We
introduce a new temperature estimation method that is a hybrid of
multi-baseline and referenceless methods. From multi-baseline methods the
hybrid method inherits the ability to estimate temperature in the presence of
rapidly-varying background anatomical phase. From referenceless methods the
hybrid method inherits robustness to smooth main field shifts during thermal
therapy. The method is demonstrated in the heart and liver.
