The evolution of computed tomography (CT) and its user interface: A contextual and comparative analysis of some of the most used solutions

Abstract

The study presented in this paper was aimed at analyzing the user interfaces of Computed Tomography (CT) scanners and comparing three different systems used in two hospitals in Tuscany, Italy. Heuristic evaluations were conducted to measure the level of usability of these systems. The results show that the three systems have similar, but not equal, usability, that they rely heavily on operators’ competences, and are not designed and implemented to facilitate the execution of complex tasks.
