There are a few steps to performing an Ultrasound Scan.
1. The sonographer holds a transducer in his hand. The transducer is placed on the area where the image is to be taken—this helps to get a clearer picture.
2. Ultrasound travels through soft tissue. It bounces back, and the image is formed. (Ultrasound is the sound that the human ear cannot hear).
3. The ultrasound scan transmits high-frequency sound pulses using the transducer. For diagnostic purposes, the frequency ranges between 2 and 18 megahertz. The higher the frequencies better is the image quality. The images formed lower the frequencies of the waves are of lower resolution.
4. The sound waves travel through the organs and hit a boundary between tissues.
5. The sound waves get reflected, and the reflected waves are relayed back to the machine.
6. The monitor displays the echoes' distances and intensities, forming a two-dimensional image.
Why Do Doctors Ask For An Ultrasound?
Doctors recommend an Ultrasound test for diagnosis, treatment, and guidance during medical procedures. It examines internal organs like the liver, kidneys, pancreas, thyroid gland, and ovaries.
An ultrasound scan can show if there is an abnormal growth or tumor. It can help to identify problems with muscles, tendons, and joints. A person suffering from a frozen shoulder or tennis elbow can have an ultrasound test.
