An 11-channel cylindrical ladder coil was built to increase SNR to improve temperature measurement, cancer verification, and tissue characterization for MR guided high intensity focused ultra-sound over a single chest coil. The HIFU coil was found to improve such aspects of temperature measurement by using SNR plots, g-factor maps, human anatomy images, and temperature maps. For future human studies, this coil can add to patient safety and treatment efficacy.
