Automated Determination of Arterial Input Function for Dynamic Susceptibility Contrast MRI from Regions around Arteries Using Independent Component Analysis

Figure 1

(a) The physiological signals for artery (I), surrounding tissue (II), and tissue (III) are simulated in three blocks (in red, green, and blue, resp.). The partial volume fractions between (I, II) and (II, III) were 0.5. (b) The generated raw signals were calculated from Kiselev’s approach [30].
