Purpose: With technical issues regarding EPID cine based DIBH monitoring being addressed elsewhere, this work focusses on the optimisation of the user interface of the software. Due to the high patient throughput and treatments that demand a significant amount of attention and focus by the radiation therapist radiation therapy departments have a strong need for an IT infrastructure that integrates well with the daily routine workflows. During DIBH treatments radiation therapists treating the patient are (literally) faced with multiple monitors and displays that require their attention and/or input.
Methods: Fundamental graphical user interface (GUI) design principles from the software industry have been applied: clarity, conservation of attention, keeping user in control, one primary screen per action, keep secondary actions secondary, provide natural next step, appearance follows behaviour, consistency, strong visual hierarchies and smart organization. A team of physicists, computer scientists and radiation therapists treating breast cancer patients with DIBH has simplified and redesigned the interface of the previously presented prototype software, which had provided the basic functions necessary to monitor DIBH treatments, to clearly show the essential information while eliminating unnecessary elements.
Results: The redesigned GUI gives patient identifying information and prominently shows the current status of the breath-hold and a trace of the breath-hold depth throughout the treatment. The dialog about the GUI also unveiled opportunities to further optimize the software by including automatic gantry angle detection, reducing the number of interactions with the software needed from the therapists.
Conclusion: Designing a software interface that features enough information to safely perform the job and emphasize the important details is not only desirable but essential for radiation therapy delivery. The process needs to be done in several iterations until a mature product has been created.
