“…They are not monoliths designed by a single manufacturer, but are composed of multiple software solutions with varying degrees of interoperability. Software products may lack features desired by the user or have limited capacity for modification (1,4,7,8).…”

“…Even if the final product of the radiologist's labor is communicated in two words (such as "macro normal"), a computer interface requires further effort. These activities include reacting to dialog boxes, entering passwords, and completing more complex interactions that require navigating electronic medical records (EMRs) (3,4). Because a radiologist's work is repetitive, these small tasks combine to become a significant factor in loss of productivity, user dissatisfaction, fatigue, and injury (5)(6)(7).…”

Radiologists rely heavily on the digital radiology workstation. They spend most of their time interacting with software applications that use multiple input devices, including mice, keyboards, and microphones. The efficiency of this relationship depends on the interface of the different software applications, their interoperability, and input device effectiveness. Because of the repetition of a radiologic workflow, even small inefficiencies can accumulate into significant losses of time and productivity and contribute to user fatigue. Alternative input devices (AIDs) with onboard memory can be used as ergonomic human-computer interfaces. These devices can also be coupled with AutoHotkey scripts to complete complex tasks in one keystroke. Radiologists can use modern AIDs and simple scripts to minimize frustration, improve and personalize their routines, and streamline interactions with the workstation. The authors discuss hardware and software features that do not require support from information technology professionals and can be implemented with any software that relies on user input.

“…In addition, their duty is carried out in a highly demanding clinical environment, where both image quality and patient throughput are to be maximized; this has the consequence of minimum (or null) scanner time allocation for training. Moreover, the software installed in these machines poses additional difficulties, even for experienced radiologists [ 2 ].…”

Magnetic resonance is an imaging modality that implies a high complexity for radiographers. Despite some simulators having been developed for training purposes, we are not aware of any attempt to quantitatively measure their educational performance. The present study gives an answer to the question: Does an MRI simulator built on specific functional and non-functional requirements help radiographers learn MRI theoretical and practical concepts better than traditional educational method based on lectures? Our study was carried out in a single day by a total of 60 students of a main hospital in Madrid, Spain. The experiment followed a randomized pre-test post-test design with a control group that used a traditional educational method, and an experimental group that used our simulator. Knowledge level was assessed by means of an instrument with evidence of validity in its format and content, while its reliability was analyzed after the experiment. Statistical differences between both groups were measured. Significant statistical differences were found in favor of the participants who used the simulator for both the post-test score and the gain (difference between post-test and pre-test scores). The effect size turned out to be significant as well. In this work we evaluated a magnetic resonance simulation paradigm as a tool to help in the training of radiographers. The study shows that a simulator built on specific design requirements is a valuable complement to traditional education procedures, backed up with significant quantitative results.

“…Better thinking aloud could have generated more insights into "why to use which user interface element at a certain location". Generally, as stated by Jorritsma (2016), user interaction log data analysis in usability evaluation can be used for guiding other sources of data collection. For example, the log data analysis in this evaluation has found a more frequent use of the map view to retrieve POI information than using the AR view.…”
