Propagation of Blood Function Errors to the Estimates of Kinetic Parameters with Dynamic PET

Figure 6

Comparison between the estimated 𝑘₁, 𝑘₂, 𝑘₃, and 𝑘₄ of liver using the derived expressions and numerical approximation for a range of erroneous blood functions. Top two figures show results when all samples of the blood are erroneous, (a,b)/(c,d) when the initial peak is erroneous, and (e,f) when the tail part is erroneous.
