if ultrasound can be used to measure elasticity

[muffinman123]

can you simply extract the elasticity from ultrasound medical images? I don't know ultrasound very much but I just found out it can measure elasticity.

under what condition can ultrasound be used to measure elasticity of some deformable object and do ultrasound medical images qualified for those conditions?

If you know the sound speed you will "calculate" de Young module. You need the sound speed (for you frecuency) for draw a medical image.
