Acoustic radiation force impulse imaging: Remote palpation of the mechanical properties of tissue
An overview is given of the Acoustic Radiation Force Impulse (ARFI) imaging. It discusses the derivation of radiation force, the response of tissue to radiation force, and the potential for this imaging method to evaluate the mechanical properties of tissue. It is found that In vivo ARFI images of breast, abdomen, and carotid vessels demonstrate no speckle, good contrast between tissue structures, and resolution comparable to B-mode images.
