About

This study is being done to test whether a HealthReel computer vision-based software application can estimate body fat percentage with equivalent accuracy to a whole body dual energy x-ray absorptiometry scan.

Full description

This study is being done to test whether a computer vision-based software application can estimate body fat percentage with equivalent accuracy to a whole body dual energy x-ray absorptiometry scan. The dual energy x-ray absorptiometry scan involves lying on a machine for about 6-10 minutes. It is an open design. The study will also examine whether waist circumference measurement improves the accuracy of the body fat percentage estimate by the computer vision-based application.A total of approximately 492 subjects are planned to take part in this study at one study center.

Enrollment: 492 patients

Sex: All

Ages: 18 to 100 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Male or female, age > = 18 at time of signing informed consent
• Have access to and ability to use a smart phone to take a 15 second video from their home

Trial design

492 participants in 1 patient group

Computer Based Vision

Description:

A 15 second long video will be obtained at the research site using a smart phone or tablet. Then subjects will undergo a whole body dual energy x-ray absorptiometry scan . Then the subject will go home and take a second 15 second long video. The videos will then be analyzed by computer based vision application and the body fat percentage measured by dual energy x-ray absorptiometry scan will be compared.

Treatment:

Diagnostic Test: Computer based vision application by video

Radiation: whole body dual energy x-ray absorptiometry scan
