DenseNeuroVol Class

Source: R/all_class.R, R/neurovol.R
DenseNeuroVol-class.Rd

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

Value

DenseNeuroVol instance

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.

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)
