    Abstract: With minimizing extension of imaging time, the B1 non-uniformity reducing effect of RF shimming is maximized for an imaging section of an arbitrary axis direction and an arbitrary position. B1 distributions are measured for only several sections of one predetermined direction, and a radio frequency magnetic field condition that maximizes the B1 non-uniformity reducing effect for an imaging section of an arbitrary direction and an arbitrary position is calculated from the B1 distribution data. For example, after B1 distributions of only several sections of the AX direction are measured, the optimal radio frequency magnetic field condition for an imaging section of an arbitrary position for the AX direction is obtained by interpolation with optimal radio frequency magnetic field conditions calculated from B1 distributions of two sections near the imaging section, and the optimal radio frequency magnetic field condition for an imaging section of an arbitrary position for the SAG or COR direction is obtained by using only B1 values of a crossing region with the imaging section extracted from the B1 distributions.

    Abstract: This invention provides a carrying unit capable of changing the holding force of a carried object, suppressing the deformation amount of a carried object held by suction and dropping the carried object quickly at a predetermined place. A carrying unit has a workpiece holding face opposing a carried object and a carrying head equipped with a concave portion having an air guide face gently continued from a bottom face to a work holding face. A cylindrical nozzle which forms a slit for discharging air between the carrying head and the bottom face in order to discharge positive pressure air toward the air guide face from that slit is mounted on the carrying head such that it projects from the bottom face. A central portion of the cylindrical nozzle serves as a vertical nozzle comprised of a vertical hole which is open substantially in a vertical direction with respect to the carried object for supplying positive pressure or negative pressure air to the carried object and a flat portion perpendicular to the vertical hole.

    Abstract: An RF coil for MR Imaging that can change a resonance frequency easily and instantaneously in response to a nuclide to be imaged without exchange and adjustment and that also causes only small lowering of sensitivity. The RF coil has a sub coil for changing a resonance frequency of the transmitting/receiving RF coil for transmitting and receiving an MR signal between itself and a nuclide that is an object to be imaged. The sub coil is equipped with a switch, and at the time of switching-on, shifts the resonance frequency of the RF coil by changing an inductance value of the RF coil in a noncontact manner using inductance coupling.
