Automatically generate an arterial input function mask.

Automated approach for generating a mask to be used for modeling the arterial input function using the method described in https://www.ncbi.nlm.nih.gov/pubmed/15956519.

generateAifMaskImage(perfusionImage, voiMaskImage, index = NA)

Arguments

perfusionImage

time series (n-D + time) perfusion acquisition.

voiMaskImage

n-D mask image indicating where the cerebral blood flow parameter images are calculated.

index

If the user prefers a specific voxel if looking at the plots, they can simply specify the index (gleaned from the file names) and the corresponding AIF mask image is created.

Value

list( mask image, fitting results )
