  • Patent number: 10852375
    Abstract: A magnetic resonance imaging configuration and methodology 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 and methodology allows multi-positioning of a patient within the calibrated and more uniform magnetic field lines.

  • Patent number: 7812607
    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.

  • Patent number: 7697971
    Abstract: 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.

  • Patent number: 7551954
    Abstract: A fixture such as a local receiver coil is secured to the patient support of a magnetic resonance imaging system so that the fixture remains in position relative to the support even when the support is in a vertical orientation. The positioning apparatus is arranged to allow adjustment of the fixture position, but to limit such adjustment so that the fixture cannot interfere with the poles or other elements defining the patient-receiving gap of the magnet during movement of the patient support.
