Objective To construct an evaluation model system for dynamic data acquisition methods of medical imaging equipment in hospitals. The analytic hierarchy process (AHP) of multi-criteria decision analysis method was used to study the model.

Methods The evaluation index system of dynamic data acquisition technology of medical imaging equipment is constructed from the aspects of reliability and traceability of data acquisition, interactivity of acquisition mode and extensibility of application analysis through multi-criteria decision analysis.

Results A hierarchical evaluation model of dynamic acquisition technology for medical imaging equipment was constructed, which includes 5 primary indexes, 14 secondary indexes and 38 tertiary indexes.

Conclusion We constructed a qualitative and quantitative evaluation index for the dynamic acquisition technology of medical imaging equipment, in which the weight of the quantitative index "reliability" was 30%, the weight of the qualitative index "security", "traceability", "interactivity" and "scalability" were 25%, 20%, 15% and 10%, respectively. It can be used to study the methods and technical characteristics of three kinds of dynamic data acquisition of medical equipment, and form a technical evaluation scheme of dynamic data acquisition.
