Representative axial slices. The healthy participant group metrics (rCBF, rCBV and MTT) obtained using the three analyses with their associated whole brain histograms for gray matter, GM (red) and white matter, WM (green). The THx-dOHb-Step analysis also provides an R2 goodness of fit measure and a blood arrival time relative to the reference cursor time; negative values indicating arrival before the reference cursor time, positive after.
