Abstract：Objective To investigate the development status of CT and low-dose X-ray machines in hospitals of different levels in China and understand the demand of relevant practitioners for CT and low-dose X-ray equipment in clinical and scientific research work, so as to provide reference and theoretical basis for the future development of domestic CT and low dose X-ray equipment. Methods An expert group composed of imaging diagnostic doctors, medical engineers and statistical experts was used to study and draw up The Questionnaire of CT and Low-dose X-ray Machine Demand by Delphi method to investigate the clinical needs of medical imaging practitioners in different levels of hospitals in China. Results A total of 505 valid questionnaires were collected from 121 hospitals at all levels in 28 regions of China through random sampling survey. The results show that clinicians have higher requirements on no motion artifact and clear boundary, and pay more attention to the low dose requirements of the equipment|equipment engineers have more emphasis on the utilization rate, failure rate and troubleshooting speed of the equipment| technicians
have higher requirements on operation simplicity, rapidity and compatibility expansion. Conclusion Currently, the demand in China for CT and low-dose X-ray machines is high in terms of hardware, maintenance, professional training, clinical indicators, etc. Domestic CT and low-dose X-ray machines focus on the specific needs of users for product design and service.
