About this study
Official title: Finger Imaging and Biometric System
The purpose of this study is to develop a small, easily used device to detect a person's blood flow in their fingertips.
Read the 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.
- Conditions
- Capillary Permeability
- Being tested
- Ultrasound
- Keywords
- vascularity, fingertips
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
UltrasoundProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| A | Experimental | Ultrasound Imaging of fingertips Receives: Procedure: Ultrasound |
What is being measured
The primary outcome is the main question the study is designed to answer.
To develop a new type of electronic hand held device, that will demonstrate the image quality comparable to existing devices based on optical techniques.
Measured: 2002-2011

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 3 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: No longer acruing data for this study.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2015.
