摘要： A surgical imaging system is described. The system includes first and second optical assemblies. Each optical assembly defines a respective optical axis, and each includes a respective set of one or more optics for adjusting field-of-view (FOV) and focus and a respective camera for capturing an image. The system includes a controller for controlling the optical assemblies and for switching the surgical imaging system between a coupled configuration and an uncoupled configuration. In the coupled configuration, the first optical assemblies are controlled to adjust the respective sets of optics and/or the respective optical axes in dependence on each other. In the uncoupled configuration, the optical assemblies are controlled to adjust the respective sets of optics, and the respective optical axes independently of each other.

摘要： Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.

摘要： A camera system for providing images with simultaneous high resolution and large depth of field is provided. The system includes: a camera device having a field of view, the camera device configured to automatically acquire: a first image of the field of view at a first numerical aperture; and a second image of the field of view at a second numerical aperture smaller than the first numerical aperture; an image processing unit configured to combine the first image with the second image into a single image by: extracting a higher-resolution in-focus portion of the first image; and replacing a corresponding lower-resolution portion of the second image with the higher-resolution in-focus portion of the first image; and, a display device in communication with the image processing unit, the display device configured to render the single image.

摘要： A medical navigation system is provided for acquiring a depth map of a surgical site of interest in a patient. The medical navigation system comprises a camera, a light projecting device, a display, and a controller. The controller has a processor coupled to a memory. The controller is configured to generate a signal provided to the light projecting device to project an edge indicator on the surgical site of interest, generate a signal to operate the camera to perform a focus sweep and capture a plurality of images during the focus sweep where the plurality of images includes the projected edge indicator, receive from the camera data representing the plurality of images captured during the focus sweep, and generate a depth map of the surgical site of interest using the data representing the plurality of images.

摘要： A multispectral synchronized imaging system is provided. A multispectral light source of the system includes: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further includes a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

摘要： Methods and systems for outputting depth data during a medical procedure on a patient. Depth data is outputted, representing at least one of relative depth data and general depth data. Tracking information about the position and orientation of a medical instrument and depth information about variations in depth over a site of interest are used. Relative depth data represents the depth information relative to the position and orientation of the instrument. General depth data represents the depth information over the site of interest independently of the position and orientation of the instrument.
