Abstract: 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.
