Abstract:
The present invention relates to a method for operating a computer device with user's eye movement. The method comprises the steps of detecting the user's eye movement, analyzing the user's eye movement to specify an eye movement pattern in the detected user's eye movement and a time period for completing the eye movement pattern, determining a command associated with a combination of the eye movement pattern and the time period and operating the device according to the command.
Abstract:
A system (1), in particular for image-guided surgery, comprising: at least two display devices (2, 3); a position de-terminator (8) for determining the relative position of the display devices; and an image generator (9) for generating images, which are to be displayed by the display devices, in accordance with the determined relative position.
Abstract:
A system for selectively disabling a surgical instrument operating in a surgical site of a region of interest of a living subject. In one embodiment, the system includes means for noninvasively placing a number of fiducial markers in an anatomic space of the region of interest of the living subject, means for pre-operatively measuring a location of each fiducial marker in the anatomic space, an imaging acquisition device for pre-operatively acquiring an image volume from the region of interest of the living subject, a probe for intra-operatively monitoring a location of the surgical instrument in the anatomic space, and a controller configured to perform the steps of identifying a centroid of each fiducial marker in the image volume, registering the identified centroid of each fiducial marker in the image volume to the measured location of the corresponding fiducial marker in the anatomic space to determine a registration transformation, mapping the monitored location of the surgical instrument in the anatomic space onto a corresponding location in the image volume by an inverse of the registration transformation, and generating a signal to disable the surgical instrument when the mapped location of the surgical instrument is substantially close to a boundary of the surgical site of the region of interest in the image volume.
Abstract:
A control system to control an operating room lamp to generate light to illuminate a surgical site includes an image signal input to receive an image signal from a video camera to capture an image of a surgical site and a control signal output to emit to the operating room lamp a control signal to control at least either a direction or an intensity or a spectral characteristic of the light or a size or shape of the area illuminated by the light. The control system is configured to recognize a hand area of medical personnel and to generate the control signal depending on the image signal and to emit it to the control signal output.
Abstract:
A method and a device for optimizing the image display on imaging apparatuses register whether an operator is looking at the imaging apparatus. The image display of the imaging apparatus is optimized, when it is registered that the operator is looking at the imaging apparatus and namely by dimming the room lighting and/or by increasing the contrast of the imaging apparatus.
Abstract:
An object observation system of the present invention has an observation apparatus for observing a body to be examined, a three-dimensional image recording apparatus for recording three-dimensional images, which are obtained in advance, of the body to be examined, and an image constructing apparatus for constructing a three-dimensional image based on images in synchronization with the observation apparatus, which are recorded in the three-dimensional image recording apparatus.
Abstract:
Certain embodiments of the present invention provide methods and systems for identification of most read images. Certain embodiments provide automatically determining a reading time for an image based on at least one of image viewing time and tool usage with respect to the image, and generating a viewing order for the image based on the reading time. Reading times may be determined for a plurality of images. In certain embodiments, a priority may be assigned to the image based on the reading time. Images may be arranged on a display based on the priority, for example. A series of images may be ordered according to reading time for each of a plurality of images, for example.
Abstract:
Certain embodiments of the present invention provide a method and system for improved identification of significant images using visual tracking. Certain embodiments of the system include a visual tracking system capable of tracking a user gaze with respect to a display device and a significant image selector for identifying at least one significant image based on user viewing time. The visual tracking system identifies an image at which a user is gazing records a viewing time during which the user is looking at the image. In an embodiment, the visual tracking system records viewing times for one or more users. In an embodiment, meta-data is associated with one or more significant images to identify the images as significant images, for example. The system may further include a database or table storing significant image information.
Abstract:
Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.
Abstract:
An endoscope system includes an endoscope, a display, one or more sensors, and a control system. The display is configured to display image content captured by the endoscope. The one or more sensors are located in a headrest and configured to detect an input at the headrest. The control system is configured to receive one or more sensor signals from the one or more sensors and adjust the image content displayed by the display in response to the one or more sensor signals. The one or more sensor signals indicate movement of the headrest with respect to a support on which the headrest is mounted or pressure applied to the headrest
