Anatomical Phase Extraction (APE) Method: A Novel Method to Correct Detrimental Effects of Tissue-Inhomogeneity in Referenceless MR Thermometry—Preliminary Ex Vivo Investigation

Figure 6

(a) Temperature maps derived from the multibaseline (standard reference) method. (b) Temperature maps derived from the proposed APE (top row), RW- referenceless (middle row), and referenceless (bottom row) methods. (c) The difference between temperature maps of the multibaseline method and the other three methods. Background artifacts in the RW- referenceless and referenceless methods are strikingly obvious. The proposed APE method markedly reduced these background artifacts.
