Magnetic resonance imaging (MRI)-based temperature mapping very close to the
surface of an ultrasound transducer is not possible due to the large magnetic
susceptibility- induced image artifacts that arise from the materials used in
transducer construction. Here, it is shown in phantoms that
"susceptibility-compensated" MRI sequences can be used to measure thermal
increases approximately 1 mm from the surface of a 4-element cymbal array
transducer, which has been used widely for noninvasive transdermal drug
delivery. The estimated temperatures agree well with those measured using
