The difference between veterinary B-ultrasound and human B-ultrasound:
1. The structure of humans and beasts have different reflection angles:
Because the body structure of animals is different from that of humans, the B-ultrasound has also changed the angle of irradiation, so that everyone can better illuminate the physical strength of animals. Therefore, all humans can be used for veterinary use, but for veterinary use It is generally not convenient to use on people.
2. Volume difference:
The B-ultrasound machines that people use are generally larger because they don’t need to be moved frequently, while the veterinary B-ultrasound is different, because many large animals cannot be transported, but the instrument needs to
3. The cost is different:
The B-ultrasound for human use may strive for perfection, only seeking the most advanced technology and the best effect, but for veterinary use, there is no need to meet too high requirements, as long as the basic functions of the B-ultrasound are met, it is more important. Cost is a problem, so veterinary products are basically very cheap in terms of cost.
The similarities between veterinary B-ultrasound and human B-ultrasound:
The veterinary B-ultrasound is a simplification of the human-use B-ultrasound. It is easy to operate while receiving the reflected waves from the internal organs of the animal and reflect the acquired image information on the screen. The basic components of the veterinary B-ultrasound include launch, scan, receive, The signal processing and screen display are divided into two parts: the host and the probe. The probe can be installed with one chip or multiple chips, the chips work in turn, can transmit and receive sound energy, and become a transducer. Probes are classified according to frequency, including single-frequency, multi-frequency, and broadband types.
The probe uses the ultrasonic waves from the host, and usually uses an anastomosis agent to coat the probe before touching the surface of the animal. The ultrasonic waves produce reflection, refraction, scattering, diffraction reduction, and the relative motion of the sound source and the receiver to produce Doppler at the interface of two different tissues. According to the physical characteristics such as monitoring the echo delay time, the strength can judge the distance and nature of the organ.
After processing by the electronic circuit and the computer, the physical characteristics are collected and displayed on the screen through the host computer. Become a different image. Our human ears can hear sound waves with a frequency of 20 Hz to 20 kHz. When the sound wave frequency is higher than 20 kHz, we humans cannot hear it. We call this sound wave with a frequency higher than 20 kHz as ultrasound. Ultrasound has good directivity and strong penetrating ability, and it is easy to obtain concentrated sound energy, especially for long-distance propagation in water. In human medicine, the use of the physical characteristics of ultrasound to analyze and diagnose diseases produces B-ultrasound. B-ultrasound is to transmit ultrasound to the human body while receiving the reflected waves from the internal organs of the human body, and reflect the acquired image information on the screen.
