Study on establishing a project concerning the process quality control of treating liver cancer with CyberKnife / 生物医学工程学杂志

ABSTRACT

In order to guarantee the safety and accuracy of the whole treating process as well as better link up of each section during the treatment, we did research in order to establish a project concerning the process quality control (PQC) of treating liver cancer with CyberKnife. From the safety and accuracy point of view, we divided the whole process of treating liver cancer with CyberKnife into ten links, i.e. the registration of patients' information, the im plantation of fiducial markers, fixation of body posture, CT localization, target delineation, design of the treatment plan, quality assurance in physics, implementation of the treatment plan, inspection on the correctness and data archiving. We analyzed the possible mistakes in each link and the consequences brought by them. To smoothly connect all the links, a special part "Attention" was added between every two links. Various wrong operations which may influence the safety and accuracy of treatment were illustrated, and the consequences brought by them were also ex plained. The "Attention" part among links offers important information for the next step, and gives us reminding and warnings. The project of quality control covers all the important links when treating liver cancer with Cy berKnife. It offers regulations, reminding and warning for us so that the safety and accuracy of treatment can be guaranteed, and the work of all staff could be closely connected.
