Portable veterinary cattle ultrasound 3.5MHZ convex array probe scanning ultrasound diagnostic instrument high configuration        1.1 Features .The instrument uses microcomputer control and digital scan converter (DSC), adopts digital beamforming (DBF), real-time dynamic aperture imaging (RDA), real-time dynamic sound velocity traversal (DRA), real-time point-by-point dynamic receive focusing (DRF) and other technologies The image of the whole machine is clear, stable and high resolution. . Image grayscale 256 levels. .16 color pseudocolor. .It can realize real-time, freezing, storage, recall and large-capacity movie playback; it has the functions of multi-level scanning depth, scanning angle, filtering, frame correlation coefficient adjustment, focus number, focus position adjustment and so on. . Date, clock display, backfat distance measurement. .The combination of AC adapter and built-in lithium-ion rechargeable battery provides a power saving mode, which makes the battery last longer. .The device consists of the host and the probe. Standard CXA60R/3.5MHz convex array, 1.2 Scope of application It is suitable for animal diagnosis such as pigs, horses, cattle, sheep and donkeys. product Display size: 8 inches Image grayscale: 256 levels Image storage: 64 frames Filter: 0-192dB (adjustable range 64- 192dB) Movie playback: ≥400 frames Scanning depth adjustment: 70mm-240mm Focus adjustment: focus number, focus position Image processing: pseudocolor, grayscale correction, image smoothing, histogram Frequency adjustment: 3 files Frame related adjustment: support Scanning angle: Visually adjustable Measure backfat: (+1mm) Continuous working time: more than 3 hours Dimensions length: (278mm) * width (165m) * height (38mm) Power consumption: 10W 1.5 Working principle According to the characteristics of different tissues and organs with different densities and different ultrasonic propagation speeds, that is, different acoustic impedances (the product of the medium density and the sound speed), the B-type ultrasonic diagnostic instrument uses a certain regular electric pulse to excite the piezoelectric chip ( transducer) to generate ultrasonic waves of a certain frequency, inject this ultrasonic wave (sound energy) into the body, and generate reflected echoes through the interface of different organs in the body; the reflected echoes of different sizes are transmitted by the original ultrasonic wave transducer connection The received echo (sound energy) is converted into electrical pulses, which are processed by amplification, detection and digital scan conversion to form a standard video signal, and the cross-sectional image of the organ is displayed on the monitor screen. .
