Description

This interpolation process (actually, an extrapolation) is needed to convert the given TAC into a signal with frames of equal length. This length is the minimum frame length for the given study.

Usage

  interpolate.tac(tac, time.start, time.end,
    interpolation.type = 1)

Arguments

tac

The TAC to be interpolated.

time.start

Initial acquisition time for each frame.

time.end

Final acquisition time for each frame.

interpolation.type

Interpolation type. 1 for linear, 2 for "natural" splines. Defaults to 1.

Value

A list containing tsample, the sampling time vector and the y, the interpolated TAC.
