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

Plot: Simplified Reference Tissue Model with Blood Volumes

Description

Function to visualise the fit of the SRTM_V model to data.

Usage

plot_srtm_vfit(srtmvout, roiname = NULL, refname = NULL)

Arguments

srtmvout	The output object of the SRTM fitting procedure.
roiname	Optional. The name of the Target Region to see it on the plot.
refname	Optional. The name of the Reference Region to see it on the plot.

Value

A ggplot2 object of the plot.

Examples

# Note: Reference region models, and irreversible binding models, should not
# be used for PBR28 - this is just to demonstrate function

data(pbr28)

t_tac <- pbr28$tacs[[2]]$Times / 60
reftac <- pbr28$tacs[[2]]$CBL
roitac <- pbr28$tacs[[2]]$STR
weights <- pbr28$tacs[[2]]$Weights

input <- pbr28$input[[2]]

newvals <- shift_timings(
  t_tac,
  roitac,
  input,
  inpshift = 0
)

bloodtac <- pracma::interp1(newvals$input$Time, newvals$input$Blood, t_tac)

fit <- srtm_v(t_tac, reftac, roitac, bloodtac, weights)

plot_srtm_vfit(fit)
