The probe, e.g., an ultrasound transducer can be rotated within the frame such that the probe scans at least either of two perpendicular directions within the frame.Type: GrantFiled: October 31, 2002Date of Patent: December 12, 2006Assignee: Manoa Medical, Inc.Inventor: Roberta Lee

Patent number: 7117027Abstract: A system and method for preparing a virtual three-dimensional representation of a first portion of a bone. The method may comprise obtaining, from a first orientation with respect to the first portion of the bone, first image data of the first portion of the bone and obtaining, from a second, different orientation with respect to the first portion of the bone, second image data of the first portion of the bone. A three-dimensional (3D) virtual representation of the first portion of the bone may be generated. The 3D virtual representation of the first portion of the bone may be displayed. The displayed 3D virtual representation may have an orientation, determined using at least the difference between the first and second orientations from which the first and second image data were obtained.Type: GrantFiled: July 30, 2003Date of Patent: October 3, 2006Assignee: Synthes (USA)Inventors: Guoyan Zheng, Lutz-Peter Nolte

Patent number: 7110805Abstract: MRI echo data is acquired by performing selective-excitation on regions composed of multi-slices of an object, while the object is moved continuously. The positions of the multi-slices are moved within a predetermined imaging range fixedly determined by an MRI system, according to object movement. This allows positions of the multi-slices to be changed in compliance with the moved object, so that the multi-slices positionally track with the object within the imaging range. Accordingly, a multi-slice imaging technique can be provided, which is executable during even continuous movement of the object.Type: GrantFiled: September 21, 2001Date of Patent: September 19, 2006Assignee: Kabushiki Kaisha ToshibaInventor: Yoshio Machida

Patent number: 7110806Abstract: The present invention is a technique and apparatus for acquiring anatomic information used in diagnosing and characterizing abdominal aortic aneurismal disease and the like. This technique provides anatomic information, in the form of images, using a combination of a plurality of magnetic resonance angiography sequences, including a spin-echo and four contrast enhanced (e.g., gadolinium) magnetic resonance angiography sequences. The anatomic images may be used in, for example, pre-operative, operative and post-operative evaluation of aortic pathology, including aneurysms, atherosclerosis, and occlusive disease of branch vessels such as the renal arteries. The gadolinium-enhanced magnetic resonance angiography provides sufficient anatomic detail to detect aneurysms and all relevant major branch vessel abnormalities seen at angiography operation.Type: GrantFiled: August 26, 2003Date of Patent: September 19, 2006Inventor: Martin R. Prince

Patent number: 7069068Abstract: Haemodynamic indices of an organ or a part of tissue are determined from a time series of tomographic data obtained by means of Magnetic Resonance Imaging. Maps of indices are produced, being significant of the dynamics of the capillary tissue flow acquired during rapid bolus injection of a tracer that stays mainly intravascular. The method may be used for evaluating the efficacy of a drug on an organ, or for obtaining information of the likelihood of recovery of an organ or part of tissue upon or during a period of insufficient vascular supply or during the progression of a chronic disease. The method may be used for discriminating between relevant therapy of an organ.Type: GrantFiled: March 23, 2000Date of Patent: June 27, 2006Inventor: Leif Østergaard

Patent number: 7034535Abstract: In a magnetic resonance imaging apparatus, a transmitting/receiving coil is attached to a patient at a region of interest and disposed within a static magnetic field, a radio-frequency magnetic field, and a gradient magnetic field and an image of the patient is obtained. A tabletop is used to move the patient in the static field in a horizontal direction within a horizontal plane and up and down in a direction that is perpendicular to the horizontal plane, a patient couch controller causing the tabletop to move, based on the position of the region of interest obtained from the image, so that the position of the region of interest is caused to coincide in three dimensions with the center of the static magnetic field and/or the gradient magnetic field.Type: GrantFiled: July 22, 2004Date of Patent: April 25, 2006Assignee: Kabushiki Kaisha ToshibaInventor: Hitoshi Yamagata
