Role of vet ultrasound in animal pregnancy examination
Detailed function description of the veterinary ultrasound machine for animal pregnancy examination: 1. Check whether the animal is conceived successfully 2. Observe embryonic development: Judge the embryonic development by observing the changes of the fetus’s external structure and internal structure. 3. Monitoring the life and death of the fetus: Using ultrasound to detect the heartbeat of the fetus can predict the life and death of the fetus. Before the embryo dies, the heartbeat is significantly reduced. Fetal movement disappears, the fetal sac is filled with dark areas of liquid, the embryo cannot be seen, the echo in the uterus is disordered, and the fetal sac, placenta, and fetal structure cannot be distinguished, all indicating embryonic death. 4. Fetal heart rate and its pulsation: Fetal heart rate can be calculated by measuring fetal heart or fetal arterial pulsation (including umbilical cord artery-referred to as fetal blood sound). 5. Identify the sex of the fetus: Using ultrasound to detect the positional relationship between the reproductive structure of the fetus and the surrounding structures can accurately identify the sex of the fetus. 50 to 105 days after the cattle are bred, the accuracy of identifying the sex of the fetus is 96%. 6....

The Working Principle Of RVG Sensor
X-rays were invented 122 years ago by WH Roentgen. These have found various applications, such as in manufacturing, medical imaging and other fields. X-rays also play a vital role in the dental field. The dentist takes radiographs to understand the damage to the tissue under the gem. With the advancement of technology, dental imaging technology has also made great progress. Digital radiography was introduced into the dental field by French dentist DR. Francis Moyen, 1987. Seeing the effectiveness of this technology, various changes have been made, and new systems are being developed to implement this technology. Digital radiography is also called RadioVisioGraphy. The RVG sensor is used for digital radiography. The working principle of RVG sensor The sensor has two sides: reactive power and reactive power. The reaction side should be used to capture images. The tissue is exposed to X-ray radiation, and the refracted light is captured by the sensor. Process the image immediately and convert it to digital data using an analog-to-digital converter. These digital data are sent to the computer, where the doctor can immediately view the scan results. The cable attachment is located at the invalid end of the sensor. When the non-reactive surface is exposed...

Ultrasonic examination method of B-ultrasound machine for large animals
Ultrasonography of animals is the second most commonly used imaging format in veterinary practice. It uses ultrasound waves in the 1.5-15 megahertz (MHz) frequency range to create images of animal structures based on echo patterns reflected from the tissues and organs to be imaged. Several types of image formats can be displayed. B-mode grayscale scanning is one that creates images of actual anatomy. The sound beam is generated by a transducer that is in contact with the transmission gel and coupled to the animal through acoustic transmission. Ultrashort pulses of sound are introduced into the animal, and the transducer switches to receive mode. Echoes occur as the beam velocity changes when the beam is shifted from one density of tissue to another, even though this change occurs on an almost microscopic level. The greater the speed change, the greater the echo intensity. A small portion of these echoes is reflected back to the transducer, which then converts the echo’s energy into electrical impulses that are recorded by a computer in the ultrasound machine. The strength of the echo, the time it takes for the echo after the pulse, and the direction of the sound beam sent are all recorded. The...
