Quantitative MRI measurements near metal objects

A method for providing a thermal therapy treatment using an MRI system and a thermal therapy device in a region sufficiently close to a metal object, so that the metal object induces artifacts, comprising:

• heating the region using the thermal therapy device;
• acquiring through the MRI system at least one MRI signal from the region, wherein the acquiring uses a multispectral imaging and wherein the acquiring uses a spatially selective inversion pulse matched to excitation;
• processing the acquired at least one MRI signal to correct for artifacts induced by the metal object;
• extracting temperature from the processed at least one MRI signal;
• and
• changing the heating of the region based on the extracted temperature.

A system for providing thermal therapy treatment to a region sufficiently close to a metal object, so that the metal object induces artifacts, comprising:

• a thermal therapy device for providing heat to the region;
• a MRI system;
• and
• a controller comprising:
• a central processing unit;
• and
• tangible computer readable media, comprising:
