A New Human-Monitor Interface For Interpreting Clinical Images

Tech ID: 30021 / UC Case 2014-965-0


UCLA researchers in the Department of Radiological Sciences have invented a novel interactive tool that can rapidly focus and zoom on a large number of images using eye tracking technology.


With the development of digital workstations, radiologists have had to move from reading clinical images of 3D anatomy on film in incremental slices placed side by side to reviewing images in a stack mode, scrolling through them individually using a mouse or jog-wheel. In many instances, this shift has resulted in a loss of efficiency for some experts who could previously scan a collection of images for points of interest quickly. Easy and rapid access to large sets of radiological images, as was done before the advent of digital workstations, is necessary and highly sought by expert users.


Dr. Enzmann and his research team have developed a novel human-monitor interface capable of cycling through large sets of images and identifying points of interest using an eye-tracking self-selection mechanism. This technology is designed to run on a large and ultra-high resolution screen, where a large number of images can be displayed side by side and still allow for sufficient image resolution to anatomically localize and identify main features of images. This system supports dynamic magnification (zooming in and out) either automatically through eye tracking or triggered via a key or foot pedal. Points of interest can be rapidly identified, marked, tracked, and revisited and the system can automatically pull other sets of images around the region, enabling the user to rapidly review and switch between images around the same region.
