A 3D multi-contrast MRI pulse sequence is presented here
as a novel method for performing Acoustic Radiation
Force Imaging simultaneously with Proton Resonance
Frequency thermometry. This could be used, for example,
to safely localize the ultrasound focal in three
dimensions before an MR guided Focused Ultrasound
treatment while simultaneously measuring the induced
temperature rise.
