KAT.plot: Plots multiple image slices.

In KATforDCEMRI: Kinetic Analysis and Visualization of DCE-MRI Data

Description

Plots multiple image slices on the same color scale within a single PDF file.

Usage

KAT.plot(F1=0, F2=0, F3=0, F4=0, F5=0, F6=0, F7=0,
F8=0, plot.param="Ktrans", range.map = 1.5, cutoff.map=0.85, ...)

Arguments

F1	KAT output file containing parametric map 1.
F2	KAT output file containing parametric map 2.
F3	KAT output file containing parametric map 3.
F4	KAT output file containing parametric map 4.
F5	KAT output file containing parametric map 5.
F6	KAT output file containing parametric map 6.
F7	KAT output file containing parametric map 7.
F8	KAT output file containing parametric map 8.
plot.param	Which parameter will be plotted? Can be set to Ktrans, kep, vb or ve. (Default=Ktrans).
...	Arguments passed on to inner functions.
range.map	Specifies range of color scale relative to the max value within map (typically a value between 1 and 3; default=1.5).
cutoff.map	Truncate parametric map values by max value x cutoff (typically a value between 0 and 1; default=0.85).

Details

For n slices, 3 x n figure panels will be generated where n is the number of slices to be plotted. MAP is the parametric map for the slice of interest, while AIC is the model discrimination map for the slice of interest. ROI is the median contrast agent concentration-time profile over all voxels within the region of interest shown with associated estimated extended Tofts model parameters.

Examples

## Create temporary directory for example code output files
temp_dir <- tempdir(check=FALSE)
##
current_dir <- getwd()
setwd(temp_dir)
##
## Run example code
demo(KAT, ask=FALSE)
file1="KAT_benchmark_test-full_slice1.RData"
file2="KAT_benchmark_test-full_slice2.RData"
file3="KAT_benchmark_test-full_slice3.RData"
file4="KAT_benchmark_test-full_slice4.RData"
KAT.plot(F1=file1, F2=file2, F3=file3, F4=file4, export.matlab=FALSE)
##
setwd(current_dir)
