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： 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： 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. Alternatively, the reciprocatory mechanism means may comprise a stationary solenoid and a movable solenoid for being coupled to the needle. Preferably, a second stationary solenoid is provided and the moving solenoid is between the two stationary solenoids. Energization of the stationary solenoid or solenoids by an alternating current for example, and energization of the movable solenoid by a direct current, or vice versa, attracts and repulses the movable solenoid, causing reciprocation of the needle. Methods and systems using the vibration assisted needle device are also disclosed.
