Machine Learning and 3D Image-Based Modeling for Real-Time Body Weight and Body Composition Estimation During Emergency Medical Care: Study 2

The goal of this prospective crossover simulation study is to evaluate the accuracy and usability of a 3D camera weight estimation system during simulated emergency care in adult simulated patients, when used by emergency physicians. The main questions the study aims to answer are: * to evaluate the accuracy of 3D camera weight estimation during simulated emergency care, when compared with standard methods * to evaluate the usability of 3D camera weight estimation during emergency care, when compared with standard methods * to evaluate the inter-user reliability of 3D camera weight estimates Volunteers for simulated patients will be required to have anthropometric measurements, a DXA scan, and 3D camera weight estimates. Physician volunteers will need to participate in simulated emergency scenarios during which weight-based therapy must be administered. There will be no interventions.
