Volume rendering of the spine in the challenge data set

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 using the Slicer license
    • 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
    • During the test phase thoracic or lumbar vertebrae will be used. The cervical spine is excluded
    • 2-3 vertebrae will be segmented to evaluation

Sample data set

Individual vertebrae have been manually segmented in the abdominal atlas

Atlas reference

If you need anatomical knowledge, please download [1] which contains some individually labeled vertebrae.


To learn about regional differences among healthy vertebrae see the following wikipedia entries:
