Parametric models for the arterial input function (AIF), both
literature-based (Tofts-Kermode and Fritz-Hansen) and data-adaptive.
Kinetic parameter estimation using a variety of compartmental models
(e.g., Kety, extended Kety, etc.)
Estimation via nonlinear regression (Levenburg-Marquardt optimization) or
Bayesian methods (MCMC)
Semi-parametric methods via Bayesian P-splines (MCMC)
A detailed vignette has been included as a "tutorial" for the package and
