Abstract
Systems and methods for performing magnetic resonance (MR) thermometry include a magnetic resonance imaging (MRI) unit and a controller in communication with the MRI unit and configured to cause the MRI unit to acquire one or more baseline phase images of an imaging region and one or more treatment phase images of the imaging region subsequent to a temperature change of a subregion within the imaging region, electronically generate a thermal map pixelwise indicating the temperature change of the subregion based at least in part on the acquired baseline phase image and treatment phase image, computationally predict the temperature change of the subregion based at least in part on energy deposited in the subregion during treatment without reference to the generated thermal map, and determine whether the thermal map is inaccurate based at least in part on the temperature change of the subregion indicated by the thermal map and the predicted temperature change of the subregion.
