  • Publication number: 20240058076
    Abstract: A high-speed optical tracking with compression and CMOS windowing for tracking applications that require high-speed and/or low latency when delivering pose (orientation and position) data. The high-speed optical tracking with compression and CMOS windowing generally includes an optical tracking system (10) that sense fiducial (22) and by extension markers (20). The markers can either be integrated on tools (20) handled by an operator (e.g. surgeon) (50) or fixed on the subject to track (e.g. patient) (40). The low-level processing (101, 107, 140) is realized within the tracking system to reduce the overall data to be transferred and considerably reduce the processing efforts. Pose data (127) are finally computed and transferred to a PC/monitor (30,31) or to tablet (60) to be used by an end-user application (130).

  • Patent number: 11896320
    Abstract: A system is disclosed that includes an optical tracking device and a surgical computing device. The optical tracking device includes a structured light module and an optical module that includes an image sensor and is spaced from the structured light module at a known distance. The surgical computing device includes a display device, a non-transitory computer readable medium including instructions, and processor(s) configured to execute the instructions to generate a depth map from a first image captured by the image sensor during projection of a pattern into a surgical environment by the structured light module. The pattern is projected in a near-infrared (NIR) spectrum. The processor(s) are further configured to execute the stored instructions to reconstruct a 3D surface of anatomical structure(s) based on the generated depth map. Additionally, the processor(s) are configured to execute the stored instructions to output the reconstructed 3D surface to the display device.

  • Publication number: 20230408540
    Abstract: A method is described of operating a pipetting system (10) that has a worktable (12), at least one manipulator arm (18), and first and second Z-rods (20?,20?) arranged on the at least one manipulator arm (18). The method involves receiving by the second Z-rod (20?) a tool (24) via an adapter attached to the second Z-rod (20?), wherein the tool (24) has a central axis and a working area, the working area being defined by a circle which center is located on the central axis of the tool (24) and which radius being a distance between the central axis and a largest extension of an outline of the tool (24) in a projection.

The high-speed optical tracking with compression and CMOS windowing generally includes an optical tracking system (10) that sense fiducial (22) and by extension markers (20). The markers can either be integrated on tools (20) handled by an operator (e.g. surgeon) (50) or fixed on the subject to track (e.g. patient) (40). The low-level processing (101, 107, 140) is realized within the tracking system to reduce the overall data to be transferred and considerably reduce the processing efforts. Pose data (127) are finally computed and transferred to a PC/monitor (30,31) or to tablet (60) to be used by an end-user application (130).

  • Patent number: 11103313
    Abstract: The present invention relates to a redundant reciprocal tracking system composed of at least two trackers 10. A first tracker is able to sense partial or full pose data (orientation and position) of a second tracker in a first reference frame and the second tracker is able to sense partial or full pose data of the first tracker in a second reference frame. Pose data of first and second trackers are further transferred to a central processor 30, which is able to compute the transformation between first and second reference frame. Data generated by the trackers are such designed that they define an over-determined mathematical system (e.g. more than 6 degrees of freedom in a 3D setup). The over-determined information can be used to qualify and/or improve the transformation of the reference frame. In an embodiment of the invention, the tracking system is an optical one and the over-determined information defines an error metric used to check the validity of the transformation.
