Beginner Tutorial Data Objects 2D Contours CSO 3D

Contour Example 3: Overlay Creation and 3D Visualization of Contours

This example is also available on YouTube.

Introduction

In this example, we’d like to use the created CSOs to display an overlay. This allows us to mark one of two lungs. In addition to that, we will display the whole segmented lobe of the lung in a 3D viewer.

Steps to Do

Develop Your Network

Use the network from the contour example 2 and add the modules VoxelizeCSO, SoView2DOverlay and View2D to your workspace. Connect the module as shown. The module VoxelizeCSO allows to convert CSOs into a voxel image.

Convert CSOs into a Voxel Image

Update the module VoxelizeCSOs to create voxel masks based on your CSOs. The result can be seen in View2D1.

Next, we like to inspect the marked lobe of the lung. This means we like to inspect the object that is built out of CSOs. In order to do that, add the View3D module. The 3D version of the lung can be seen in the viewer.
