MR-ARFI is a novel method for monitoring HIFU treatments. We have previously shown how to improve the accuracy and precision of MR-ARFI by using the repeated bipolar gradients to encode the displacement. In this work, two practical aspects in the in vivo application of MR-ARFI are analyzed. The bulk motion sensitivity is considered, and a list of optimized encoding width for different tissue types is provided.
