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.
