Publication number: 20120002012Abstract: 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.Type: ApplicationFiled: August 13, 2010Publication date: January 5, 2012Applicant: Intuitive Surgical Operations, Inc.Inventors: Patrick O'Grady, Ian McDowall, Brian D.

Patent number: 8073528Abstract: 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.Type: GrantFiled: September 30, 2007Date of Patent: December 6, 2011Assignee: Intuitive Surgical Operations, Inc.Inventors: Wenyi Zhao, Christopher J.

Publication number: 20100166323Abstract: Systems, methods, and devices are used to match images. Points of interest from a first image are identified for matching to a second image. In response to the identified points of interest, regions and features can be identified and used to match the points of interest to a corresponding second image or second series of images. Regions can be used to match the points of interest when regions of the first image are matched to the second image with high confidence scores, for example above a threshold. Features of the first image can be matched to the second image, and these matched features may be used to match the points of interest to the second image, for example when the confidence scores for the regions are below the threshold value. Constraint can be used to evaluate the matched points of interest, for example by excluding bad points.Type: ApplicationFiled: May 13, 2009Publication date: July 1, 2010Applicant: Intuitive Surgical.

Publication number: 20100164950Abstract: 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.Type: ApplicationFiled: May 13, 2009Publication date: July 1, 2010Applicant: Intuitive Surgical, Inc.Inventors: Wenyi Zhao, Chenyu Wu, David Hirvonen, Christopher J.
