The geometric position indication error of the Veterinary ultrasound system refers to the accuracy of displaying and measuring the actual target size and distance using veterinary ultrasound equipment. In practical applications, the main measurement methods are the vertical geometric position indication error and the horizontal geometric position indication error. This technical parameter refers to the accuracy of measuring the size of lesions in animals, which involves consistency between diagnosis and treatment. The factors that affect this accuracy are related to the sound velocity setting and scanning pattern, and the uniformity of fan-shaped images is inferior to the geometric position accuracy of planar linear array scanning.

The thickness of the ultrasound beam slice for animal use refers to the thickness of the linear array, convex array, and phased array transducers in the direction perpendicular to the scanning plane. The thinner the slice. The clearer the animal ultrasound image, the less it will result in image compression. Generate artifacts. The slice thickness depends on the size and natural frequency of the chip in the short axis direction. Solution: Usually, a focusing sound lens is installed in front of the chip and focusing technology is used in the entire machine.

Contrast resolution of veterinary ultrasound refers to the minimum difference in echo amplitude that can be detected on veterinary ultrasound images. The better the contrast resolution, the stronger the layering of the image, the richer the detail information, and the more delicate and soft the animal ultrasound image. The reasons that affect this factor mainly depend on the frequency bandwidth of the sound signal and the grayscale of the display circuit.

The blind spot of veterinary ultrasound refers to the depth of the nearest echo target that can be recognized by Veterinary ultrasound Equipment. A small blind spot is beneficial for detecting lesions close to the body surface, and this performance mainly depends on the characteristics of the amplifier. In addition, reducing the amplitude of the transmitted pulses entering the amplifier and adjusting the amplifier time constant can also affect the size of the blind spot. However, for testing transducers with water pockets, their blind spots are meaningless.
