Explanation: 

Detailed explanation-1: -How ultrasound scans work. A small device called an ultrasound probe is used, which gives off high-frequency sound waves.

Detailed explanation-2: -An ultrasound machine makes images so that organs inside the body can be examined. The machine sends out high-frequency sound waves, which reflect off body structures. A computer receives the waves and uses them to create a picture. Unlike with an x-ray or CT scan, this test does not use ionizing radiation.

Detailed explanation-3: -Transducers are the instruments that emit and receive ultrasound waves by way of electrical signal conversion to sound waves.

Detailed explanation-4: -The technology used is called “X-ray computed tomography” (CT), sometimes referred to as “computerized axial tomography” (CAT). A number of different types of X-ray CT systems are being promoted for various types of screening.
