A questionnaire survey was performed to investigate the different knowledge of radiation exposure, awareness and expectation for O-arm imaging system between the users (orthopaedic surgeons) and the developers (engineers). A total of 93 orthopaedic surgeons and 19 engineers participated and answered the questionnaire consisting of 18 items designed for this study. The items were focused on knowlege, awareness, and expectation. Orthopaedic surgeons had higher scores for items of knowledge domains regarding radiation exposure than the engineers while the engineers were more sensitive to radiation hazards and adopted higher levels of radiation protection than orthopaedic surgeons in the awareness domain. Most engineers and orthopaedic surgeons answered that the requirements of diagnostic and intraoperative imaging systems differ. Image resolution, a low radiation exposure, and the time required for image acquisition was the top three requirements of O-arm selected by engineers. On the other hand, the top three requirements according to orthopaedic surgeons were; image resolution, expediency, and spatial occupancy. User requirements need to be reflected in developing O-arm along with basic requirements such as image resolution and low radiation exposure.
一项问卷调查研究了使用者（骨科医生）和开发者（工程师）对 O 臂成像系统的辐射暴露相关知识、认知和预期的差异。共有 93 名骨科医生和 19 名工程师参与并回答了为这项研究设计的 18 个项目的问卷。这些项目集中在知识、认知和预期方面。骨科医生在辐射暴露相关知识领域的得分高于工程师，而工程师在认知领域对辐射危害更敏感，并采取了比骨科医生更高水平的辐射防护措施。大多数工程师和骨科医生认为诊断和术中成像系统的要求不同。工程师选择 O 臂的前三个要求是图像分辨率、低辐射暴露和获取图像所需的时间。另一方面，根据骨科医生的要求，前三个要求是：图像分辨率、便捷性和空间占有率。用户需求需要在开发 O 臂时得到体现，除了图像分辨率和低辐射暴露等基本要求外。
