Publication number: 20130190623Abstract: A Histotripsy therapy transducer is provided that can include any number of features. In some embodiments, the transducer is sized and configured to direct Histotripsy energy through the perineal window into the prostate. The Histotripsy therapy transducer can include a notch or opening near the periphery of the transducer to accommodate a transrectal imaging probe. The notch or opening in the therapy transducer allows for movement of the therapy with respect to the imaging probe without contact or interference from the imaging probe. In some embodiments, the transducer can be “heart-shaped” or round. Methods of use are also described.Type: ApplicationFiled: January 7, 2013Publication date: July 25, 2013Inventors: James A.

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: 7556428Abstract: A surgical navigation system includes a CT scanner that takes a plurality of x-ray images of a patient. A patient tracker including locators is attached to the patient, and a registration appendage is removably secured to the patient tracker in a known position and orientation. The registration appendage includes radio-opaque markers arranged in a predetermined geometric pattern. The registration appendage is viewable in a CT scan in situations where the locators of the patient tracker are outside of a field of view of the CT scanner.Type: GrantFiled: April 16, 2007Date of Patent: July 7, 2009Assignee: Xoran Technologies, Inc.Inventors: Predrag Sukovic, Miodrag Rakic, James A.

Publication number: 20080312528Abstract: A scanner takes an initial image of a patient, and a known structure in the initial image is identified. Based on the initial image, a location for injection of a chemical with a medical instrument can be determined. During a medical procedure, the scanner operates in a fluoroscopy mode, and real-time images of the patient are displayed. The medical instrument includes two markers having a fixed and known relationship and orientation relative to each other and a tip of the medical instrument Movement of the tip is monitored as it is inserted into the patient, and the location of the tip relative to the injection location is tracked based on the detected relationship of the markers of the medical instrument and the known structure. When the computer determines that the tip is at the injection location, the computer provides an alert to inject the chemical.Type: ApplicationFiled: June 16, 2008Publication date: December 18, 2008Inventor: James A. Bertolina

Publication number: 20080285722Abstract: A CT scanner includes a gantry including a first arm and a second arm. One of the first arm and the second arm houses an x-ray source that generates x-rays, and the other of the first arm and the second arm houses a complementary flat-panel x-ray detector. The first arm is rotatable about an axis relative to the second arm. During a CT scan, the first arm is in a CT scanning position. When the CT scanner is no longer needed, the first arm is rotated relative to the second arm about the axis, allowing the first arm to move to a collapsed position. If another CT scan is required during a surgical procedure, the first arm is rotated about the axis from the collapsed position to the CT scanning position.Type: ApplicationFiled: April 16, 2008Publication date: November 20, 2008Inventor: James A. Bertolina

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

Patent number: 7422368Abstract: A CT scanner includes a base, two fixed portions extending transversely from the base, and a rocking beam pivotally attached to the base about an axis. The CT scanner includes four wheels that allow the CT scanner to move over a floor. A wheel is attached to each fixed portion, and a wheel is attached to each end of the rocking beam. If the CT scanner is positioned on a floor with an unlevel portion, the rocking beam rotates about the axis. One wheel attached to the rocking beam raises in a generally vertical direction, and the other beam attached to the rocking beam lowers in a generally vertical direction so all four wheels contact the floor, stabilizing the CT scanner and preventing rocking.Type: GrantFiled: October 12, 2006Date of Patent: September 9, 2008Assignee: Xoran Technologies, Inc.Inventors: Joseph Webster Stayman, David C. Brown, Wai Ngai Chin, James F. O'Connell, James A. Bertolina, Dejen Teofilovic

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: 20070248206Abstract: A surgeon selects a volume of interest by placing an untracked “marker” in a patient near an area where an update is desired. During surgery, when an updated CT scan is requested, the CT scanner performs a scan of the patient using a full field of view to take a series of two-dimensional initial images of the patient from a plurality of angularly spaced positions about the patient. The position of the untracked marker is determined by the CT scanner in or more of the initial images. The volume of interest is defined as the position of the untracked marker, plus some margin. The CT scanner then collimates the x-ray source to scan only the volume of interest. The CT scanner then completes the update scan of the volume of interest and updates a previous CT scan(s) to create a fully updated CT image, reducing x-ray exposure of the patient.Type: ApplicationFiled: April 19, 2007Publication date: October 25, 2007Inventors: Predrag Sukovic, William Van Kampen, Joseph Stayman, Miodrag Rakic, James Bertolina, David Sarment, James O'Connell
