SpineSegmentation module for Slicer 3.6

Load volume into Slicer3.6 and select the SpineSegmentation module

Select input and output nodes and click Apply

Processing takes approx. 3 minutes. The segmentation results are shown as a label map (blue) and a 3D model (3D view)

Module Description

Image segmentation of the spinal cord and the cerebro-spinal fluid in T2-weighted MRI images. The SpineSegmentation module implements a model-based pattern recognition algorithm for fully automated segmentation.

Usage

Use Cases, Examples

This module is especially appropriate for this use case:

• Automated segmentation of MRI of the spine is critical during minimally invasive intervention when frequent acquisitions of intra-operative images prevents the manual segmentation of the image by an expert. The SpineSegmentation module provides a solution to reduce the burden on the radiologist.

Examples of the module in use:

• Image-guided surgery for the treatment of disk herniation

Tutorial

• Sample Data Set

The sample data sets MRI_Spine.mhd and MRI_Spine.zraw are available at the link below. You will need to create a username on http://nitrc.org. Then log onto nitrc.org and click on the link below. Right-click on MRI_Spine.mhd and MRI_Spine.zraw to copy those files to your local directory.

Below are the step-by-step instructions to load, process and save some sample data (see link above).

Step 1.

Load the sample data

1. load the sample data

Step 2/9.

Select the SpineSegmentation module.

2. select SpineSegmentation module

Step 3/9.

Select the input image.

3. select input image

Step 4/9.

Create a Slicer node for the output image.

4. create image node

Step 5/9.

Create a Slicer node for the output model

5. create model node

• Step 6/9.

Apply the segmentation algorithm

6. apply algorithm

• Step 7/9.

Review segmentation result. The sliders on the top of each 2D view allows for reviewing the segmentation result overlaid on the input image.

7. review result

• Step 8/9.

Save result image and model. The output image and the 3D model can be saved using the Slicer user interface.

8. save results

• Step 9/9.
