Whether it is a health checkup or a visit to the hospital, the doctor always asks the patient for an ultrasound examination. Most people’s understanding of ultrasound machine is used for testing pregnant women . In fact, ultrasound machine is not just only used for pregnant women to examine the fetus. It is only a small part of the clinical application of ultrasound. But what exactly is ultrasound machine? How does it inspect the human body?
Ultrasound is acoustic energy in the form of waves having a frequency above the human hearing range. The frequency of sound waves that our human ears can hear is 20 to 20 000 Hz. When the vibration frequency of the sound wave is more than 20 000 Hz or less than 20 Hz, we cannot hear it. Therefore, we call sound waves with a frequency higher than 20 000 Hz as "ultrasound." Ultrasonic has the characteristics of good directionality, strong penetrating ability, easy to obtain relatively concentrated sound energy, and long transmission distance in water. It can be used for distance measurement, speed measurement, cleaning, welding, gravel, etc., Most widely used in medical science, military, industry, and agriculture.
The ultrasonic frequency usually used for medical diagnosis is 2-10MHz. It can be transmitted in the human body, and part of it can be reflected back after touching different tissues. Based on this physical characteristic, scientists have developed various ultrasonic instruments. Ultrasound is generated and emitted by the probe. After entering the human body, according to the differences in the acoustic properties of human organs and tissues, part of the ultrasound is reflected back, and then received by the probe and processed by the computer, displayed and traced in the form of waveforms, curves or images. The diagnostic method used by sonographers to distinguish physiological and pathological conditions based on image characteristics is ultrasonic examination.
Ultrasound machine is widely used in the human body diagnosis, covering the brain, heart, blood vessels, liver, gallbladder, pancreas, spleen, chest cavity, kidney, ureter, bladder, urethra, uterus, pelvic appendages, prostate, seminal vesicles, as well as eyes, thyroid, breast, Salivary glands, testes, peripheral nerves and tendons of limbs, etc. It is a very important machine in radiography and offer valuable pathological image for doctors to obverse the diseases. Ultrasound diagnosis has many advantages: no pain and no harm to the examinee, convenient examination, intuitive and clear images, so it is very popular among doctors and patients
