  • Patent number: 8432436
    Abstract: An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system.

  • Publication number: 20130041226
    Abstract: In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

  • Publication number: 20130021457
    Abstract: The multi-person stereo display system permits several independent viewers to see different stereo images on a single projection surface. This is accomplished through the innovative use of video multiplexing, software, control electronics, and special viewing glasses. The system is particularly useful in situations where the viewers see computer generated images from their own independent perspectives.

  • Patent number: 8167793
    Abstract: An endoscope with a stereoscopic optical channel is again held and positioned by a robotic surgical system. A capture unit captures (1) at a first time, a first image from light from the channel; and (2) at a second time different from the first time, a second image from the light. Only one of the first image and the second image includes a combination of a fluorescence image and a visible image. The other of the first image and the second image is a visible image. An intelligent image processing system generates an artificial fluorescence image using the captured fluorescence image. An augmented stereoscopic display system outputs an augmented stereoscopic image of at least a portion of the tissue comprising the artificial fluorescence image.

  • Patent number: 8169468
    Abstract: A robotic surgical system positions and holds an endoscope. A visible imaging system is coupled to the endoscope. The visible imaging system captures a visible image of tissue. An alternate imaging system is also coupled to the endoscope. The alternate imaging system captures a fluorescence image of at least a portion of the tissue. A stereoscopic video display system is coupled to the visible imaging system and to the alternate imaging system. The stereoscopic video display system outputs a real-time stereoscopic image comprising a three-dimensional presentation of a blend of a fluorescence image associated with the captured fluorescence image, and the visible image.

  • Publication number: 20120002956
    Abstract: In a minimally invasive surgical system, a camera includes a prismatic element having a lens within the prismatic element. The lens corrects the resulting image focus for the non-visible light to make it substantially the same as the focus for the visible light. Alternatively, the lens corrects the resulting image focus for the visible light to make it substantially the same as the focus for the non-visible light.

  • Publication number: 20120002012
    Abstract: A minimally invasive surgical includes a scene anti-bloom process that allows switching between imaging modes on a stereoscopic display without causing a surgeon to look-away or being momentarily distracted by sudden changes in overall scene luminance. The process receives a switch from a first imaging mode to a second imaging mode. An overall scene luminance of a scene in the first imaging mode is less than an overall scene luminance of a scene in the second imaging mode. The process delays the switch to the second imaging mode until after an illumination output level of a visible illumination source has changed to a higher output level, and then switches to the second imaging mode.

  • Publication number: 20120004508
    Abstract: In a minimally invasive surgical system, an illuminator includes a visible color component illumination source and a hardware non-visible fluorescence emission illumination source. Thus, the illuminator outputs target image illumination light in a first spectrum where the first spectrum includes at least a portion of the visible spectrum. The illuminator also outputs target image illumination light in a second spectrum, where the second spectrum includes non-visible light with a wavelength the same as a wavelength in an emission from a fluorophore.

  • Publication number: 20120004557
    Abstract: A surgical site is simultaneously illuminated by less than all the visible color components that make up visible white light, and a fluorescence excitation illumination component by an illuminator in a minimally invasive surgical system. An image capture system acquires an image for each of the visible color components illuminating the surgical site and a fluorescence image, which is excited by the fluorescence excitation component from the illuminator. The minimally invasive surgical system uses the acquired images to generate a background black and white image of the surgical site. The acquired fluorescence image is superimposed on the background black and white image, and is highlighted in a selected color, e.g., green. The background black and white image with the superimposed highlighted fluorescence image is displayed for a user of the system. The highlighted fluorescence image identifies tissue of clinical interest.

  • Publication number: 20110082369
    Abstract: In one embodiment of the invention, an apparatus includes a display device. The display device displays a desaturated image of tissue captured in the visible electro-magnetic (EM) spectrum from a body cavity; and a first color enhanced image combined with the desaturated image. The first color enhanced image represents the first data captured from the body cavity outside the visible electromagnetic spectrum. The relative brightness between the desaturated image and the first color enhanced image is set to emphasize the first data over the tissue captured in the visible electromagnetic spectrum to provide improved information content.
