Step-by-step solution
In sonography (ultrasound imaging), inaudible high frequency of sound waves in the range of 1-5 MHz are used. Related Theory Sonography is a medical imaging technique that uses high-frequency sound waves to produce images of internal body structures. It is also known as ultrasound. After the X -ray test, ultrasound is the most used diagnostic imaging technique. It uses a device called a transducer to send out ultrasound waves and listen for the echo. A computer translates the ultrasound waves into an image. A train
