Abstract
An illumination system for a lighting assembly comprises a light assembly configured to selectively illuminate an operating region in a surgical suite and a plurality of light sources positioned within the light assembly and configured to emit light. The system further comprises at least one imager configured to capture image data and a controller. The controller is configured to scan the image data in at least one region of interest for a shaded region and identify a location of the shaded region within the region of interest. The controller is further configured to control the light assembly to activate at least one of the light sources to emit light impinging on the shaded region within the region of interest.
Core Innovation
The disclosure describes a surgical-suite adaptive illumination system that includes light assemblies with multiple light sources, one or more imagers, and a controller. The controller uses image data to adapt illumination in an operating region of a surgical suite by selecting which light sources to activate, and scanned image data is used to determine a region of interest within the operating region.
The controller identifies and locates the region of interest comprising at least one of a shaded region and a contaminated region. After locating the region of interest, the controller controls the light assembly to activate at least one light source so that light impinges on the region of interest.
The disclosure further describes optional depth-based object or depth-map processing, adaptive shadow mitigation using infrared dot projection, and detection and targeted sterilization using wavelength-specific germicidal or UV-based emissions. Controllable, steerable illumination modules are described with track and head actuators and controller memory routines for light control, image analyzing, disinfection, and shadow mitigation.
Claims Coverage
The provided independent claims are clm-00001 and clm-00018. Across these, the claims cover a coordinated illumination system with two inventive features: image capture and controller analysis for selective light activation, and a wearable device with a light source and guidance system coordinated with an imager and a controller.
Wearable device with light source and guidance system with coordinating imager and controller
At least one wearable device comprises at least one light source and a guidance system; at least one imager in communication with the wearable device captures image data; at least one light assembly communicates with the guidance system; and a controller communicates with the imager and the light assembly.
Imager-scanned region of interest including shaded and contaminated regions for targeted activation
A light assembly selectively illuminates an operating region in a surgical suite; the light assembly accepts at least one light source; at least one imager captures image data; and a controller scans the image data for a region of interest comprising at least one of a shaded region and a contaminated region, identifies a location of the region of interest in the operating region, and controls the light assembly to activate at least one light source to emit light impinging on the region of interest.
Together, the independent claim coverage centers on a controller-coordinated illumination system that uses captured image data to identify and locate a region of interest, including shaded and contaminated regions, and then selectively activates light sources so illumination impinges on the region of interest. A further independent claim aspect includes a wearable device with a light source and a guidance system coordinated with an imager and a controller.
Stated Advantages
Adaptive illumination in a surgical suite by scanning image data and activating selected light sources for a detected region of interest.
Mitigation of shaded regions by detecting shadows and adapting illumination accordingly.
Ability to detect and address contaminated regions using targeted illumination and/or detection or sterilization emissions as described.
Documented Applications
Surgical-suite and operating-region illumination where illumination is adapted based on image data to target shaded and contaminated regions.
