Several in vivo experiments are conducted to explain the applicability of the acoustic radiation force impulse (ARFI) imaging technique in various lower-limb vascular applications. The ARFI technique is shown to present clear images of the disease and hence is shown to be much more efficient than the traditional ultrasound methods.

A novel method of motion compensation for use with radiation force elastography is discussed. Results suggest the effectiveness of the proposed method for in vivo abdominal imaging.

The feasibility of acoustic radiation force impulse (ARFI) imaging with an intracardiac probe and its possible application for monitoring cardiac ablations are investigated. It is found that the intracardiac probe can define the boundaries of a stiffer spherical lesion clearly and hence can guide and monitor radiofrequency ablations within the heart.

Acoustic radiation force impulse (AFRI) imaging techniques were used to monitor radiofrequency (RF) ablation of ovine cardiac tissue in vivo. AFRI imaging, which requires no additional equipment, might be convenient modality for monitoring lesion formation in vivo.
