R Documentation

Reverse 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_uncorrect(t_start, t_end, tac, 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`	The uncorrected radioactivity values.
`radioisotope`	The radioisotope.

Value

The tac before decay correction

Examples

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

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