Module Description

Masks two images. The output image is set to 0 everywhere except where the chosen label from the mask volume is present, at which point it will retain it's original values. Although all image types are supported on input, only signed types are produced. The two images do not have to have the same dimensions.

Use Cases

Most frequently used for these scenarios:

• Use Case 1: Extracting the region or structures of interest using the mask.

Examples of the module in use:

• Recovering the bone structures using a mask on CT images
