At high frequencies attenuation does not permit enough acoustical power to be transmitted to the target whereas at low frequencies the transmitted power is not absorbed efficiently. Hence, there exists an optimum frequency at which the power deposited at the target is maximum. In this study, we verified this relation experimentally using MR compatible focused transducers, ex-vivo tissue samples and magnetic resonance (MR) thermometry. © 2014 IEEE.EnglishTissueTransducersUltrasonicsAcoustical powerFocused transducerFrequency optimizationHigh frequency HFHigh intensity focused ultrasoundMR-compatibleOptimum frequencyTransmitted powerMagnetic resonanceConference Paper10.1109/ULTSYM.2014.0101
