摘要:
A system is provided to align a surgical guide instrument over a burr hole in a patient's body. Adjustments of a surgical instrument can be made in x, y, z, and angular directions using the system. An instrument guide unit can include an instrument guide for guiding a surgical instrument into the body of a patient and a base unit operative to be secured to the body near an area in which surgery is to occur. The base unit is coupled to the instrument guide. An adjustment mechanism, coupled to the base unit and the instrument guide, is operative to adjust the instrument guide in lateral directions with respect the surface of the area.

The present disclosure is directed to a planning and navigation method. The planning and method includes obtaining and rendering a plurality of images. The plurality of images are segmented to demarcate a target area. A treatment plan is determined based on the target area. The navigation method includes obtaining an ultrasound image of a scan plane including the target and obtaining a fiducial image of a fiducial pattern disposed on an ultrasound device. The obtained fiducial image is corrected and a correspondence between the fiducial image and a model image is found. A position of the surgical device is transformed to model coordinates. Then the ultrasound image and a virtual image of the surgical device is displayed to allow a surgeon to navigate the surgical device to the target using the displayed ultrasound image and the virtual image. The target is treated based on the treatment plan.
摘要:
Various technologies and techniques are disclosed for generating project milestones. A method for programmatically determining a status of a particular task is described. Project management data for a particular task is retrieved from a data store. Milestone indicators are retrieved from a key word data store. An analysis is performed of the project-related files to determine an actual status of the particular task, using the milestone indicators and project management data as part of the analysis. When the analysis reveals that the project-related files reflect a different status for the project than the project management data reflects, one or more notifications are raised.

The present disclosure is directed to an ablation planning and navigation system. The planning system includes a memory configured to store a plurality of images and a controller configured to render the plurality of images in three dimensions, automatically segment the plurality of images to demarcate a target area, and automatically determine a treatment plan based on the target area. The navigation system includes an ultrasound device having a fiducial pattern that obtains an ultrasound image, an ablation needle having a image capture device that captures an image of the fiducial pattern, and a controller that receives the ultrasound image and the fiducial image. The controller determines a position of the ablation needle based on the fiducial image. The planning and navigation system also includes a controller that receives data from the planning system and the navigation system and a display configured to display the received information.

The present disclosure is directed to fiducial tracking system. The fiducial tracking system includes a first device having a fiducial pattern disposed thereon and a second device having an image capture device disposed thereon. The image capturing device is configured to obtain a fiducial image of the fiducial pattern. A controller is also provided that is configured to receive the fiducial image, correct the fiducial image for lens distortion, find correspondence between the fiducial image and a model image, estimate a camera pose, and transform a position of the second device to model coordinates.

A nozzle inhibitor is positioned in a filler neck closure assembly between a pivotable outer door and a pivotable inner door to prevent a user from pumping unleaded fuel into a diesel fuel tank. The nozzle inhibitor blocks full insertion of a small-diameter unleaded fuel nozzle into the filler neck closure assembly yet allows full insertion of a large-diameter diesel fuel nozzle into the filler neck closure assembly.

The present disclosure is directed to a surgical navigation system. The navigation system includes an ultrasound device configured to obtain an ultrasound image in a scan plane The ultrasound device has a fiducial pattern disposed thereon. A surgical device having an image capture device configured to capture a fiducial image of the fiducial pattern is also provided. The system also includes a controller configured to receive the ultrasound image and the fiducial image, wherein the controller determines a position of the surgical device in relation to the scan plane based on the fiducial image. A display is configured to display the ultrasound image and a virtual image of the surgical device based on the position of the surgical device in relation to the scan plane.
