Purpose

The module GetVoxelValue gets the value of an input image to a corresponding world or voxel coordinate.

The value is written into a field, so it can be used in a network.

Visible Fields

Position

name: position, type: Vector6, default: 0 0 0 0 0 0, deprecated name: worldCoordinateInput

Sets the position that is interpreted according to Input Coordinate System.

Stored Value

name: storedValue, type: Double, persistent: no, deprecated name: voxelDoubleValue

Shows the actual image value at the given position.

Stored String Value

name: storedStringValue, type: String, persistent: no, deprecated name: voxelStringValue

Shows the actual image value at the given position as a string.

Voxel value is valid

name: valid, type: Bool, persistent: no, deprecated name: voxelValueValid

Shows whether the output fields are valid.

Update Mode

name: updateMode, type: Enum, default: AutoClear

Defines the update mode of this module.

Values:

Title	Name	Deprecated Name	Description
​Clear	​AutoClear	​Off	​Nothing happens if the input or any field changes.
​Update	​AutoUpdate		​The output fields are computed anew on any field or input image change.

Output Value

name: outputValue, type: Double, persistent: no

Shows the medical image value at the given position. This means that the DICOM Rescale/Slope of the input image are applied to the image value.

Output String Value

name: outputStringValue, type: String, persistent: no

Shows the medical image value at the given position as a string. This means that the DICOM Rescale/Slope of the input image are applied to the image value.

Input Coordinate System

name: coordinateType, type: Enum, default: World

Defines the coordinate system the Position is interpreted in.

Values:

Title	Name
​World	​World
​Voxel	​Voxel

Update

name: update, type: Trigger, deprecated name: updateButton

When pressed, the module computes anew.

Interpolation

name: interpolation, type: Enum, default: NearestNeighbor

Defines the used interpolation.

Values:

Title	Name	Description
​Nearest Neighbor	​NearestNeighbor	​Selects the nearest voxel value and does not interpolate.
​Trilinear	​Trilinear	​Calculates the result value using trilinear interpolation on eight neighboring voxels. At the borders, it clamps to the edges of the image. NOTE: Trilinear interpolation is currently supported only for scalar types. For non-scalar types, the module always uses nearest neighbor sampling.
