User Experience of CT Scan: A Reflection of Usability and Exertions

Medical devices follow a trend, just like consumer electronic products, where they are becoming more complicated and performance is doubling every two years. Consequently, medical devices require a multidisciplinary team for design and development. Therefore, with so many commands and systems to deal with, users cognitive loads are challenged to effectively execute commands. In medical devices, the cognitive workload will play more of a role because it uses advanced technology, is extremely expensive and takes a great deal of specialization to operate. Thus, effective and economical methods are required to evaluate user experience. Heuristic evaluation is an effective method to identify major usability problems and highlight issues faced by users. Heuristic evaluation was adapted, to identify the usability of a CT scan on Saudi Arabian users and to identify if operating the CT scan can lead to physical and mental load effort. Contrary to the expected belief that young people are savvy in technology, this study found that this is not the case with CT, but rather working experience is more valuable in encountering usability catastrophic.
