The TomoTherapy® Failure Modes and Effects Analysis (FMEA) Tool is a console based application written in MATLAB that simulates various delivery failure modes by parsing TomoTherapy patient archives, modifying the delivery plan, and recomputing the plan dose using the Standalone GPU TomoTherapy Dose Calculator. Each modified plan dose distribution is then compared using various metrics. Both the failure modes and metrics are customizable through the use of “plugin” functions, as described below.
