RESUMO
It is an important technical means to ensure that the radiodiagnosis and radiotherapy equipment can be put into use normally to carry out acceptance test after the newly installed, maintained or replaced important components. Health inspection found that medical institutions are often easy to ignore the acceptance test in the process of use, and do not carry out acceptance test on the radiodiagnosis and radiotherapy equipment after maintenance or replacement of important components. However, it is difficult to ask medical institutions to correct them without the definition and scope of ‘important components’ according to laws or technical standards. This paper studies and discusses the definition of ‘important components’ of radiodiagnosis and radiotherapy equipment, and puts forward some suggestions onthe practical application of the research results.
