摘要： Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.

摘要： The application as disclosed herein describes systems and methods for performing patient registration using a surgical navigation system. This application attempts to provide for improvements upon existing systems through the addition of refinement steps used to increase the accuracy of registration and streamline said process. In some cases the improvements generally involve the manipulation of spatial data in an iterative manner.

摘要： A method and system to identify function in areas of a cerebral cortex using optical coherence tomography to scan an area and compare the scan to a cytoarchitectural database of classified images. A matched image has an associated likely function. Using a navigation system, the location of the cerebral cortex scanned is determined and is associated with the likely function corresponding to the matched image. A registration module may generate an image, possibly including pre-operative scan data, of the cerebral cortex with likely functions indicated for the scanned locations.

摘要： A phantom to determine navigational error in a surgical navigation system that tracks the location of an elongate tool having a tip and a shaft based on a plurality of fiducials attached to the elongate tool. The phantom includes a base portion that models a lower portion of a mammalian head and having a top surface with a plurality of touch points, each of the touch points being a respective indentation, and a frame detachably securable to the base portion and having an upper portion spaced apart from the top surface, the upper portion having defined therein a plurality of apertures. A tip of the elongate tool is to be inserted through said one of the apertures and in one of the touch points, and the surgical navigation system determines positional and angular error.

摘要： A medical navigation system for displaying a three dimensional (3D) surface video of a target is provided. The medical navigation system comprises a 3D imaging device, a camera, a display, and a controller electrically coupled to the 3D imaging device, the camera, and the display. The controller has a processor coupled to a memory. The controller is configured to perform calibration of input devices; acquire 3D depth data of the target from a signal generated by the 3D imaging device; construct a 3D surface contour of the target based on the 3D depth data; acquire a video stream of the target from a signal generated by the camera; generate a 3D surface video based on the 3D surface contour and the video stream; and display the 3D surface video on the display.

摘要： A method, system and apparatus for surface rendering using medical imaging data is provided. A display device is controlled to render a first model of imaging data showing depth positions corresponding to a given surface threshold value, and further controlled to replace the first model with a second model of the imaging data showing respective depth positions corresponding to the given surface threshold value, the second model being faster to compute than the first model. The given surface threshold value is changed to an updated surface threshold value, for example using a slider input. The display device updates rendering of the second model to show updated respective depth positions corresponding to the updated surface threshold value. When an acceptance is received, the display device is controlled to replace the second model with the first model showing updated depth positions corresponding to the updated surface threshold value.
