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： 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 belt buckle includes a housing having a base, first and second sidewalls projecting from the base so as to form a substantially U-shaped member and a lug member projecting from said base. There is also an electrical switching fastened to the base that has a pair of contact pins. A tongue plate preferably has a base portion and an elongated portion projecting from the base portion. The elongated portion may have a free-end opposite the base portion, a lower planar surface having a recess and mating member mounted at the free end thereof. In an assembled position the tongue plate is inserted in the housing such that the lug engages the recess and the mating member engages the contact pins.

The control kiosk may be advantageously located inside or outside the shielded room housing the MRI subsystem. The method comprises the steps of providing a control kiosk spatially separate from the MRI subsystem and positioning and viewing a patient within a patient-receiving space of the main subsystem.

摘要： A magnetic resonance imaging system having a patient support arranged for pivoting movement about a pivot axis and linear or sliding motion along a support axis transverse to the pivot axis is provided with a device for measuring the location of a patient feature to be imaged. The measured location is used to define coordinates for positioning the patient support. These coordinates desirably are used to automatically move the patient support from a loading position to an imaging position where the feature will be properly aligned with the field axis of the imaging magnet. The system simplifies patient positioning.

摘要： An electromechanical switch for use in a magnetic resonance imaging (MRI) apparatus is constructed of non-magnetic materials and includes a pivotable solenoid operative for moving a contact in response to forces created by interaction between passing through the electromagnet and the primary or static field of the MRI imaging magnet. The switch can be used to disconnect the RF receiver of the MRI apparatus from the receiving antenna during transmission of RF excitation signals.
