[Risk assessment in radiation therapy].

Radiation therapy was one of the first medical specialities to implement quality assurance (QA) programs in clinical practice. These QA programs have mainly focused on equipment performance neglecting human factors. Risk management is a relatively new approach in medical disciplines. Methods of evaluation and risk management must be identified, applied and adapted to the specificities of this domain. Based on the experience of industry, risk management will allow us to substantially improve safety and develop our own models of management. Recent experiences use these approaches to implement risk management in radiation therapy departments.
