Detection of RF power deposition is important in MRI SAR
analysis, and in RF safety of implanted leads. We
demonstrate thermo-acoustic ultrasound as a non-invasive
means to detect rapid RF power deposition at MRI
frequencies. Results are shown using CW modulation
methods for a exposed lead and stripline RF coil.
