In the practical teaching of large-scale medical equipment courses in medical colleges and universities. There are some problems such as less opportunities for students to operate the equipment which is possessed by teaching hospitals

the large-scale medical equipment in teaching hospitals are in a pathogenic environment

and some equipment such as CT

DR have radiation hazards

which lead to difficulties in practical teaching. These problems restrict the cultivation of students' practical ability

cause disconnections between theoretical teaching and practical teaching

and are not conducive to training new engineering and new medical science talents. So

this paper puts forward an idea which introduces virtual simulation teaching instruments of large-scale medical equipment into the teaching of medical equipment in medical colleges and universities

uses the physical structures

control systems and functional software of virtual simulation teaching instruments to implement the teaching of integration of theory and practice

and also sets up validation experiments

comprehensive experiments

designing experiments and research explorative experiments in the teaching process. This kind of teaching can not only realize the high integration of theoretical teaching and practical teaching

but also consolidate students' basic theoretical knowledge

improve their abilities to solve complex engineering problems

and cultivate new engineering and new medical talents in line with the needs of the new era.
