    摘要: An apparatus and method for mounting cables within a magnetic resonance imaging (MRI) system are provided. One apparatus includes a cable assembly having a rigid support structure defining a channel with a cross-section and an electrical cable having a cross-section smaller than the cross-section of the channel. The electrical cable is secured within the channel of the rigid support structure, with the rigid support structure configured for coupling to a stationary component of the MRI system to resist movement from a movable component to which the electrical cable is connected.

    摘要: An MRI apparatus and method comprises an MRI system having a plurality of gradient coils positioned about a bore of a magnet, and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images. The magnet comprises a main coil former and a shield coil former arranged radially around the bore of the magnet, wherein a radius of the shield coil former is greater than a radius of the main coil former. The magnet also includes at least one main coil affixed to the main coil former, at least one shield coil affixed to the shield coil former, and at least one structural member affixed to the main coil former and to the shield coil former to provide structural support and enable longitudinal alignment adjustment between the main coil former and the shield coil former.
