A Specific Absorption Rate (SAR) Dosimeter for RF Power Deposition in MRI

Case ID:

C05181

Featured is a dosimeter device that measures SAR deposited by RF power deposition during MRI of a specimen. Such a dosimeter device includes a transducer that is configured to present a load to the MRI scanner in which the transducer is located and to provide an output representative of signals induced in the transducer. The transducer also is configured so that the presented load is substantially equivalent to another load which would be presented by the specimen during MRI of the specimen. Such a transducer also is configured so as to generate an MRI signal that is sufficient to allow the MRI scanner to adjust the RF power to a value substantially equal to that of the specimen. Also featured are methods for measuring SAR deposited by RF power deposition and apparatuses or system embodying such a dosimeter device.
