In this research, we proposed an acceleration method for
model-based PRF temperature mapping using Echo-based
GRAPPA. The method can accelerate the MR temperature
monitoring at a net reduction factor of 2.3. The
temperature uncertainty and temperature RMSE is less
than 1.4C based on the ex-vivo goose liver experiment.
This technique is also insensitive to inter-frame motion
compared with other MR temperature measurement methods.
When combined with other traditional methods, the
combined method can measure the temperature of tissue
with multiple composition.
