Patent Images

1. A method of utilizing an eye movement detection apparatus in a medical application, the medical application being a radiological application which obtains medical images by at least one of a magnetic resonance imaging (MRI) device, a computerized tomography (CT) imaging device, or an X-ray device, wherein during review and interpretation by a user of the medical images obtained during the radiological application, the user follows a predetermined set of visual and cognitive steps, the method comprising:

  • measuring eye movements, including how an eye moves from one location to another, of the user using the eye movement detection apparatus, the eye movement detection apparatus having an optical recording system with a sensing device, said optical recording system being mounted on a user'"'"'s headband and emitting infrared light which is reflected into a charge-coupled camera disposed next to said sensing device, and recording said eye movements;

    providing a computer system which is connected to the eye movement detection apparatus;

    receiving inputs from the user via said computer system, said inputs which are used by a processor of said computer system, to calibrate the eye movement detection apparatus to said user;

    performing said predetermined set of visual and cognitive steps using the eye movement detection apparatus on a plurality of said medical images presented to said user on a display of said computer system, and storing information from said steps into a database to establish a baseline for said user;

    determining a visual profile of a workflow of the user using an analysis of said stored information from said predetermined set of visual and cognitive steps, using said processor;

    creating, using said processor, an automated visual display protocol of said workflow of said user, which is user specific, is stored in said database, and is provided on said display, such that said user can review said medical images using said automated visual display protocol;

    storing in said database, eye-tracking commands inputted into said computer system from the eye movement detection apparatus, for individual user navigation and computer interactions;

    storing context-specific eye-tracking commands from said user with respect to the medical application, which are inputted from the eye movement detection apparatus, into said database of said computer system;

    performing the medical application on said medical images on said display of said computer system, using said eye-tracking commands; and

    storing eye-tracking data and results of an analysis performed by said processor, of data from performance of the medical application on said medical images, in said database.
