Whole-body three-dimensional photonic scanning: a new technique for obesity research and clinical practice.
Information on body shape has long been used in categorizing and monitoring obesity. Alongside abdominal circumferences, recent studies further emphasize the value of indices such as sagittal diameter adjusted for thigh girth in categorizing cardiovascular risk. Whole-body three-dimensional photonic scanning has rapidly emerged as a new technology for digital anthropometric measurement. Photonic scanners capture sophisticated raw data on body surface topography in a few seconds, from which extensive body shape information can be extracted using computer algorithms. Photonic scanning now has the potential to play a key role in (1) categorizing obesity (including childhood screening), (2) ranking abdominal size and shape in large-scale epidemiological studies, (3) monitoring individual patients to evaluate treatment efficacy and (4) estimating surface area for drug dosage calculations. New statistical modeling techniques offer the opportunity to develop novel parameters of body shape for linking with biological health outcomes. The low cost, accuracy, ease of use and high acceptability of the technique make it highly suitable for both research and clinical applications.
