Within this study, we propose a technique for MR
thermometry close to metal. The technique utilizes a
multispectral imaging approach and the temperature
dependency of the T1 relaxation time. Within a phantom
experiment, initial feasibility is demonstrated by
tracking the T1 change close to a metal implant during
heating.
