What is Application of Systems and Control Theory‐based Hazard Analysis to Radiation Oncology about?

## Purpose: Both humans and software are notoriously challenging to account for in traditional hazard analysis models. the purpose of this work is to investigate and demonstrate the application of a new, extended accident causality model, called systems theoretic accident model and processes (stamp), to radiation oncology. specifically, a hazard analysis technique based on stamp, system-theoretic process analysis (stpa), is used to perform a hazard analysis. ## Methods: The stpa procedure starts with the definition of high-level accidents for radiation oncology at the medical center and the hazards leading to those accidents. from there, the hierarchical safety control structure of the radiation oncology clinic is modeled, i.e., the controls that are used to prevent accidents and provide effective treatment. using stpa, unsafe control actions (behaviors) are identified that can lead to the hazards as well as causal scenarios that can lead to the identified unsafe control. this information can be used to eliminate or mitigate potential hazards. the stpa procedure is demonstrated on a new online adaptive cranial radiosurgery procedure that omits the ct simulation step and uses cbct f
