Brief summary

The purpose of this study is to develop a small, easily used device to detect a person's blood flow in their fingertips.

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.

Interventions

PROCEDUREUltrasound

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.
