Patent number: 7573432Abstract: In one example, an antenna is disclosed comprising a first, outer conductor, at least one inner conductor within the first outer conductor, and a second outer conductor surrounding the first outer conductor. The second outer conductor may define a plurality of holes therethrough. The at least one inner conductor may comprise a plurality of inner conductors. At least two of the plurality of inner conductors may be connected to each other in series, across a capacitor. At least two of the plurality of inner conductors may be connected to each other in parallel, across a capacitor. The at least one inner conductor may be sufficiently surrounded by the first outer conductor to shield the inner conductor from receiving a radiofrequency signal.Type: GrantFiled: June 23, 2006Date of Patent: August 11, 2009Assignee: Fonar CorporationInventors: Gregory Eydelman, Raymond Damadian, Anthony Giambalvo

Publication number: 20080036463Abstract: A magnetic resonance imaging magnet includes a ferromagnetic frame. A pair of generally toroidal superconducting coil units overlie interfaces of side walls incorporated in the frame. Each coil unit may include a vessel having hollow support extensions extending into recesses in the side walls. The coil units may further include elongated, low-thermal conductance supports disposed within the support extensions. The frame may include pole stems projecting inwardly from the side walls, and the coils may be disposed in close proximity to the pole stems. Cryocoolers may be mounted to the frame so that the cryocoolers are substantially mechanically isolated from the coils of the coil units, but are in thermal communication therewith. The cryocooler mountings may be arranged for convenient servicing and installation of the cryocoolers.Type: ApplicationFiled: August 14, 2006Publication date: February 14, 2008Applicant: Fonar CorporationInventors: Hank Hsieh, Gordon Danby, Raymond Damadian, John Jackson, Hugh Wahl, Cristian Balica

Patent number: 7271689Abstract: A magnet structure produces a field within a magnet gap. The field is provided at least in part by a pair of permanent magnets that are fixed in place by a frame. The frame fixes a magnet assembly that is adapted to hold the magnetic material composing the permanent magnets, such that the quantity of the magnetic material can be adjusted to suit the particular application. The magnetic material can be provided in the form of discrete magnetic elements, such as magnetic “bricks”. The frame also functions as the flux collector and return. Accordingly, the general geometry of the magnet structure is fixed, and the amount of magnetic material, and therefore the magnetic field strength, is adjustable.Type: GrantFiled: March 28, 2005Date of Patent: September 18, 2007Assignee: Fonar CorporationInventors: Gordon Danby, John Jackson, Raymond Damadian, William H. Wahl, Anthony Tenore

Publication number: 20060197530Abstract: In one aspect, a magnet comprising a pair of pole supports spaced apart from one another and extending in a generally horizontal direction. The magnet includes a pair of flux return members extending between the pole supports so as to define a frame, each of the flux return members including a first columnar section that extends parallel to the polar axis and a second columnar section that extends perpendicular to the polar axis and projects towards the pole. In another aspect, a magnetic resonance imaging system comprises a ferromagnetic frame that is operative to support an upper pole member and a lower pole member along a vertical polar axis such that a gap is defined between the upper and lower pole members and an access floor that is isolated from the ferromagnetic frame and pole members for providing access to the gap.Type: ApplicationFiled: September 27, 2005Publication date: September 7, 2006Applicant: Fonar CorporationInventors: Raymond Damadian, William Wahl, Hank Hsieh, Gordon Danby, John Jackson, Jevan Damadian, Luciano Bonanni, Mark Gelbien, Keith Saboe
