it is because ultrasound help us to hear sound.it helps to see the muscles tendons and many organs to capture size and structure

What is the purpose of sonograms?
In a sonogram, ultrasound waves are sent to the part of your body being examined, and these waves are displayed as images. These images help doctors to determine if there are any abnormalities in the area of the body being examined. Sonograms are also used to allow pregnant women and their doctors to see a baby before it is born.
What are ultrasound?
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
Sonograms Versus X-Rays?
Unlike x-rays, sonograms are completely harmless and do not involve radiation. They simply involve high-frequency sound waves that allow an ultrasound technician to see organs, muscles, tendons, and tissues. An ultrasound's only effect is warming of the tissues at which it is directed. The process is so safe that one of its main uses is on pregnant mothers and fetuses. The procedure is also non-invasive and painless. Uncertainties about this technology are of the past.
Why are sonograms made with ultrasound waves instead of audible waves?
The higher the frequency the shorter the wavelength, so by the physics of sound waves, the smaller the objects that can reflect the sound back. Hence using ultrasound, with its very short wavelengths, the better the definition attainable.
What is Endorectal ultrasound?
Endorectal ultrasound (ERUS) is a procedure where a probe is inserted into the rectum and high frequency sound waves (ultrasound waves) are generated
How are ultrasound waves produced?
this is not how they are made naturally but how they are made for diagnostic uses: ultrasound waves are made by applying a current that is similar to the natural frequency of the piezoelectric quartz crystal, when this is applied to the crystal they produce ultrasonic waves! ADDED: As a point of detail, quartz is rarely if ever used now, replaced by much more sensitive, artificial, piezoelectric ceramics.
Are there any uses of ultrasound in medicine?
yes when you get an ULTRASOUND when your pregnant it use ultrasound waves to show the image.
What is ultrasound waves?
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
How are sonograms produced?
Sonograms are used to look at things inside the body including organs, blood vessels, bones, and fetuses. They are basically sound waves that are reflected off of different tissues. They are then received and displayed on a monitor. It works in much the same way RADAR is used to detect aircraft that are in the air, except they use sound waves instead of radio waves.
Which use of sound waves depends on the fact that sound waves are reflected?
ultrasound
What jobs use ultrasound waves?
Doctors use ultrasound to check the health of an unborn baby.
What is the functionality of ultrasound?
Ultrasound is typically performed by a trained ultrasound technologist, it involves using sound waves to get an image of the reproductive system.
