rCBV: Regional Cerebral Blood Volume

Description

...

Usage

rCBV(Ct, Ca, time, Hf=1, rho=1)
## S3 method for class 'array':
rCBV.fast(signal, mask, aif, time, multicore=FALSE, verbose=FALSE)

Arguments

Ct

...

Ca

...

time

is the vector of acquisition times associated with the dynamic data.

Hf

...

rho

...

signal

is a multidimensional array of signal intensities (or concentrations). The last dimension is assumed to be a function of the acquisition times, while the previous dimenions are assued to be spatial.

mask

is a (logical) multidimensional array that identifies the voxels to be analyzed.

aif

Arterial Input Function.

multicore

is a logical variable (default = FALSE) that allows parallel processing via multicore.

verbose

is a logical variable (default = FALSE) that allows text-based feedback during execution of the function.

Value

• A nifti object containing the estimates of regional cerebral blood volume (rCBV).
