1. A method for magnetic resonance (MR) thermometry of a patient, comprising:
operating an MR data acquisition unit, in which the patient is situated, to acquire first MR data from the patient at a first point in time;
operating said MR data acquisition unit in which said patient is situated to acquire second MR data from the patient at a second point in time that occurs after said first point in time;
providing said first MR data and said second MR data to a computerized processor and, in said processor, automatically determining a temperature of a first region of the patient by determining a phase shift between said second MR data in said first region, as a measurement phase, and said first MR data in said first region, as a reference phase;
in said processor, automatically determining a temperature in a second region of the patient, which is different from said first region, by determining a phase shift between said second MR data in said second region, as a measurement phase, and said second MR data in a third region of the patient that is different from said first region, and that is situated adjacent to said second region, as a reference phase; and
making the temperature determined in at least one of said first region or said second region available at an output of said processor in electronic form.
