Real-time performance of veterinary B-ultrasound. The real-time performance of B-ultrasound diagnostic equipment requires that the ultrasound image can be updated in time when the B-ultrasound probe is moved. This technology is determined by the frame rate of veterinary B-ultrasound. The higher the frame rate, the better the real-time performance. This technology, combined with ultrasound image freezing technology, provides doctors with a lot of useful diagnostic information for clinical diagnosis. To achieve this requirement of real-time display, the B-ultrasound diagnostic equipment used must be able to achieve rapid scanning of the sound field and have sufficient frame rate. Generally speaking, a system with a frame rate of more than 30Hz can be considered a real-time system.

Attenuation and depth compensation of veterinary B-ultrasound system. When the ultrasonic wave emitted by veterinary B-ultrasound propagates in the animal body, the loss of ultrasonic energy mainly comes from absorption attenuation and scattering attenuation. When a 2.5MHz veterinary B-ultrasound probe is used to emit ultrasound to detect soft tissue at a depth of 20cm, the total attenuation can reach 100dB, and the echo signal decays approximately according to the exponential law. In order to make the medium interface for long-distance inspection also clearly displayed, it is necessary to perform depth compensation or time gain compensation on the received echo to make it more amplified.

The ease of use of veterinary B-ultrasound mainly refers to the multi-function of veterinary B-ultrasound diagnostic equipment (such as organ imaging, blood flow imaging, etc.) and the automation and intelligence of recording and processing of various data, which requires veterinary B-ultrasound diagnostic equipment to work in a variety of acoustic detection methods and be equipped with a variety of veterinary B-ultrasound probes. These are all measurement indicators in addition to resolution, detection depth, and pulse detection repetition frequency, which need our attention.
