Abstract
An optical imaging system utilizes a three-dimensional (3D) light scanner to capture topography information, color reflectance information, and fluorescence information of a target object being imaged, such as a surgical patient. The system also utilizes the topography information of the target object to perform an image mapping process to project the captured fluorescence or other intraoperative images back onto the target object with enhanced definition or sharpness. Additionally, the system utilizes the topography information of the target object to co-register two or more images, such as a color image of the target object with a fluorescence image for presentation on a display or for projection back onto the target object.

An optical imaging system to image a target object comprising:
- a light emitter module configured to illuminate the target object with light;
- and
- an image detection module configured to capture a three-dimensional (3D) topography image of the target object when emitted light is emitted from the target object when illuminated by the light emitted by the light emitter module;
- a fluorescence detection module configured to capture a fluorescence image of the target object when fluorescence is emitted from the target object when illuminated by the light emitted by the light emitter module;
- and
- a controller configured to:
- instruct the image detection module to capture the 3D topography image and the fluorescence detection module to detect the fluorescence image of the target object intraoperatively,
- co-register topography information intraoperatively detected from the 3D topography image and fluorescence information detected from the fluorescence image to simultaneously display intraoperatively the co-registered topography information and the fluorescence information to the user via a display.
An optical imaging system to image a target object comprising:
- a light emitter module that includes at least one projector and is configured to illuminate the target object with structured light;
- and
- an image detection module configured to capture a three-dimensional (3D) topography image of the target object when reflected light is reflected from the target object when illuminated by the structured light emitted by the light emitter module;
- a filter that is configured to filter the captured 3D topography image based on a field of view of the image detection module;
- a preoperative image detection module configured to capture a preoperative image of the target object before the target object is positioned to be illuminated by the light emitter module with light;
- a tracking module that is configured to track a position of the target object;
- and
- a controller that includes at least one graphics processing unit (GPU) and is configured to:
- instruct the image detection module to capture the 3D topography image of the target object intraoperatively,
- co-register topography information detected from the 3D topography image intraoperatively and preoperative image information detected from the preoperative image detection module to generate co-registered topography information and preoperative information, wherein the co-registered topography information and preoperative information is segmented to isolate an organ of interest and registered using surface-based registration, and
- display intraoperatively the co-registered topography information and the preoperative image information to the user via a display.
