Question

explain the technique of ultrasonography in short and brief .

Answer 1

Dear Student,

Ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. It is also used in micro welding. The weld is produced by the application of high frequency vibratory energy as the parts are held together with force. Bats use ultrasound waves to catch their prey by the process echolocation . In this process bats sends ultrasound waves from their mouth and if their is any prey in his way the ultrasound waves gets received by their ears and they can easily find their preys.
