A system includes an acoustic radiation force source that is structured to generate an acoustic radiation force at one or more frequencies. A shear wave transmission device is embedded in a mass including a biologic material. The shear wave transmission device is responsive to the acoustic radiation force source to transmit shear waves through the biologic material. A Doppler ultrasonic device detects the shear waves and generates data representative of the shear waves. A processing device determines one or more mechanical properties of the biologic material from the data.
