In at least one embodiment, the device includes at least one device for mechanical, electrical, magnetic, thermal, optical and/or chemical stimulation of the trigeminal nerve. Furthermore, at least one embodiment relates to an apparatus including at least one such device and a unit for registering the heart rate of the patient, which unit interacts with the device. Furthermore, at least one embodiment moreover relates to a method for reducing the heart rate of a patient in order to record image information from the heart of the patient, in which method the trigeminal nerve of the patient is stimulated by at least one such device in order to lower the heart rate of the patient.Type: ApplicationFiled: March 1, 2011Publication date: September 8, 2011Applicant: Siemens AktiengesellschaftInventors: Eckhard Hempel, Stefan Popescu, Nicolae Rusca

Publication number: 20110218430Abstract: The invention comprises a patient positioning and/or repositioning system, such as a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle radiation therapy. Patient positioning constraints optionally include one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are preferably movable and/or under computer control for rapid positioning, repositioning, and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the charged particle beam path to accurately and precisely target the tumor, and/or in system verification and validation.Type: ApplicationFiled: May 21, 2009Publication date: September 8, 2011Inventor: Vladimir Yegorovich Balakin

Patent number: 8010181Abstract: The present invention concerns a system for utilizing radio frequency signals to dynamically determine the location of a medical device throughout a procedure and to improve navigation of the medical device. For these purposes, a plurality of RF receivers are mounted at operative locations in the operating room and operate on the same clock signal. The system also utilizes a diagnostic medical image such as an MRI, and overlays the position feedback signal on the image. This allows, for example, a surgeon to pick a desired spot on the diagnostic image, and then cause a robotic arm driven device to be moved to that particular spot inside the human body.Type: GrantFiled: February 16, 2007Date of Patent: August 30, 2011Assignee: Catholic Healthcare WestInventors: David W. Smith, Regina DeSanctis-Smith, Alan M. Pitt, Nicholas Theodore, Neil Crawford

Patent number: 8010184Abstract: A region of interest is automatically evaluated. The automatic evaluation is based on assessments of one or more characteristics. The one or more characteristics of the region of interest are assessed in a plurality of image data sets acquired by a respective plurality of imaging modalities. In some embodiments, the evaluation is based on assessments of one or more characteristics for each region of interest derived from a combination of structural and functional image data. In one embodiment, the set of structural image data is a set of CT image data and the set of functional image data is a set of PET image data. The one or more lesions may be detected in the structural and/or functional image data by automated routines or by a visual inspection by a clinician or other reviewer.Type: GrantFiled: November 30, 2005Date of Patent: August 30, 2011Assignee: General Electric CompanyInventors: Ricardo Avila, Floribertus Heukensfeldt Jansen, Dinko Gonzalez Trotter, James Miller, Ravindra Manjeshwar, Thomas Sebastian

Patent number: 8010180Abstract: A surgical apparatus includes a surgical device, configured to be manipulated by a user to perform a procedure on a patient, and a computer system. The computer system is programmed to implement control parameters for controlling the surgical device to provide at least one of haptic guidance to the user and a limit on user manipulation of the surgical device, based on a relationship between an anatomy of the patient and at least one of a position, an orientation, a velocity, and an acceleration of a portion of the surgical device, and to adjust the control parameters in response to movement of the anatomy during the procedure.Type: GrantFiled: February 21, 2006Date of Patent: August 30, 2011Assignee: MAKO Surgical Corp.Inventors: Arthur Quaid, Hyosig Kang, Dennis Moses, Rony Abovitz, Scott Illsley

Patent number: 8000766Abstract: Methods of diagnosing and preventing bone loss and/or enhancing bone formation are disclosed. The invention additionally provides methods of diagnosing a predisposition to bone loss. The methods mathematically combine the information provided by imaging tests with the information provided by biomarkers to provide an index value. The index value is used for diagnosis of bone diseases, and to assess the progress of treatment of bone diseases.Type: GrantFiled: May 28, 2002Date of Patent: August 16, 2011Assignee: ImaTx, Inc.Inventors: Philipp Lang, Claude Arnaud, Daniel Steines
