Geometric Shape

Node Icon

Create an ellipsoid or cuboid shaped mask at a specified position in the reference image.

Inputs

Reference

Supply a reference image or mask. The output will have the same position, orientation, voxel size and shape as the reference.

Type: Image, Mask, Required, Single

Outputs

Output

Output mask

Type: Mask

Settings

Shape

Shape Selection

The geometric shape of the mask.

Values: Cuboid, Ellipsoid

Size [mm] 3D Vector

The size of the cuboid in the [i, j, k] dimensions, in units of mm.

Size [px] 3D Vector

The size of the cuboid in the [i, j, k] dimensions, in units of voxels.

Radii [mm] 3D Vector

The radii of the ellipsoid in the [i, j, k] dimensions, in units of mm.

Radii [px] 3D Vector

The radii of the ellipsoid in the [i, j, k] dimensions, in units of voxels.

Define Extent in Selection

Select the spatial unit as mm or voxels.

Values: mm, Voxels

Position

Center Definition Selection

Select how to define the center of the mask.

Values: Center Offset, Center Position, Center Index

Center Offset [px] 3D Vector

Define the center of the geometric shape as an offset from the center of the mask, in pixel units.

Center Offset [mm] 3D Vector

Define the center of the geometric shape as an offset from the center of the mask, in millimeters.

Define Offset in Selection

Select the offset unit as mm or voxels.
