    • Methods and apparatus for performing magnetic resonance imaging are disclosed. In one embodiment coil antennas for use with a horizontal field magnetic resonance imaging apparatus are placed in proximity to the scanning region to obtain magnetic resonance images. In accordance with another aspect of the invention the coil antennas are arranged so as to provide zero mutual inductance between the coils so as to increase the sensitivity of the measurement. Additional embodiments include quadrature coil antennas including two antennas, each having their vector fields substantially perpendicular to each other and to a static magnetic field. Methods for using the disclosed antennas in acquiring magnet resonance scans is also disclosed.

    • 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.
    • MRI系统的定位系统。 一个方面包括用于在MRI系统的扫描区域内的非水平方向移动患者的支撑构件,用于驱动支撑构件的驱动构件和用于控制驱动构件以将患者定位在期望位置的控制器 在扫描区域内。 一个方面包括附接到扫描区域下面的地板上的引导构件,用于沿着大体上平行于地板并且垂直于MRI系统的磁体的磁场轴的第一线性轴引导平台构件。 控制器控制驱动构件以将患者定位在扫描区域内的期望的水平位置。 一个方面包括框架,可旋转地联接到框架的平台构件。 控制器控制驱动构件以旋转平台构件并将患者定位在扫描区域内所需的角度。
