Patent number: 6201394Abstract: A magnet for magnetic resonance imaging has an interior working space within the magnet frame sufficient to accommodate a physician and a patient. Because the physician is positioned inside the magnet frame, the physician has unimpeded access to the patient. Elements of the magnet frame desirably encompass a room, and the magnet frame may be concealed from view of a patient within the room. Preferred embodiments facilitate MRI imaged guided surgery and other procedures performed while the patient is being imaged, and minimize claustrophobia experienced by the patient.Type: GrantFiled: November 21, 1997Date of Patent: March 13, 2001Assignee: Fonar CorporationInventors: Gordon T. Danby, John Linardos, Jevan Damadian, Raymond V. Damadian

Patent number: 6975117Abstract: Magnet assembly for use in medical magnetic resonance imaging includes means for increasing flux generation in the gap region to provide the capability of scanning smaller volume regions of a patient at increased levels of scanning resolution. The means for increasing flux generation is mechanical or electromagnetic, is coupled to each of the polar regions and maintains the gap region sufficiently large and unobstructed to allow for access to the patient by several persons during scanning. Tapered outer walls of the polar region proximate the gap region further enhance accessibility to the patient during scanning.Type: GrantFiled: February 27, 2001Date of Patent: December 13, 2005Assignee: Fonar CorporationInventors: Raymond V. Damadian, Gordon Danby, James J. Persoons

Patent number: 8384387Abstract: A magnetic resonance imaging configuration to straighten and otherwise homogenize the field lines in the imaging portion, creating improved image quality. Through use of calibrated corrective coils, magnetic field lines can be manipulated to improve uniformity and image quality. Additionally, when the apparatus is composed of non-ferromagnetic materials, field strengths can be increased to overcome limitations of Iron-based systems such as by use of superconductivity. A patient positioning apparatus allowing multi-positioning is also disclosed.Type: GrantFiled: February 17, 2009Date of Patent: February 26, 2013Assignee: Fonar CorporationInventors: Raymond V. Damadian, Gordon T. Danby, Hank Hsieh, John W. Jackson, Mark Gelbien, William H. Wahl, Charles A. Green
