Patent number: 7268553Abstract: 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: December 12, 2005Date of Patent: September 11, 2007Assignee: Fonar CorporationInventors: Raymond V. Damadian, Gordon Danby, James J. Persoons

Patent number: 6884211Abstract: A medical device is provided for improving the intensive care of high-risk newborns. The device comprises a tempered air closed circuit enclosing a neonatal capsule and comprising a dome composed of two concentric layers defining an intra-dome space therebetween, through which tempered air can circulate, to maintain the temperature in the intermediate artificial environment created between the neonatal capsule and the tempered air closed circuit. A continuous ventilation circuit is provided comprising air and oxygen inlet lines and a mixture outlet line, to administer a continuous and regulated air flow of filtered, oxygenated, tempered and humidified air to the newborn child inside the neonatal capsule. A set of doors may be provided through the neonatal capsule and dome, to provide access inside the neonatal capsule.Type: GrantFiled: July 11, 2003Date of Patent: April 26, 2005Assignee: Pontifica Universidad Catolica Del PeruInventors: Claudio Bruno Castillón Lévano, Eduardo Ajito Lam

Patent number: 6727698Abstract: An MRI antenna comprises an inner conductor with first and second ends and an outer conductor with first and second ends. The outer conductor substantially surrounds the inner conductor. The inner and outer conductors define a region for receiving a body part and the inner conductor is electrically connected to the outer conductor. The inner and outer conductors may be connected in a variety of manners. For example, the inner conductor may be directly electrically connected to the outer conductor. The inner conductor may also be connected electrically to the outer conductor through one or more capacitors. A magnetic resonance imaging system including the antenna of the present invention is also disclosed.Type: GrantFiled: December 15, 2000Date of Patent: April 27, 2004Assignee: Fonar CorporationInventor: Gregory Eydelman

Patent number: 6702761Abstract: A vibration assisted needle device is disclosed for use in medical procedures, such as needle aspiration biopsies. Reciprocation of the needle, such as a biopsy needle, eases the advance of the needle through tissue, penetration of the site of interest and the collection of sample at a site of interest. The device comprises a housing defining a chamber, a needle support external to the chamber for supporting a needle and a mechanism in the chamber for causing reciprocatory motion of the needle support. The needle support is preferably external to the housing. A syringe support may be connected to the housing for supporting a syringe. The reciprocatory mechanism may comprise means for converting rotational motion into reciprocating motion, such as a bearing or a rotor with a circumferential, angled groove on its surface, coupled to the needle support. The bearing or the rotor may be driven by a rotational motor, preferably located outside of the housing, or by a hydraulically driven turbine within the housing.Type: GrantFiled: March 6, 2001Date of Patent: March 9, 2004Assignee: Fonar CorporationInventors: Jevan Damadian, Jan Votruba, Mark Gelbien, Michael Votruba

Patent number: 6636040Abstract: An MRI antenna is disclosed comprising a first coaxial cable unit comprising a first inner conductor with first and second ends and a first outer conductor substantially surrounding the inner conductor. The first outer conductor has first and second ends. The first coaxial cable unit has a concave curvature facing a first direction. A second coaxial cable unit is provided comprising an inner conductor with first and second ends and an outer conductor substantially surrounding the inner conductor. The outer conductor has first and second ends and the second coaxial cable unit has a concave curvature facing a second direction opposite the first direction. The concave curvature of the first and second coaxial cable units generally face each other to define a region for receiving a body part. The first end of the first inner conductor is connected to the first end of the second inner conductor through a first capacitor.Type: GrantFiled: December 15, 2000Date of Patent: October 21, 2003Assignee: Fonar CorporationInventor: Gregory Eydelman

Patent number: 6622441Abstract: The present invention is a window frame wherein all of the structural members are formed with the same substantially identically-shaped configuration a metal extrusion. A plurality of structural members are arranged to form a supporting structure. Each structural member has a U-shaped channel defined by a base portion having a first arm and a second arm spaced apart on opposite lengthwise sides of said base portion. The first and second arms extending from said base portion have end portions turned inward and extending in a direction toward said base portion. Fasteners detachably secure the plurality of structural members into a configuration adapted to detachably mount a translucent barrier within the supporting structure formed by the structural members.Type: GrantFiled: May 9, 2002Date of Patent: September 23, 2003Inventor: Allan S. Miller

Patent number: 6621433Abstract: A receiver for a resonance signal of a magnetic resonance imaging system generates a baseband signal for image processing by dividing a raw resonance signal among multiple parallel channels, each amplified at a respective gain. A digital channel selector determines, at any given moment, a lowest-distortion channel to be further processed. Amplitude and phase error compensation are handled digitally using complex multipliers, which are derived by a calibration, based on a simple Larmor oscillator, which can be done without the need for a sample and without repeating when measurement conditions are changed. One of the important benefits of the invention is that it provides for gain selection without repeated calibration steps. This is particularly important in systems that employ fast imaging techniques such as fast spin echo, where the invention can speed imaging substantially.Type: GrantFiled: June 22, 2001Date of Patent: September 16, 2003Assignee: Fonar CorporationInventor: David Hertz

Patent number: 6549009Abstract: A magnetic resonance imaging (“MRI”) simulator for evaluating an MRI device comprises sections for being selectively coupled to the corresponding portions of the MRI device. Data representative of a previously imaged object is provided to the portions of the MRI device, for processing. The results of the processing are evaluated to determine whether portions of the MRI device are operating properly. Methods of evaluating an MRI device and an MRI device incorporating such a simulator are also disclosed.Type: GrantFiled: January 13, 2000Date of Patent: April 15, 2003Assignee: Fonar CorporationInventors: David Hertz, Michael B. Knepper
