What is the purpose of ultrasonography? : Friends A method of obtaining images of body parts using ultrasound waves with frequencies greater than 30,000 Hertz (Hz). Inaudible sound (sound) waves sent from outside into the body are reflected as echoes to varying degrees by different tissues. These reflected sound waves can be converted into pictures with modern technology. This method used for diagnosis is called ultrasonography.
What is the purpose of ultrasonography?
Friends, now we will tell you What is the purpose of ultrasonography? Any vibrating object produces waves. Our ears can detect sound waves from 20Hz to 20,000 Hz; Therefore high frequency waves are called transonic or inaudible. A special crystal of lead zirconate titanate (lead zirconate titanate) with a smooth surface, placed in an electric field, moves back and forth in a suitable liquid, creating resonant waves. When these waves are focused with a transducer or probe on the part of the body where the two tissues meet, the various tissues in its path absorb, channel, or transmit the waves according to their properties. The time (speed) for the reflected wave to return is proportional to the distance the tissue is from the implant.
Thus absorption, reflection and momentum change the returning waves. The returning waves (the echoes) are picked up by the detector and immediately displayed as a picture on a fluorescent screen. In times of war, the Navy uses such transonic waves to locate submarines on the ocean floor, and bats use them to find their way.
Ultrasonography Benefits – What is the purpose of ultrasonography?
Friends, above we told you what is the purpose of ultrasonography? There are many advantages of ultrasonography. This method does not cause any injury and the repetitive technique for diagnosis is completely safe. Since ionizing radiation such as X-rays is not used, it is safe to use in children and women who are pregnant or giving birth. Plus, it’s acceptable to everyone, including kids, because it doesn’t require any kind of preparation.
These waves cannot pass through bones and air. Therefore, a satisfactory study of the brain, bones and gastrointestinal tract is not possible with ultrasound.
The main diagnostic uses of ultrasonography are as follows:
- Knowledge of the position of the fetus in pregnancy.
- study of the soft organs of the abdomen and pelvis; For example, liver, gall bladder, pancreas, spleen, kidney, bladder, prostate glands, uterus, ovaries, salivary glands and other soft tissue hyperplasia, tumours, inflammatory swelling and calculi can be diagnosed.
- Large blood vessels and malformations (malformations) of the heart and the speed, direction and amount of blood flowing through them can be studied by special methods such as echocardiography and Doppler ultrasonography, respectively.
- With the help of ultra-repetitive endoscopes, it has become possible to study organs in the upper layer of the body – the eye, thyroid and parathyroid glands.
- Many medical procedures have been made possible with the help of ultrasound. In this method biopsy is done and its exact location can be ascertained by aspiration of liquid pus or blood filled in any part of the body.
Various types of transsonic waves have been used to generate heat to move the bowels and quantify their vibrations to break up and dislodge stones from the urinary tract.
