Figure 1From: Robustness to noise of arterial blood flow estimation methods in CT perfusionExample of TAC used for the study. An example of TAC used for this study (patient # 1, internal numbering). Dashed and dotted lines represent respectively aorta and portal TAC obtained from real perfusion images. Black stars mark a Cl(t) (tumour TAC) estimated with the simulation study.Back to article page
