Presentation Transcript

  1. Segmentation and Visualization of Intervertebral Discs Preliminary Presentation EyalBar-Kochba ENGN2500: Medical Imaging April 12th, 2011

  2. The Roadmap To Intervertebral Disc Segmentation

  3. A Primer On Intervertebral Discs Anatomy of the Spine T2-weighted MR sagittal image ● Normal Disc ● Degenerated intervertebral disc with disc herniation

  4. Why Segmentation Is Not So Simple. Zoomed T2-weighted MR sagittal image Segmentation issues: ♦ Gray-level overlapping of the nucleus pulposus and vertebrae with gray-level overlapping. ● Gray-level overlapping of the annulus fibrosus, anterior longitudinal ligament, and vascular tissue. ▲ Blurring due to the partial volume effect.

  5. Segmentation Using Atlas-FCM Segmentation method proposed by S.K. Michopoulou, et al. (2008)

  6. Segmentation Using Atlas-FCM Segmentation examples using Atlas-FCM [S.K. Michopoulou, et al. (2008)]

  7. 3D Reconstruction of Segmented Images • Assign unique values to images outside of boundary. • Import data into tecplotand plot isosurface. • Compare data with segmentation produced by V3D. Samples of V3D Visualization [H. Peng, et al. (2011)]
