摘要： A patient transfer board including an elongated board body that extends lengthwise along a longitudinal axis between leading and trailing ends of the board body. The transfer board has a top side and an underside of the board body. The underside includes first and second side edges that extend along the longitudinal axis. The underside includes alignment slots having respective openings at the first side edge. The alignment slots are defined by interior sidewalls. The alignment slots are configured to receive reference elements of the patient table through the respective openings when the transfer board is moved in a lateral direction that is generally transverse to the longitudinal axis. The sidewalls are configured to engage the corresponding reference elements and direct the transfer board toward a designated position.

摘要： A system and method including an apparatus for use in electrically loading RF coils of an MRI system is disclosed. The apparatus includes a polymer interdispersed with an electrically conductive additive such that the apparatus provides the necessary electrical loading of the RF coils for testing and calibration of the MRI system but is free of liquid. Furthermore, the apparatus is capable of providing the requisite electrical load in high magnet magnetic fields without introducing image distortion as a result of standing waves within the apparatus.

摘要： An arrangement is provided for supporting the inner and outer gradient coils of one or more gradient coil sets, the coils of each gradient coil set providing one of the orthogonal gradient magnetic fields for an MR imaging system. The arrangement includes an inner cylindrical coil form disposed to supportably carry an inner gradient coil of a coil set, an outer cylindrical coil form in coaxial spaced-apart relationship with the inner coil form disposed to supportably carry an outer gradient coil of the coil set, and a stiffening cylinder positioned between the inner and outer coil forms to divide the space therebetween into first and second volumes. A thermally conductive adhesive material, such as an epoxy containing alumina particulate material, is inserted into the first and second volumes to bond both the inner and outer coil forms to the stiffening cylinder, in order to hold the inner and outer gradient coils respectively carried by the coil forms in rigid fixed relationship with respect to one another.
