Real time MR temperature imaging during thermal therapy is beneficial for monitoring and controlling the treatment in clinical applications. In this work, we explored correlations in the temporal dimension of temperature imaging and proposed a novel method, temporal weighted sliding window SPIRiT using motion-insensitive golden angle radial sampling, to achieve real time temperature imaging. Through simulation studies and phantom heating experiments, we validated the ability of the proposed method to obtain temperature images with relatively high temperature accuracy at a reduction factor of 8.
