One of the important indicators of good or bad veterinary B-ultrasound is resolution, which is an important indicator to measure its performance. The resolution of veterinary B-ultrasound diagnostic equipment can be subdivided into axial resolution, lateral resolution and image resolution. Among them, the axial resolution of veterinary B-ultrasound refers to the minimum distance between two point targets that can be distinguished on the plane parallel to the axial direction of the ultrasound beam, and the lateral resolution refers to the minimum distance between two point targets that can be distinguished on the plane perpendicular to the same depth of the ultrasound beam. The image resolution of veterinary B-ultrasound mainly refers to the pixels and clarity of the ultrasound image. In the design of veterinary B-ultrasound diagnostic equipment, only the lateral resolution needs to be considered, because the axial resolution is determined by the veterinary B-ultrasound ultrasound probe, while the image resolution can be improved through a series of means such as veterinary B-ultrasound image processing.

Two important indicators of good or bad veterinary B-ultrasound are detection depth and pulse repetition frequency. The detection depth that can be achieved by veterinary B-ultrasound ultrasound diagnostic instruments is generally determined by the resonant frequency performance of the piezoelectric chip of its ultrasound probe, and the detection depth determines the repetition frequency of the pulse. Therefore, the period of transmitting ultrasonic pulses must be greater than the transit time to ensure that a new ultrasonic pulse is transmitted after the echo signal is received by the veterinary B-ultrasound probe. At present, there are generally three ways to increase the detection depth: reduce the transmission frequency of ultrasound, increase the sensitivity of the ultrasound receiver, or increase the transmission power of ultrasound. However, reducing the transmission frequency of ultrasound will also reduce the lateral resolution of the ultrasound image. Improving the sensitivity of the veterinary B-ultrasound receiver requires the ultrasound diagnostic system to have a sufficiently large gain and extremely low noise. Increasing the transmission power can easily cause damage to the animal being examined. Therefore, increasing the detection depth requires comprehensive consideration of the above factors.
