  • Patent number: 8108025
    Abstract: A system can be used to determine a position of a structure in physical space. The system can include a flexible member, such as a drape, cloth, sheet, etc. that can include one or more trackable devices associated therewith. The trackable devices can be incorporated into the weave of a woven cloth or the matrix of a polymer member. The trackable devices can be used within a tracking system to determine the location of the trackable devices.

  • Patent number: 8073530
    Abstract: This document discusses, among other things, fiducial marker devices, tools, and methods. One example illustrates a combined imagable fiducial locator and divot for receiving a positioning wand of an image-guided surgical (IGS) workstation. A further example is reflective such that it is locatable by a remote detector of an optical positioning system. A generally cylindrical (e.g., faceted cylindrical) columnar locator permits easy application of reflective tape. Other examples discusses a unitary fiducial marker with multiple divots and a swiveling and/or tilted fiducial marker divot, each of which allows manipulation of a positioning wand into a remote camera's field of view. Another example includes at least one reflector that can be aimed. A further example discusses an imagable fiducial marker carrier that is attachable to a single location on a patient's skull to reduce trauma.

  • Patent number: 8032204
    Abstract: This document discusses, among other things, fiducial marker devices, tools, and methods. One example illustrates a combined computed tomography (CT) imageable fiducial locator head, an integral bone screw, and an integral divot for receiving a positioning wand of an image-guided surgical (IGS) workstation. A further example includes a fluid/gel-absorbing coating or cover into which a magnetic resonance (MR) imageable fluid is introduced, thereby permitting both CT and MR imaging. Protective caps and collars may be used to protect the fiducial marker from mechanical impact and/or to guide the fiducial marker during affixation. A bull's-eye or other template is used to select a center of a substantially spherical fiducial marker head on an image, such as for use during patient registration.

  • Patent number: 8010177
    Abstract: A system to allow registration of a patient to image space is disclosed. The registration can be performed without touching a plurality of fiducial points on the patient or in the image data. The registration process can eliminate manual steps of image to patient registration and image to image registration.

  • Publication number: 20090012509
    Abstract: A system can be used to determine a position of a boney structure in physical space. The system can include a laser emitting device that can emit a laser beam that transmits through soft tissue and reflects off of a boney surface. The system can then determine the position of the reflection point and correlate the reflection point to image data acquired of a patient.

  • Patent number: 4204830
    Abstract: When a burner is supplied with preheated air, the temperature and density of the preheated air may vary during operation of the burner. When the density of the air supplied to a burner varies, it is necessary to vary the rate at which fuel is supplied to the burner in order to maintain a predetermined air-fuel ratio. To effect a variation in fuel flow with burner air density, the present invention utilizes a secondary air flow to simulate the heated flow of air to the burner. The flow rate of the secondary air varies in a manner which is a direct function of variations in the rate of flow of the heated burner air. Changes in the rate of flow of the secondary air are sensed at a predetermined reference temperature. The sensed variations in the secondary air flow are utilized to effect a corresponding change in the rate of fuel flow to maintain a constant air-fuel ratio.
