Primary Outcome Measures:
  • To develop a new type of electronic hand held device, that will demonstrate the image quality comparable to existing devices based on optical techniques. [ Time Frame: 2002-2011 ]

Enrollment: 13
Study Start Date: September 2002
Study Completion Date: December 2011
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A
Ultrasound Imaging of fingertips
Procedure: Ultrasound
Ultrasound scanning of fingertips for assessment of possible imaging modes with Gray scale ultrasound, color flow vascularity imaging, and color flow vascularity imaging before and after exercise.

Detailed Description:
To develop a hand held touch-pad device for identification of individuals, to help with banking and, possibly for detection of anxiety. This is done by their fingerprint and, other digital anatomy and vascular biometrics.
