ARFI imaging and focal spot positioning procedure. Step 1: an anatomy image and an ARFI image are acquired and reconstructed in real time. Step 2: the target is chosen on the anatomy image (a, blue arrow), while the current position of the focal spot is determined using the ARFI phase image (b). Step 3: a feedback on the motors allows reaching the previously defined target location (b, red arrow). Step 4: the phase of an ARFI image acquired after the transducer displacement allows verifying that the desired target location has been reached (c, blue arrow)
