DenseNeuroVol-class: DenseNeuroVol Class

In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

DenseNeuroVol Class

Description

Represents a three-dimensional brain image backed by a dense array. This class combines the spatial properties of NeuroVol with the data storage capabilities of an array.

Construct a DenseNeuroVol instance

Usage

DenseNeuroVol(data, space, label = "", indices = NULL)

Arguments

data	a three-dimensional array
space	an instance of class NeuroSpace
label	a character string
indices	an optional 1-d index vector

Details

DenseNeuroVol objects are used for 3D brain images where most or all voxels contain meaningful data. They provide efficient access to individual voxel values and are suitable for operations that require frequent random access to voxel data.

Value

DenseNeuroVol instance

Examples

# Create a simple 3D brain volume
vol_data <- array(rnorm(64*64*64), c(64, 64, 64))
vol_space <- NeuroSpace(dim=c(64L, 64L, 64L), origin=c(0, 0, 0), spacing=c(1, 1, 1))
brain_vol <- new("DenseNeuroVol", .Data=vol_data, space=vol_space)
