Prediction of Body Surface Area Based on 3-Dimensional Laser Scans

摘要

Treatment of many military-relevant diseases depends on knowledge of body surface area (BSA). ESA is typically estimated using predictive formulae that were developed using a variety of measurement techniques. More recently, techniques to use the 3-D laser scanner to provide precise measurement of ESA have been developed. The objectives of this study are to accomplish the following: (1) collect measurements of ESA from whole-body laser scans, (2) determine the accuracy of currently used ESA estimation formulae based on stature and weight, (3) determine the impact of additional body dimensions on the accuracy of BSA estimation, (4) determine the reliability of ESA prediction from laser scans, (5) determine differences between two scanner types, and (6) develop new models that include use of body circumferences and segment lengths as predictor variables. Objectives (1) through (4) have been completed. The Vitronic Viro scanner provides a reliable method of measuring ESA. ESA prediction from currently used equations provides a satisfactory value. Stature and weight are sufficient to predict ESA accurately. Predictions of BSA from stature and weight do not have to be adjusted for gender. Addition or substitution of other anthropometric variables does not appear to improve predictive accuracy.
