摘要： A positioning system for an MRI system. One aspect includes a support member for moving a patient in a non-horizontal direction within a scanning area of the MRI system, a drive member for driving the support member, and a controller for controlling the drive member to position the patient at a desired location within the scanning area. One aspect includes a guide member attached to a floor beneath the scanning area for guiding a platform member along a first linear axis generally parallel to the floor and perpendicular to a magnetic field axis of a magnet of the MRI system. A controller controls a drive member to position the patient at a desired horizontal location within the scanning area. One aspect includes a frame, a platform member rotatably coupled to the frame. A controller controls a drive member to rotate the platform member and position the patient at a desired angle within the scanning area.

摘要： 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.

摘要： 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 allows multi-positioning of a patient within the calibrated and more uniform magnetic field lines.

摘要： Apparatus and methods for performing magnetic resonance imaging. In an embodiment the apparatus comprises a pair of elements spaced apart from each other along a horizontal pole axis so as to define a patient receiving space therebetween. A patient support device is located within the patient receiving space and is operable to accept a patient who enters the patient receiving space in an upright position, e.g., walking. In another embodiment the apparatus comprises a pair of elements supported within a frame. The frame includes upper and lower flux return members that are smaller in a vertical dimension than in a horizontal dimension. In another embodiment, the apparatus comprises a pair of elongated pole members that define an imaging volume having a longer dimension in a vertical direction than in a horizontal direction. An exemplary method includes performing a full body scan of a patient in an upright or sitting position.

摘要： 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.

摘要： 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.
