clinical anthropometrics and body composition from 3-dimensional optical imaging

Anthropometry is the study of the physical measures of the human body. Height, weight, lengths, skinfold thicknesses, and circumferences are commonly used anthropometric measures that proved to be useful for investigating patients with endocrine and metabolic disorders and for monitoring growth, aging, and body size and composition adaptations elicited by diet and training in athletes1,2. For example, the assessment of waist and hip circumferences proved to be useful for the management of persons with obesity: both circumferences assess the distribution of adiposity that can be considered a predictor of all-cause mortality3.
Limb circumferences are frequently assessed in rehabilitative and sports medicine because of their usefulness for detecting and/or monitoring the decrease in appendicular lean mass (e.g., calf circumference is used as a simple and practical skeletal muscle marker for diagnosing low skeletal muscle and sarcopenia)1,2 and the inter-limb asymmetry that impacts both physical performance and risk of injuries in athletes and quality of life in patients (e.g., cancer patients with unilateral extremity swelling)1,2. Further, a large number of anthropometrics-based body composition prediction models have been proposed over the last several decades to estimate the amount of fat mass or fat-free mass from a combination of different anthropometric measures such as body circumferences or skinfold thicknesses1,2,4,5,6,7.
Because conventional anthropometric (i.e., tape-based and caliper-based) measurements may not be culturally or socially acceptable and also exhibit poor reliability8, there was the need for the development and validation of non-invasive, reproducible, and valid approaches. Recently developed three-dimensional (3D) optical imaging systems enabled to provide non-invasive, precise, and accurate measurements8,9,10,11, as well as digital consumer cameras and smartphones offer easy-to-use and widely available tools suitable to be used in clinical and non-clinical settings to evaluate both patients and healthy subjects8,9,10,11,12,13,14,15,16,17,18,19,20. The aim of the protocol reported in the following section is to describe the procedures for evaluating body size, shape, and composition through two commercially available solutions for 3D optical imaging that became pervasive during the last years both in the healthcare setting (to evaluate patients) and in non-clinical settings (to evaluate athletes).

The scope of our research is the assessment of body size, shape, and composition through innovative technologies for three-dimensional optical imaging. Body composition field is more than 100 years old, and many methods have been extensively evaluated. The most recent advances are in the area of 3D optical imaging, which provides a refined and accessible approach to evaluating body size, shape, and composition.One important question is if 3D optical imaging methods can be successfully implemented on a wide scale, given the importance of proper lighting and attire. Most advanced methods, such as MRI, still have bottlenecks due to the need for automated analysis software. Three-dimensional optical scanning is relatively inexpensive, radiation-free, non-invasive, and faster than other investigations commonly adopted in research and clinical settings for body size and composition assessment.Among the many new questions, the methods we introduce will put forth the question of what body shapes are associated with various disease states and with what genetic mechanisms.

The body size and composition assessment is commonly included in the routine management of healthy athletes as well as of different types of patients to personalize the training or rehabilitation strategy. The digital anthropometric analyses described in the following protocol can be performed with recently introduced systems. These new tools and approaches have the potential to be widely used in clinical settings because they are very simple to operate and enable the rapid collection of accurate and reproducible data. One system consists of a rotating platform with a weight measurement plate, three infrared cameras, and a tablet built into a tower, while the other system consists of a tablet mounted on a holder. After image capture, the software of both systems generates a de-identified three-dimensional humanoid avatar with associated anthropometric and body composition variables. The measurement procedures are simple: a subject can be tested in a few minutes and a comprehensive report (including the three-dimensional scan and body size, shape, and composition measurements) is automatically generated.

The procedures for body size, shape, and composition assessment through commercially available solutions for three-dimensional optical imaging enable the rapid collection of accurate and reproducible data. Clinicians could implement the acquisition of innovative and useful biomarkers (&#34;e-tape&#34; measurements) in routine evaluations of patients to assist in characterizing&#160;their health status.

Generation and Analysis of De-Identified 3D Humanoid Avatars and Automated Anthropometry Using System 1

To begin, instruct the subject to dress in form-fitting garments and wear a swim cap for hair coverage. Measure the height of the subject using a standard stadiometer. Launch the app installed on tablet one.Ensure that the tablet is connected to System One featuring a rotating platform, weight measurement plate, and three infrared cameras. Fill in the subject registration form, including the first name, last name, email address, password, gender, units of measurement, and birthdate. Flag the three check boxes of the acceptance of terms of service agreement, privacy policy, and liability waiver.Then tap the Submit button. After ensuring the subject is wearing a swim cap correctly, tap the Next button. Verify that the subject is wearing proper attire, then tap the Next button.Once the scanner area is clear, enter the subject's height into the height measurement field and tap the Next button. Fill in the additional optional matrices such as heart rate and systolic and diastolic blood pressure. Then tap the Submit button.Instruct the subject to step on the scale and stand still on the footprints with hands at their sides for 10 seconds to measure the body weight. Guide the subject to adopt the standardized A pose while grasping the telescoping handles. For body scanning, lift the handles until the arms and legs are straight.Keep the head still with eyes forward. Press and hold the buttons of the handles until the light coating depth sensors capture the three-dimensional shape. Once the scan is complete, step off the scale and tap the Sign Out button With system one software, a de-identified three-dimensional humanoid avatar transitioning point clouds into a mesh of approximately 25, 000 vertices, and 50, 000 faces were generated.The representative avatars obtained in a male athlete and a person with obesity demonstrated differences in anthropometric measurements and body composition estimates.

Generation and Analysis of De-Identified 3D Humanoid Avatars and Automated Anthropometry Using System 2

To begin, instruct the subject to dress in form fitting garments, and wear a swim cap for hair coverage. Measure the height and weight of the subject using a standard scale with a stadiometer. Using a modern browser on a computer, access the registration dashboard of system two.Fill in the subject registration form, including the first name, last name, phone number, email address, age, gender, weight, and height. Flag the checkbox to accept the terms of use and privacy policy. Then, click the signup button to complete the account setup.Visualize the account view page, showing the subject's unique, quick response code, phone number, and email address. Use a mobile phone to take a photograph of the quick response code. Launch the app installed on the tablet of system two.Touch the screen of the tablet, and show the quick response code. Then, tap the start button. Ask the subject to listen to the audio instructions, and watch the guide provided on the screen.Position the subject on a carpet at a standardized distance from the tablet, with the feet and the feet guide aligned with the green feet marker shown on the screen. Direct the subject to assume the front A pose, with legs separated, and arms abducted from the torso at approximately 45 degrees angle, hands closed into fists, to accurately capture the frontal image. Now, ask the subject to a side pose, with feet together, hands placed straight on the sides, and face straight to capture the lateral image.Once the scan is complete, the app display a thank you screen. With system two software, a more detailed three-dimensional humanoid avatar, converting point clouds into a mesh, with roughly 50, 000 vertices and 100, 000 faces was generated. The representative avatars obtained in a male athlete, and a person with obesity, demonstrated differences in anthropometric measurements, and body composition estimates.
