Patlak plot implementation

Share:

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

1
2
  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.
