Home < Validation of Defined Regions of Interest Using Surface ScanningObjective:
- 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
