Sonogram vs. Ultrasound

Sonogram
Ultrasound

A sonogram is the image generated during ultrasonography, which is a diagnostic imaging technique that uses ultrasound to visualize anything inside the body. Ultrasound is sound with a frequency above the range audible to humans, about 20 kHz. In common parlance, both words are used to refer to the ultrasonography procedure.

Definition The image produced by ultrasonography High frequency sound. Used in ultrasonography to produce an image.
Uses Helps physicians observe growth of a fetus, calculate age and due date and see presence of multiple fetuses. Also used to diagnose pelvic bleeding or locate cancerous cells. Used to produce sonograms. Can also be used to ensure uniformity of liquids and to determine the depth of water.

edit What is Ultrasound and Sonogram?

Ultrasound is high frequency sound, inaudible to humans (approx. 20kHz).

Rough diagram of sound frequency scale, showing ultrasound and some applications.

When ultrasound waves are sent into the human body some of them bounce back when they hit tissues of differing density. The time it takes the reflected ultrasound waves to return to the machine is translated into an image of the internal organ, or of the fetus. This image is called an sonogram.

A sonogram is used by physicians to observe the growth of a fetus, to calculate their age and due date, and to see the presence of multiple fetuses. It is also used to diagnose internal problems such as pelvic bleeding, and to locate cancerous cells.

Ultrasound is used to produce a sonogram. It is also used in industry to measure the purity or uniformity of liquid, to measure the depth of water, and to search for underwater objects such as submarines. Whales and dolphins use ultrasound to communicate.

edit Uses of Ultrasound in Animal Kingdom

Basically humans are site centric species i.e. we experience world mainly through the sense of sight. However some animals use ultrasound or sonar waves to sense their environment.
