patlak.plot: Patlak plot implementation

In traceRkinetic: Kinetic analysis for dynamic nuclear imaging: compartmental models

Description

Implements a Patlak plot linear analysis, another graphical method for analysis of tracers that can be modeled after an irreversible two-tissue compartment model.

Usage

  patlak.plot(input.function, tissue, time.start, time.end,
    plot = TRUE, ...)

Arguments

input.function	Input function TAC.
tissue	Tissue TAC.
time.start	Initial acquisition time for each frame.
time.end	Final acquisition time for each frame.
plot	Should the Patlak plot be displayed? Defaults to TRUE.
...	Additional parameters passed to the plot function.

Details

Please refer to the documentation of processlinear for implementation details.

Value

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.
