It shows data from a subject with brain tumor having B_1rel value 1.15 in the tumor region pointed by the arrow. a The post contrast T₁W image. b The relative B₁ map (B_1rel) of the corresponding slice. c The concentration curve over 32 time points at the tumor location denoted by the arrow in (a) before and after B₁ inhomogeneity correction. d The relative error in concentration over the time points. The first 7 time points are excluded as contrast reaches tissue at ~ 8th time point. e The percentage error in perfusion parameters before and after B₁ correction
