Greg Wempe
Advised by:
Dr. Robert L. Galloway, Ph.D.
Mr. Steven L. Hartmann
Initial Presentation January 17, 2001

2. Project Definition Design a sheath and carriage system that will
integrate into the present software package
and allow for the tracking and marking of
desired points. Additional software coding
may be required for proper incorporation.
