FMECA Application in Tomotherapy: Comparison between Classic and Fuzzy Methodologies

Accident analysis in radiotherapy highlighted the need to increase quality assurance (QA) programs by identification of failures/errors with very low probability (rare event) but severe consequences. In this field, a Failure Mode, Effects and Criticality Analysis (FMECA) technique, used various industrial processes rank critical events, has been met much interest. The literature describes different FMECA methods; however, it is necessary understand if these tools are incisive effective healthcare sector. work, comparisons methodologies risk assessment patients undergoing treatments performed helical tomotherapy reported. modes identified for phases “treatment planning” execution” classified using Risk Priority Number (RPN) index. Differences similarities classification examined approaches highlighted.
