We validate the feasibility of simultaneous multi-slice EPI to monitor the volumetric temperature of the target tissue with high temperature accuracy during MRgFUS treatment. The average uncertainty of the measured temperature is less than 0.4C for an ex-vivo porcine tissue. This approach allows researchers to monitor the temperature of the whole brain, especially the brain surface and scalp. It can be used to prevent undesired heating during MRgFUS treatment of the brain.
