1. An apparatus comprising:

  • a magnetic resonance imaging system, the magnetic imaging system comprising;

    a magnet,magnetic gradient field coils, anda radio frequency coil;

    a processor for controlling the apparatus; and

    a memory storing machine readable instructions for execution by the processor, wherein execution of the instructions causes the processor;

    to control the magnetic resonance imaging system to generate a spectroscopic pulse sequence and in response thereto to acquire spectroscopic magnetic resonance data for an imaging zone,to produce a calibration thermal map of the imaging zone from the acquired spectroscopic magnetic resonance data,to control the magnetic resonance imaging system to generate a magnetic resonance thermometry pulse sequence and in response thereto to acquire baseline magnetic resonance thermometry data for the imaging zone, andto repeatedly;

    control the magnetic resonance imaging system to generate the magnetic resonance thermometry pulse sequence and in response thereto to acquire additional magnetic resonance thermometry data for the imaging zone, and produce a temperature map of the imaging zone from the calibration thermal map, the baseline magnetic resonance thermometry data, and the additional magnetic resonance thermometry data.
