An endoscope with a stereoscopic optical channel is held and positioned by a robotic surgical system. A first capture unit captures: a visible first color component of a visible left image combined with a fluorescence left image from first light from one channel in the endoscope; a visible second color component of the visible left image from the first light; and a visible third color component of the visible left image from the first light. A second capture unit captures: a visible first color component of a visible right image combined with a fluorescence right image from second light from the other channel in the endoscope; a visible second color component of the visible right image from the second light; and a visible third color component of the visible right image from the second light. An augmented stereoscopic outputs a real-time stereoscopic image including a three-dimensional presentation including the visible left and right images and the fluorescence left and right images.

A projection-based x-ray imaging system combines projection magnification and optical magnification in order to ease constraints on source spot size, while improving imaging system footprint and efficiency. The system enables tomographic imaging of the sample especially in a proximity mode where the same is held in close proximity to the scintillator. In this case, a sample holder is provided that can rotate the sample. Further, a z-axis motion stage is also provided that is used to control distance between the sample and the scintillator.

The present disclosure relates to calibration assemblies and methods for use with an imaging system, such as an endoscopic imaging system. A calibration assembly includes: an interface for constraining engagement with an endoscopic imaging system; a target coupled with the interface so as to be within the field of view of the imaging system, the target including multiple of markers having calibration features that include identification features; and a processor configured to identify from first and second images obtained at first and second relative spatial arrangements between the imaging system and the target, respectively, at least some of the markers from the identification features, and using the identified markers and calibration feature positions within the images to generate calibration data.

A local contrast enhancement method transforms a first plurality of color components of a first visual color image into a modified brightness component by using a first transformation. The first plurality of color components are in a first color space. The modified brightness component is a brightness component of a second color space. The second color space also includes a plurality of chromatic components. The method transforms all the color components of the first color space into the chromatic components of the second color space. The method then transforms the modified brightness component and the chromatic components of the second color space into a plurality of new color components, in the first color space, of a second visual color image. The method transmits the plurality of new color components to a device such as a display device. The second visual color image has enhanced contrast in comparison to the first visual color image.

A digital dual-band detector functions as an imaging platform capable of extracting hard and soft tissue images, for example. The detector has a first detector system comprising a first scintillator for converting x-rays from a sample to an first optical signal, and a first detector for detecting the first optical signal in combination with a second detector system comprising a second scintillator for converting x-rays from the sample and passing through the first scintillator to a second optical signal, and a second detector for detecting the second optical signal. The detector can facilitate the implementation and deployment of recent developments and can permit low cost practical deployment in clinical applications as well as biomedical research applications where significant improvement in spatial resolution and image contrast is required.

In one embodiment of the invention, an apparatus is disclosed including an image sensor, a color filter array, and an image processor. The image sensor has an active area with a matrix of camera pixels. The color filter array is in optical alignment over the matrix of the camera pixels. The color filter array assigns alternating single colors to each camera pixel. The image processor receives the camera pixels and includes a correlation detector to detect spatial correlation of color information between pairs of colors in the pixel data captured by the camera pixels. The correlation detector further controls demosaicing of the camera pixels into full color pixels with improved resolution. The apparatus may further include demosaicing logic to demosaic the camera pixels into the full color pixels with improved resolution in response to the spatial correlation of the color information between pairs of colors.
