Human-Centered Design of Image-Guided Interventions for Minimally-Invasive Surgeries: Toward a Methodology

Abstract

Image-guided interventions are used increasingly in medical procedures, particularly in minimally-invasive surgery (MIS). Despite the benefits of such technologies for patients, there are drawbacks for surgeons. These include reduced field of view (FOV), aperture viewing, and passive viewing. We measured the impact of specific features of imaging devices on tasks relevant to MIS. Results suggest that (a) impairments in navigation due to reduced FOV can be moderated with methods that help users develop mental models of three-dimensional space; (b) illusions of motion due to aperture viewing can be moderated by manipulating properties of the aperture; (c) active control may result in better navigation than passive viewing. Our results suggest several avenues to pursue toward the aim of improving image-guided interventions.
