Burn Injury Assessment Tool with Morphable 3D Human Body Models

Abstract : Bum patient outcomes are dependent on the wound surface area as a percent of the total body surface area (%TBSA), bum locations, bum depth, and patient age. %TBSA is essential in determining fluid resuscitation and nutrition support, and surgical intervention and rehabilitation planning. The proposed burn injury assessment software tool is aimed at increasing %TBSA accuracy by improving on both TBSA and bum area estimations. Conventional methods (Rule-of-Palm/Nines and Lund-Browder chart) use a generic 2D body shape diagram to represent the human body which lacks the capability to capture 3D anthropometric variability of actual human body shapes, resulting in inaccurate % TBSA. This burn assessment tool will include an interactive anthropometry based human body generator to create, in real-time, a personalized 3D body shape model that has been morphed according to available subset of adjustable anthropometric measurements (weight, age, gender, height, waist, arms and legs measurements) as stored in most anthropometry databases. To improve on bum area estimations, the bum tool will allow the user to interactively demarcate burn areas of varying severity directly on the personalized 3D model for calculation of% TBSA. Photographic image assisted burn demarcation and Android version of the prototype were developed.
