Animal B-ultrasound generates ultrasound waves of a certain frequency based on the different densities and ultrasound propagation speeds of different tissues and organs in animals, that is, the characteristics of different acoustic impedances. This ultrasound wave is then injected into the animal's body and reflected back waves are generated through the interfaces of different organs in the body; The reflected echoes of different sizes are processed by the received echoes, detection, and digital scanning to form standard video signals, which are displayed on the monitor screen as cross-sectional images of organs. A high-tech method for cross-sectional observation of living organisms without any damage or stimulation has become a beneficial assistant for veterinary diagnostic activities and an essential monitoring instrument for scientific research such as live egg collection and embryo transfer.

Real time Veterinary Ultrasound imaging: Veterinary Ultrasound Equipment has a very short scanning or imaging time (strictly speaking, it should be completely synchronized with animal body movement), and can fully track changes in animal tissue, such as holographic projection images of veterinary ultrasound, projection images of sound tubes, and transmission type ultrasound microscopy images.

Quasi real time veterinary ultrasound: The scanning and visualization time is short, generally above 8 images per second, and can basically track changes in animal tissue. At present, various widely used types such as animal B-ultrasound, animal A-scan, animal backfat analyzer, animal color ultrasound, animal M-ultrasound, and animal blood color imaging belong to this category.

Non real time veterinary ultrasound: The scanning and visualization time is relatively long, and generally less than 1 image per second is considered non real time. This type of diagnostic technology, although unable to track changes in animal tissue, such as veterinary ultrasound holography, veterinary ultrasound CT, veterinary cervical Doppler equipment scanning images, veterinary handheld scanning imaging, etc., has significantly improved image quality due to high scanning density or line count.
