Patent number: 9055874Abstract: A motion tracker including a head band and laser devices that direct laser beams having non-concentric axes to a charge coupled device is used to determine movement of a patient during a CT scan. When the patient is motionless, the laser devices each direct a laser beam along a line, and the laser beams contact the charge coupled device at a contact location. If the patient moves, the laser devices, and therefore the contact locations, move. The charge coupled device detects the movement of the contact locations to determine the movement of the patient. A computer adjusts the x-ray image taken at the time of the movement to accommodate for this movement.Type: GrantFiled: January 28, 2008Date of Patent: June 16, 2015Assignee: Xoran Technologies, Inc.Inventors: William C. Van Kampen, Predrag Sukovic

Patent number: 8303181Abstract: An imaging system includes a source and a detector that can be quickly and easily moved out of the way after scanning. During scanning, the actual paths that the source and detector travel are tracked, such as by an associated surgical navigation system tracking system. The actual locations of the source and detector during each x-ray image are used in the image reconstruction algorithm. Since the actual locations are used in the algorithm, the locations do not have to be as precisely controlled. In one embodiment, the source and detector are mounted proximate outer ends of first and second c-arm sections. The first and second c-arm sections are extendable to form a complete c-arm and retractable to a collapsed position when not in use. In the disclosed embodiment, the c-arm sections are mounted to a base or carriage under the patient support surface (such as the surgical table).Type: GrantFiled: August 9, 2004Date of Patent: November 6, 2012Assignee: Xoran Technologies, Inc.Inventors: Predrag Sukovic, Neal Clinthorne, Nathaniel Bair

Patent number: 7905660Abstract: A CT scanner includes a pair of shields to protect an operator from x-rays from the CT scanner. The CT scanner has a gantry that provides structural support and housing for the components including an x-ray source and a detector arranged on the gantry to face one another. Lead shields are located on opposing sides of the x-ray source and extend between the x-ray source and the detector. The CT scanner further includes a computer located on an opposing side of the gantry from the x-ray source and the detector. The lead shields rotate with the gantry and prevent the x-ray from reaching the operator while the CT scanner is in operation.Type: GrantFiled: September 1, 2009Date of Patent: March 15, 2011Assignee: Xoran Technologies, Inc.Inventors: Predrag Sukovic, Neal Clinthorne, Miodrag Rakic, James A.

Patent number: 7460637Abstract: A high spatial resolution X-ray computed tomography (CT) system is provided. The system includes a support structure including a gantry mounted to rotate about a vertical axis of rotation. The system further includes a first assembly including an X-ray source mounted on the gantry to rotate therewith for generating a cone X-ray beam and a second assembly including a planar X-ray detector mounted on the gantry to rotate therewith. The detector is spaced from the source on the gantry for enabling a human or other animal body part to be interposed therebetween so as to be scanned by the X-ray beam to obtain a complete CT scan and generating output data representative thereof. The output data is a two-dimensional electronic representation of an area of the detector on which an X-ray beam impinges. A data processor processes the output data to obtain an image of the body part.Type: GrantFiled: October 27, 2005Date of Patent: December 2, 2008Assignee: The Regents of The University of MichiganInventors: Neal H. Clinthorne, Predrag Sukovic

Publication number: 20080267343Abstract: A CT scanner system provides projection-like images of a patient volume. After a CT scan is obtained and a three-dimensional model of the patient is created, any synthetic view can be generated by choosing any array of projection lines, e.g. between a point and a surface (a flat plane, curved plane, spherical, etc) or between two surfaces (parallel or not) and summing across the projection lines. The synthetic projections can mimic certain traditional views, such as a ceph scan, Water's view, Caldwell's projection, etc or can provide a new view that is impossible or impractical with traditional x-ray equipment, such as a perfect parallel projection, or a projection that does not pass all the way through the patient.Type: ApplicationFiled: June 5, 2008Publication date: October 30, 2008Inventors: Predrag Sukovic, Neal Clinthorne, Joseph Webster Stayman, Miodrag Rakic

Publication number: 20080260095Abstract: A CT scanner includes a gantry including a first arm and a second arm. The first arm houses an x-ray source that generate x-rays, and the second arm houses a complementary flat-panel detector. During a pre-operative CT scan, the CT scanner is positioned at a scanning position near the patient. An alignment feature ensures that the CT scanner is repeatably positionable in the scanning position. After the pre-operative scan is complete, the CT scanner is moved to a remote position. If an updated CT scan is needed during the surgical procedure, the CT scanner is moved from the remote position to the scanning position. The alignment feature ensures that the CT scanner is properly positioned in the scanning position.Type: ApplicationFiled: April 16, 2008Publication date: October 23, 2008Inventors: Predrag Sukovic, William C. Van Kampen, Joseph Webster Stayman, Miodrag Rakic, James A. Bertolina, James F. O'Connell, David Phillipe Sarment, Neal Clinthorne

Publication number: 20080205584Abstract: A CT scanner according to the present invention is particularly adapted for scanning the extremities of a patient. The CT scanner includes an x-ray source and x-ray detector mounted for rotation and translation along an axis parallel to a table for supporting the patient's extremity. The source and detector are mounted opposite one another on an inner circumference of an inner ring. The inner ring is rotatable about the axis within an outer ring mounted on at least one carriage. The carriage is movable parallel to the axis. During scanning, the inner ring rotates within the outer ring while the rings and carriage move along the axis, thereby producing a helical scan of the extremity.Type: ApplicationFiled: February 25, 2008Publication date: August 28, 2008Inventors: PREDRAG SUKOVIC, Neal Clinthorne, Nathaniel Bair

Publication number: 20080181356Abstract: A camera mounted to a CT scanner can be used to provide technical assistance relating to the CT scanner. The camera captures an image of an operator of the CT scanner, and the image is provided to a technician at an off-site technical support center. The camera can take external images of a patient while the CT scanner captures x-ray images of the patient, and a computer registers the images relative to each other. The camera can be used when the CT scanner is operating in a fluoroscopy mode, for motion tracking or motion correction of a three dimensional CT image, or for soft-tissue simulation of an area of the patient that is to undergo surgery.Type: ApplicationFiled: January 28, 2008Publication date: July 31, 2008Inventors: Predrag Sukovic, Neal Clinthorne, Miodrag Rakic, Joseph Webster Stayman, David Phillipe Sarment, Matt Jacobson

Patent number: 7394888Abstract: A CT scanning system provides the ability to scan a patient's lower extremities while the patent is upright, i.e. either standing on the foot, or at least putting some load on the foot, or with the ankle at a given angle. The CT scanning system provides a generally horizontal upper support surface on which the patient's foot is supported. A gantry supporting an x-ray source and x-ray detector are rotated about a z-axis through the support surface. With the CT scanning system, the patient's lower extremities can be scanned while under load.Type: GrantFiled: May 2, 2006Date of Patent: July 1, 2008Assignee: Xoran Technologies, Inc.Inventors: Predrag Sukovic, Neal Clinthorne, James A.

Publication number: 20080031408Abstract: A CT scanner takes a three-dimensional CT image, and a right sinus cavity and a left sinus cavity of a patient are identified in the CT image. The sinus cavities can be manually or automatically identified. When the sinus cavities are clear, the sinus cavities appear black in the CT image. When fluid or static polyps fill the sinus cavities, the sinus cavities appear gray in the CT image. A computer evaluates the CT image to quantify the amount of fluid or static polyps in the sinus cavities.Type: ApplicationFiled: July 26, 2007Publication date: February 7, 2008Inventors: Predrag Sukovic, Neal Clinthorne, Joseph Webster Stayman, Miodrag Rakic
