What is BVI?
BVI is an acronym for the Body Volume Index. BVI technology is the world’s first system for body volume; specifically measuring total body fat, visceral fat, waist-to-hip ratio, waist circumference as well as providing a unique BVI health indicator number. BVI uses patented 3D technology - the first time an affordable and easily accessible method has been available to professionals to measure body volume.
Who are the developers of BVI?
BVI was developed by Select Research in collaboration with international research and medical organisations, such as Mayo Clinic. BVI America has secured the commercial rights for BVI from Select Research for the US and Canadian regions.
How long did BVI take to develop?
The idea for BVI was conceived at the turn of the millennium and software and clinical development started in 2004. In March 2007 an initial software application using 3D full-body scanners was released and a 12-year R&D program started with Mayo Clinic and the Medical Research Council as the main collaborators. In May 2017 a new mobile application using an iPad was released and this has now been superseded by the new Software Development Kit (SDK), released in July 2019. The new SDK will allow companies to integrate BVI data into their existing platforms and services.
How accurate is the visceral fat measure?
Based upon the validation that has been done and will be published in the Autumn, the accuracy is about 70% against MRI which is the gold standard for body composition analysis.
How accurate is the total body fat% measure?
Based upon the validation that has been done and will be published in the Autumn, the accuracy is about 85% against MRI which is the gold standard for body composition analysis.
How accurate is the waist circumference?
Based upon the validation that has been done and will be published in the Autumn, the accuracy is about 90% against BVI full body scanners and manual measurements using a tape measure which is gold standard for body composition analysis.
How accurate is the waist to hip ratio?
Based upon the validation that has been done and will be published in the Autumn, the accuracy is about 85% against BVI full body scanners and manual measurements using a tape measure which is gold standard for body composition analysis.
How does BVI measure visceral fat just from a smartphone?
BVI has been developed by fusing the data from thousands of 3D body scans which contain volume and linear data and then matching these with MRI data from the same people which have been analysed to calculate visceral and total body fat. For BVI unique algorithms have been created which allow the body shape of a person to be measured and then an indication of their total body fat and visceral fat to be determined. We believe that for BVI, the largest collection of 3D body scan and full body MRI scans in the world have been used to create these algorithms.
Has it involved external collaboration and validation if so by whom?
There have been significant and high profile collaborators involved in the development of BVI over the past 12 years. These have included validation on the following aspects of the BVI technology:-
Waist to Hip Ratio
BVI Total Body Fat to Bio-Impedance
(University of Gloucestershire)
BVI Total Volume to BodPod BVI as a weight motivation tool
Has it received certification and review?
Yes – BVI is certified as a Class 1 Medical Device by the MHRA and has achieved CE Marking throughout Europe. In the US, the FDA has reviewed BVI and considered it to be a ‘general wellness’ product, therefore, allowing for widespread use amongst companies and with patients.
Will there be any more features added in time?
Yes the new BVI number will be incorporated into the BVI and BVI Pro apps in due course and the new Software Development Kit (SDK) will allow for specific integration of the BVI data into existing platforms and devices going forward.
Does the BVI system retain any of our data?
No - all of the data remains with the client and we do not keep any of the data.
Will the SDK be improved in the future?
We are continually working to improve our SDK and updates will be released periodically. Our key priorities include improving the accuracy of the visceral fat and total body fat.
How have the waist and hip measurements been validated?
They have been validated against the 3D BVI full body scanner and also against manual measurements.
How have the visceral fat and total body fat been validated?
They have been validated against full body MRI scans by the University of Westminster and against DEXA by the Mayo Clinic. Both papers are published. Please reach out to us directly to view validation documents.
