  • Publication number: 20150045653
    Abstract: A positron emission tomography (PET)-magnetic resonance imaging (MRI) apparatus according to an embodiment includes a gantry having a static magnetic field magnet, a gradient coil, and a radio frequency coil, a PET detector, and a moving mechanism. The static magnetic field magnet generates a static magnetic field in a bore having an approximately cylindrical shape. The gradient coil is disposed on an inner circumference side of the static magnetic field magnet and applies a gradient magnetic field to an object disposed in the bore. The radio frequency coil is disposed on an inner circumference side of the gradient coil and applies a radio frequency magnetic field to the object. The PET detector detects gamma rays emitted from a positron-emitting radionuclide injected into the object. The moving mechanism causes the PET detector in the gantry along the axial direction of the bore.

  • Patent number: 8947091
    Abstract: According to one embodiment, an MRI apparatus includes a probe unit and a control/imaging unit. The probe unit includes a probe, a converter, a compressor and a transmitter. The control/imaging unit includes a receiver, an expander and a reconstructor. The probe detects an RF echo signal generated in a subject by a magnetic resonance phenomenon. The converter digitizes the detected signal. The compressor compresses the digitized signal in accordance with a predetermined compression parameter to obtain a compressed signal. The transmitter generates a transmission signal to wirelessly transmit the compressed echo signal and sends the transmission signal to a radio channel. The receiver receives the transmission signal and extracts the compressed signal from the received signal. The expander expands the extracted compressed signal in accordance with the parameter to obtain the RF echo signal. The reconstructor generates a video signal regarding the subject on the basis of the obtained signal.

  • Publication number: 20140341643
    Abstract: A composite steel plate has a core material and steel plates on both sides of the core material and has mounting holes. A metal collar has a flange, a sleeve portion extending from the flange, and a locking portion extending from the sleeve portion and having a thickness thinner than that of the sleeve portion. The present invention provides a mounting structure for mounting the metal collar onto the composite steel plate. The locking portion is enlarged, and a first enlarged diameter portion is formed. Then the sleeve portion is enlarged, and a second enlarged diameter portion is formed. One steel plate is thereby clamped between the first enlarged diameter portion and the second enlarged diameter portion, and the other steel plate is thereby clamped between the second enlarged diameter portion and the flange. Thus, the metal collar is mounted onto the composite steel plate.

  • Publication number: 20140316671
    Abstract: A platoon travel system organizes a platoon having plural platoon vehicles traveling in two vehicle groups, in which a preset inter-vehicle distance is reserved between each of the platoon vehicles. When a new vehicle joins in the platoon, the platoon travel system adjusts the inter-vehicle distance by decelerating, among all platoon vehicles, deceleration target vehicles that are the platoon vehicles behind a join position in the platoon, which are included in a latter one of the two vehicle groups.

  • Publication number: 20140316865
    Abstract: A platoon travel system organizes and performs a platoon travel of plural vehicles along a preset travel route. The system has a grouping unit that divides the plural vehicles into a top group and a tail end group based on projection area information of the vehicles, and groups vehicles with a projection area in a first range to the top group and vehicles with a projection area in a second range to the tail end group, which is less than the first range. A final position determination unit determines a position of each of the plural vehicles in the vehicle groups based on the depart point information, positions the top group vehicles in an ascending order of depart point distances, and positions the tail end group vehicles in a descending order of depart point distances, thereby preventing deterioration of whole platoon energy consumption.
