Abstract
During the thermal treatment of an anatomical zone of interest, tissue temperature within the zone may be determined with a computational model whose parameters are adjusted using spectroscopy-based temperature measurements at interfaces of fat and non-fat tissues.
Claims27
A method of performing spectroscopy-based magnetic resonance (MR) temperature measurement, the method comprising the steps of:
- acquiring spectroscopy-based temperature measurements in defined regions along an interface of an anatomic zone of interest;
- using a prediction model, computationally predicting the temperature in the defined interface regions;
- adjusting the prediction model based on the temperature measurements;
- and
- computationally generating a temperature map of the zone of interest using the adjusted prediction model.

A system for performing spectroscopy-based magnetic resonance (MR) temperature measurement, the system comprising:
- (a) an MRI unit for acquiring spectroscopy-based temperature measurements in defined regions along an interface of an anatomic zone of interest;
- (b) a storage unit for storing a prediction model and parameters associated therewith;
- (c) a computer, in communication with the MRI unit, configured to:
- predict, using the prediction model, the temperature in the defined interface regions;
- adjust the stored parameters of the prediction model based on the temperature measurements;
- and
- generate, using the prediction model and the adjusted parameters, a temperature map of the zone of interest.
