1540 m/s in soft tissue. 

331 m/s in air. 

While the true speed of a sound wave in soft tissue will vary depending on the density and elasticity of the tissue it is passing through, for the purposes of ultrasound physics, the speed is assumed to be the same as the speed through water. 

This assumption of the speed of sound can cause artifacts in ultrasound images, which can sometimes be helpful in making an ultrasound diagnosis.

Nurali, I'm afraid your assumption is wrong. The speed of sound in water is slower than in soft tissue. The speed of sound in a medium is inversely related to the bulk modulus, or stiffness/elasticity, of the medium. the stiffer the medium, the faster.
