  • 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.

  • Patent number: 8073528
    Abstract: In one embodiment of the invention, a tool tracking system is disclosed including a computer usable medium having computer readable program code to receive images of video frames from at least one camera and to perform image matching of a robotic instrument to determine video pose information of the robotic instrument within the images. The tool tracking system further includes computer readable program code to provide a state-space model of a sequence of states of corrected kinematics information for accurate pose information of the robotic instrument. The state-space model receives raw kinematics information of mechanical pose information and adaptively fuses the mechanical pose information and the video pose information together to generate the sequence of states of the corrected kinematics information for the robotic instrument. Additionally disclosed are methods for image guided surgery.

  • Publication number: 20100317965
    Abstract: Robotic and/or measurement devices, systems, and methods for telesurgical and other applications employ input devices operatively coupled to tools so as to allow a system user to manipulate tissues and other structures being measured. The system may make use of three dimensional position information from stereoscopic images. Two or more discrete points can be designated in three dimensions so as to provide a cumulative length along a straight or curving structure, an area measurement, a volume measurement, or the like. The discrete points may be identified by a single surgical tool or by distances separating two or more surgical tools, with the user optionally measuring a structure longer than a field of view of the stereoscopic image capture device by walking a pair of tools “hand-over-hand” along the structure.

  • Publication number: 20100164950
    Abstract: An apparatus is configured to show telestration in 3-D to a surgeon in real time. A proctor is shown one side of a stereo image pair, such that the proctor can draw a telestration line on the one side with an input device. Points of interest are identified for matching to the other side of the stereo image pair. In response to the identified points of interest, regions and features are identified and used to match the points of interest to the other side. Regions can be used to match the points of interest. Features of the first image can be matched to the second image and used to match the points of interest to the second image, for example when the confidence scores for the regions are below a threshold value. Constraints can be used to evaluate the matched points of interest, for example by excluding bad points.

  • Publication number: 20090270678
    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: 7561141
    Abstract: A haptic feedback control device, such as a handheld remote control or handheld game controller, for controlling a graphical object within a graphical display and for outputting forces to a user. A housing includes a button, wherein the user engages the button with a finger. The button is depressible along a degree of freedom by the user. An actuator applies forces to the user through the button along the degree of freedom. A sensor detects displacement of the button along the degree of freedom when the button is depressed by the user. A process, local to the device, controls the actuator to generate the forces upon the button in the degree of freedom to provide a tactile sensation to the user contacting the button.
