简要总结
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.
详细描述
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.
