Abstract:Visual search is a task that is performed in various application domains. We examine it in the domain of radiological analysis of 3D vascular images. We compare several major visualisations used in this domain, and we study the possible benefits of automatic warning systems that highlight the sections that may contain visual targets and hence require the user’s attention. With help of a literature study, we present some theory about what result can be expected given the accuracy of a particular visual cue. We present the results of two experiments, in which we find that the Curved Planar Reformation visualisation, which presents a cross-section based on knowledge about the position of the blood vessel, is significantly more efficient than regular 3D visualisations, and that automatic warning systems that produce false alarms could work if they do not miss targets.
