What is USG velocity and explain in detail?
Answer: d) Is lower in tissues with a higher fat or water contentUltrasound velocity:It is a product of the frequency and wavelengthIt is inversely proportional to the square root of the material densityUltrasound travels faster in stiff, non-compressible mediaVelocity in a given medium is virtually independent of the frequency. With velocity being constant, an increase in the frequency causes a proportional decrease in wavelengthThe velocity of ultrasound in fat and water is lower than in an average soft tissue.
