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.

Condition or disease Intervention/treatment Phase
Capillary Permeability Procedure: Ultrasound Not Applicable

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.

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. 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 ]
