Abstract
This study was aimed to establish a body surface area (BSA) database, to derive a height-weight BSA estimation formula, and to revise the normalized segmental body surface area (NSBSA) of Lund and Browder chart based on three dimensional (3D) scan data. For each gender, 135 subjects were drawn. The sampling was stratified in five stature heights and three body weights according to a previous survey. The 3D body surface shape was measured using an innovated 3D body scanner and a high resolution hand/foot scanner, the BSA and segmental body surface area (SBSA) were computed based on the summation of every tiny triangular area of triangular meshes of the scanned surface; and the accuracy of BSA measurement is below 1%. The results of BSA and sixteen SBSAs were tabulated in fifteen strata for the male, the female and the total (two genders combined). The comparison of BSA shows that the BSA of this study is comparable with the Du Bois and Du Bois’ but smaller than that of Tikuisis et al. The difference might be attributed to body size difference between the samples. A new BSA estimation formula,, was obtained. An accuracy test showed that this formula has smaller estimation error than that of the Du Bois and Du Bois’; and significantly better than other six BSA estimation formulae. To revise new Lund and Browder chart, the NSBSA data was used. The comparison of NSBSA shows that the differences of NSBSA between this study and the Lund and Browder chart can be high up to 2.30 %BSA. The new Lund and Browder chart for the Total, the Male and the Female are offered for reference.
