Schematic representation of the centres of the FMs as localised by all the observers for patient P1 (top) and P9 (bottom) using multiple sequences (bSSFP, SPGR and GRE). The labelling of the FM is indicated by the marker: , x, + and ∙ for FM having number 1, 2, 3 and for agreement position, respectively. For patient P1 (top), the LoA CM of FM1 over the five RTTs was 0.27, 0.31 and 0.38 mm in X, Y and Z, respectively, which was considered clinically acceptable; for patient P9 (bottom), the LoA CM for FM2 over the five observers was 11.17, 0.99 and 13.70 mm in X, Y and Z, respectively, which was considered clinically unacceptable
