When someone hears the word "ultrasound" they may quickly think about those ambiguous black and white computer screens showing images of babies, pregnancy, and fetal development. Modern medicine goes far beyond the granular planar image that the mother often sees. Not only in medical institutions, but also in veterinary clinics, even three- or four-dimensional imaging is possible. In the 1970s and 1980s, only a few universities used this technology, but today the progress and availability of modernization made it possible to rely on this technology to cope with the situation.
Medical ultrasound (also known as diagnostic ultrasound or ultrasound) is imaging diagnostic technology based on ultrasound application. It is used to look at internal structures of tendons, muscles, joints, blood vessels, internal organs. Its purpose is usually to locate the cause of the disease or to eliminate any medical condition. Using ultrasound to examine pregnant women is called obstetric ultrasound and is widely used. Ultrasound is a sound wave whose frequency is higher than the human audible frequency (> 20,000 Hz). An ultrasound image, also known as an ultrasound image, is created by sending an ultrasound pulse to the tissue using a probe. The sound echoes from the tissue, and different levels of sound are reflected to different tissues. We record these echoes and display them as images on the operator
Doppler ultrasound is a special use of ultrasound to measure the direction and velocity of blood cells moving in blood vessels. The movement of the blood cell causes a change in the pitch of the reflected sound waves (called the Doppler effect). The computer collects and processes sounds and creates graphics or color images that represent the blood flowing through the blood vessels. After entering the checkpoint, a radiologist (physician responsible for supervision and interpretation of the radiological examination) or ultrasonic examination technician will use the thermogels in the body area under examination. The gel keeps the transducer in safe contact with the body, eliminates the air pocket between the transducer and the skin, and prevents sound waves from entering the body. Place the transducer on the body and move it back and forth over the area of interest until the desired image is taken
