  • Patent number: 6541973
    Abstract: 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.

  • Patent number: 6469508
    Abstract: A method of fabricating a coil for a magnetic resonance imaging magnet is disclosed. The method includes providing a plurality of windings each having an axis. A conductor is arranged in a plurality of turns extending in a spiral between the inner end and the outer end of the windings. The turns of each outward winding and inward winding are arranged so that a point moving along the turns in a first direction of rotation about the axis of the outward winding moves from the inner end towards the outer end, and the outer end towards the inner end, respectively. The method further includes superposing the spiral windings one above the other so that the windings are substantially coaxial with one another and electrically connecting the windings in series with one another.

  • Patent number: 6677753
    Abstract: A magnet for magnetic resonance imaging has a box-like ferromagnetic frame with vertical side walls, poles connected to the side walls and top and bottom walls forming flux return structures between the side walls. The frame has open front and rear sides defining patient entry openings, and has top and bottom openings in the top and bottom walls. A patient can be positioned in a vertical, horizontal or intermediate orientation within the frame. When the patient is in the vertical orientation, the patient can be raised or lowered so that parts of the patient's body protrude into the top or bottom openings, so as to align any part of the patient's body with the poles. The apparatus allows imaging of any part of the anatomy while the patient is in a standing position.

  • Patent number: 6404202
    Abstract: A magnetic resonance imaging (MRI) magnet in combination with a mobile patient-positioning device, including a patient support and a method of using same for positioning patients for MRI scanning. The patient support is rotatable through a range of orientations. The patient disposed on the patient-positioning device in a predetermined orientation can then be moved horizontally into and out of a patient-receiving space in the MRI magnet at the predetermined angle or orientation. A preferred embodiment includes a plurality of patient-positioning devices in which a series of patients can be placed in a ready state while one patient is within the patient-receiving space. As an alternative embodiment, the patient may be moved vertically into position for MRI scanning by way of an elevator which is actuatable from the floor below the patient receiving space. This elevator also may be used in combination with the patient-positioning device.

  • Publication number: 20090256573
    Abstract: 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.
