input.function |
Input function TAC. |
tissue |
Tissue TAC. |
time.start |
Initial acquisition time for each frame (in minutes). |
time.end |
Final acquisition time for each frame (in minutes). |
K1.start,k2.start,k3.start,vB.start |
Initial parameter values. |
K1.lower,k2.lower,k3.lower,vB.lower |
Parameter lower bounds. |
K1.upper,k2.upper,k3.upper,vB.upper |
Parameter upper bounds. |
left.ventricle |
Left ventricle TAC, used for
spill-over corretion. Defaults to
|
weight |
Weight vector for the non-linear squares fit. Defaults to frame length. |

Other parameters passed to the plot function, if used. |
Returns a list with three fields: kparms
, the
computed kinetic parameters; stderrors
, the
standard errors for each parameter as a percentage;
fit
, the actual fitted object.
