decay_correct: Perform Decay Correction of TAC values

In mathesong/kinfitr: Kinetic Modelling of PET Time Activity Curves

Perform Decay Correction of TAC values

Description

This function uses the equation described here to perform the calculations: http://www.turkupetcentre.net/petanalysis/decay.html

Usage

decay_correct(t_start, t_end, tac_uncor, radioisotope = c("C11", "O15", "F18"))

Arguments

t_start	The starting times of the frames in minutes.
t_end	The end times of the frames in minutes.
tac_uncor	The uncorrected radioactivity values.
radioisotope	The radioisotope.

Value

The tac after decay correction

Examples

data(pbr28)
s1 <- pbr28$tacs[[1]]

# Assuming the data were not decay-corrected (they are)
decay_correct(
  s1$StartTime/60,
 (s1$StartTime + s1$Duration)/60,
 tac_uncor = s1$FC)
