Abstract
The present disclosure provides systems and methods for medical imaging. The system may comprise an optical adapter. The optical adapter may comprise a housing that comprises (1) a first end configured to releasably couple to a scope and (2) a second end configured to releasably couple to a camera. The optical adapter may comprise an image sensor coupled to the housing. The optical adapter may comprise an optics assembly disposed in the housing. The optics assembly may be configured to (1) receive light signals that are reflected from a target site within a subject's body and transmitted through the scope, and (2) reflect a first portion of the light signals onto the image sensor while permitting a second portion of the light signals to pass through to the camera.
Core Innovation
The invention is an optical module with a housing that releasably couples to a scope and releasably couples to a camera. The housing contains an image sensor and an optics assembly, and the optics assembly receives light signals reflected from a target site within a subject’s body and transmitted through the scope.
The optics assembly reflects a first portion of the light signals onto one of the image sensor or the camera while permitting a second portion of the light signals to pass through to the other of the image sensor or the camera. The configuration supports multi-wavelength imaging by splitting the light signals into channels that correspond to different wavelength ranges.
The image sensor is configured to detect wavelengths within a first range, and the camera is configured to detect wavelengths within a second range different from the first range. At least one of the first range or the second range comprises reflected light signals comprising laser speckle from the target site, while reflected visible-band signals from white light are routed to the camera for photographic or video images such as RGB.
Claims Coverage
Only one independent claim is provided in the partial content. It covers an optics module that relays reflected light from a target site through a scope to two different detectors while enabling multi-wavelength imaging using separate wavelength ranges, including laser speckle in at least one range.
Releasable scope-to-camera optical housing for multi-wavelength imaging
A housing configured to releasably couple to a scope and releasably couple to a camera, with an image sensor in the housing and an optics assembly disposed in the housing.
Optics assembly splitting reflected scope-transmitted light for two detectors
An optics assembly configured to receive light signals reflected from a target site within a subject’s body and transmitted through the scope; reflect a first portion of the light signals onto one of the image sensor or the camera; and permit a second portion of the light signals to pass through to the other one of the image sensor or the camera to enable multi-wavelength imaging.
Separate wavelength ranges with laser speckle included in a range
The image sensor is configured to detect wavelengths within a first range and the camera is configured to detect wavelengths within a second range different from the first range, wherein the first range or the second range comprises reflected light signals comprising laser speckle from the target site.
The provided independent claim defines a releasably coupled optical module that uses an optics assembly to split reflected, scope-transmitted light between an image sensor and a camera, enabling multi-wavelength imaging through different wavelength-detection ranges, with laser speckle present in at least one of those ranges.
Stated Advantages
Hardware/software flexibility for imaging architectures including hyperspectral/depth/laser-speckle and related processing.
Dye-free real-time perfusion visualization.
Reduced delays and reduced false positives compared with dye-based ICG angiography.
Documented Applications
Endoscopic or medical imaging using an optical adapter that overlays or combines laser-speckle/perfusion information with RGB/video signals for multi-wavelength viewing.
Real-time perfusion visualization as compared with dye-based ICG angiography.
