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.
