GetSliceFromVolume3d

Extracts a slice orthogonal to an axis of a 3D volume.

Access to parameter description

The GetSliceFromVolume3d algorithm extracts a slice from a plane of a 3D image. This plane can be orthogonal to the X, Y, or Z axis.
The 2D image is created with dimensions deduced from the volume dimensions and the selected axis:

$\begin{array}{|c||c|c|c||} \hline \textbf{Selected Axis} & \textbf{Plane} & \textbf{$gx_s$} & \textbf{$gy_s$} \\ \hline \hline \textbf{X} & YZ &gy_v & gz_v \\ \hline \textbf{Y} & XZ & gx_v & gz_v \\ \hline \textbf{Z} & XY & gx_v & gy_v \\ \hline \end{array}$ Where

$(gx_v, gy_v, gz_v)$ is the input volume size in voxels for the X, Y, and Z directions and

$(gx_s, gy_s)$ is the output slice size in pixels for the X and Y directions.
