Abstract

Gaze visualization has been used in the medical field to understand how radiologists read medical images. While prior works were mainly based on diagnoses with a single image, recent works focus on diagnoses with consecutive cross-sectional medical images acquired from preoperative computed tomography (CT) or magnetic resonance imaging (MRI). Such images have distinct characteristics that hundreds of them are from a single exam composing a natural 3D spatial structure. Radiologists have to scroll through a stack of the images for a diagnosis, resulting in more complicated gaze patterns to visualize. Little work has been done on visualizing such gaze patterns for contiguous cross-sectional medical images. We present an interactive 3D gaze visualization, where InfoVis and SciVis techniques are harmonized to show the abstract gaze data along with a realistic 3D rendering of the visual stimuli (i.e. organs and lesions).

Support

This work was supported by the National Research Foundation of Korea (NRF) grants funded by the Korea government (MSIP) (No. 2011-0030813, NRF-2013R1A1A3006706), by the grant No. 02-2013-055 from the SNUBH Research Fund, and by the Interdisciplinary Research Initiatives Program funded by College of Engineering and College of Medicine, Seoul National University (2013). The ICT at Seoul National University provided research facilities for this study.
