Abstract Objective To understand the implementation of the current “Specification for testing of quality control in helical tomotherapy unit (WS 531—2017)” and the scientific, practical, advanced and operable issues in the implementation processby the relevant personnel oftechnical service institutions, and so as to provide a scientific basis for the further revising the standard.Methods According to “guideline for health standards tracking evaluation (WS/T 536—2017)” and the implementation plan of the project, questionnaire survey was carried out among technical service personnel who used WS 531—2017 to carry out TOMO quality control testing in 15 domestic provinces. The follow-up and evaluation work were carried out by means of pre-survey, field survey, mail, e-mail, etc.Results 30 questionnaires were collected, 28 ofwhich were valid, with an effective rate of 93.3%. The satisfaction of technical service organization with the overall and text format of the standard were 83.1% and 95.7% respectively; 44.0%was familiar with the content of the standard; 78.6% was fully understood with the terms and definitions of the standard. Standard test indicators and the limits of “proficient mastering” was only 22.2%; According to the standard content, “all in according”was 77.8% in the quality control test of TOMO; The main reasons for the problems in the quality control testwere “Low standard popularity" (68.0%), “difficult to reach the standard setting test equipment” (64.0%) and “insufficient understanding standard” (48.0%). At the same time, the personnel of technical service institutions had a low training rate, and the frequency of applying standards was not high.Conclusion The relevant personnel of technical service institutions were satisfied with the text format and overall evaluation of the standard and had a high awareness of the basic situation and content of the standard, but their familiarity with the standard needs to be improved. Further training, publicity, the operability and scientific aspectsof the standard need to be further strengthened.
