinary ultrasound .

Beam synthesis is simply delay summation. Delay is the need to control the direction and focus of the sound beam. It is the essence of the front end of the veterinary B-ultrasound, or even the essence of the entire veterinary B-ultrasound. Delay accuracy is one of the most important indicators of veterinary B-mode ultrasound, and it is the core element that determines the sound beam quality and even the image quality. The complexity of the delay becomes more prominent in the occasion of receiving dynamic focusing. At this time, the delay must dynamically change in real time as the depth of reception increases.
The method of delay can be divided into two categories: analog part. Their working relationship is: first, the ultrasonic pulse is transmitted by the transmitting circuit, and then loaded on the probe through the probe interface circuit; after the probe receives the echo signal, it returns to the receiving amplifier circuit through the probe interface circuit.
