What is BVI

What is BVI

Based on individual body shape rather than one standard measurement technique for all people, BVI divides the body shape of an individual into sections so that the body volume of the body parts and body composition can be analysed. This allows BVI to differentiate between people with the same Body Mass Index (BMI) rating.

BVI is the world’s first dedicated computer based anthropometric system for obesity and allows a healthcare professional to:

  • Measure a patient in less than 6 seconds without any radiation or intervention whilst being comfortable for the patient
  • Measure the differences in body shape between patients with the same BMI rating or waist circumference.
  • Objectively track an individual’s data over time to assess changes in a patient’s body shape
  • Use a health risk indicator by combining a person’s 3D shape with their medical statistics, height, weight, age and gender

What are the limitations of BMI?

    • BMI was invented almost 200 years ago in 1830 by Belgian statistician Adolphe Quetelet, it was to be used as a broad guide of obesity for public health purposes
    • BMI is a manual measurement calculated by dividing a patient’s weight in kilograms by their height in metres squared
    • The measurement calculation results in 5 broad categories underweight (BMI under 18.5), normal weight (18.5 to 24.9), overweight (25 to 29.9), obese (30 to 39.9), morbidly obese (40+)
    • BMI does not take into account age, weight distribution or the fact that muscle weighs more than fat
    • Healthy, muscular men and women can be incorrectly classified as being overweight under BMI
    • There is no distinction between men and women with different body shapes and heights, but with the same BMI
    • Due to its limitations, healthcare professionals are now using BMI in conjunction with other manual measurements such as waist to hip ratio and waist circumference. However the use of manual measurements only creates another problem – the variancy between the way in which people actually measure the same measurement

The image detailed above shows 8 women all with a BMI of 30, therefore all classified as obese.

However, it is clear that they are all different heights and shapes and carry their weight in different places, some with the majority of weight around the abdomen; the most dangerous to our health. Others have more weight around the pelvis and thighs and less weight surrounding the abdominal area.

Under BVI classification these women would not all be classified as the same, depending on their age and weight distribution their BVI and potential health risks will be different.

How does the BVI scanner work?

A patient walks into the 7ft scanner and is scanned in their underclothes to ensure that the contours of the skin are correctly measured – the system is perfectly safe as no radiation is involved and the whole process takes 2-3 minutes from start to finish.

BVI data is captured using a 3D camera, but in reality is better described as a ‘Human Photocopier’ – copying a perspn’s body shape to get measurements that simply can’t be done by the human hand.

The scan is saved on a secure server anonymously to be accessed by authorised healthcare professionals, takes less than 6 seconds and can extract an infinite combination of measurements for healthcare analysis.

Body Volume Imaging is perfectly safe and uses white light only, reflected on the body to create an exact ‘virtual’ image of a person’s shape and weight distribution.
