Back to 2010 AHM agenda
Introduction
- This is the first in a series of challenges which aim at improving our set of robust interactive segmentation tools.
The Challenge
- Provide a tool in 3D Slicer which will segment vertebrae. It is expected that each vertebra is individually and fully labelled.
- the algorithm can be developed using the data below
- the algorithm will be tested using a different ct data set of comparable quality.
- The algorithm can be semi-automated. It is acceptable to ask the user to point to one or more vertebrae or other structures.
- The algorithm must comply with "Rons Rules For Tools".
Deliverables
- Deliver your solution to Ron (contact by email) by May 31 2011
- Plug-in for Slicer
- Directions on how to use
- The best solution will be awarded a prize of USD 500.-
- Definition of "best":
- Compliant with Rons Rules for Tools
- Outer boundaries of the vertebral body correspond to the visible boundaries
- Clean separation from adjacent vertebrae, ribs (if present) and intervertebral disks
- Full segmentation of the transverse, spinous, and other processes
Sample data set
- See volume of interest which is cropped from the full data set. For reference, L1 has been labeled. Use File/Load scene to load the volume into Slicer. The size of the download is 70MB and contains the original data set as well.
- The bottom case in this table is the original location.
- Lung CT data set: This is a data set from a different subject.
- Lung CT data sets (3 cases) with COPD: These are three subjects with different degree of COPD.
Atlas reference
If you need anatomical knowledge, please download [1] which contains some individually labeled vertebrae.
