Home < Validation of Defined Regions of Interest Using Surface Scanning

Objective:

  • To evaluate manual and automated segmentation routines using surface scans of disected bones from cadaveric specimens

Progress:

  • CT images of the hand and wrist have been obtained
  • Four hands have been disected and bones extracted
  • Surface scanning for these disected bones is completed using a Roland LPX-250 Laser Scanner
  • Manual tracing of the CT images is completed
  • Evaluate reliability of the manual tracers is complete using relative overlap
  • Tools have been developed to reorient surface axes and to register the manually defined model and the surface resulting from laser scanning
  • Distance maps for the manual segmentation have been generated.
  • The effect of various post processing routines have been studied relative to changes in the surface geometry relative to the laser scan.


To Do:

  • Complete manual tracing from the CT images
  • Evaluate reliability of the manual tracers
  • Run Neural network segmentation and EM Segmenter on the CT scans
  • Compare the results to the surface scans

Key Investigators:

  • Iowa: Nicole Grosland, Vincent Magnotta, Nicole DeVries
