摘要： Devices and their uses for medical imaging in particular intra-operative imaging of tissue of a patient's body. The device comprises the illumination unit, the imaging unit, the processing unit and the display unit. The imaging unit captures fluorescent images (I_fluo) and live images (I_live) of the same scenery. In the processing unit, the fluorescent images (I_fluo) are processed by using the detected motion between the tissue and the imaging unit based on the detected motion. The filtered fluorescent images (I_filt) are non-linearly mapped into the live images (I_live) in order to improve the visibility of fluorophores in the tissue resulting in an overlay image (I_over) that comprises details of the live images (I_live) on the one hand and details of the fluorescent images (I_fluo) on the other hand.

摘要： An endoscopic system includes an endoscopic imager configured to capture image frames of a target site within a living body and a processor configured to apply a spatial transform to a preliminary set of image frames, the spatial transform converting the image frames into cylindrical coordinates; calculate a map image from the spatially transformed image frames, each pixel position in the map image being defined with a vector of fixed dimension; align a current image frame with the map image and apply the spatial transform to the current image frame; fuse the spatially transformed current image frame to the map image to generate a fused image; and apply an inverse spatial transform to the fused image to generate an enhanced current image frame having a greater spatial resolution than the current image frame. The system also includes a display displaying the enhanced current image frame.

摘要： System and method for imaging a target site with a housing assembly having a head unit configured to be at least partially directed towards the target site. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second of volumetric data of the target site, respectively. A controller is configured to register the first set of volumetric data with the second set of volumetric data to create a third set of registered volumetric data. The third set of registered volumetric data and second set of volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a composite shared view of the target.

摘要： Techniques are disclosed for adding time data to scan lines of an image frame. In some examples, an image sensor may perform a rolling shutter image capture to produce the scan lines. Data captured by another sensor may be associated with at least a portion of a scan line based at least in part on the time data added to the scan line in some examples. Furthermore, techniques are disclosed for synchronizing data capture by multiple sensors. For example, a rolling shutter image capture performed by an image sensor may be synchronized with a data capture performed by another sensor.
