1. A multibaseline method of performing proton resonance frequency (PRF) thermometry, the method comprising the steps of:

  • acquiring a plurality of PRF baseline images of an imaging region, each baseline image corresponding to a PRF phase background during the imaging region'"'"'s cycle of motion;

    acquiring a PRF treatment image of the imaging region subsequent to temperature change of a subregion within the imaging region;

    estimating a phase background of the imaging region by fitting a combination of the PRF baseline images to the treatment image; and

    estimating a temperature distribution within the subregion based on the treatment image and the estimated phase background.
