  • Patent number: 10353042
    Abstract: According to one embodiment, an MRI apparatus includes a generator, an amplifier, and processing circuitry. The generator sequentially generates RF pulses comprising an RF pulse train defined in a pulse sequence. The amplifier amplifies the RF pulses sequentially inputted from the generator. The processing circuitry calculates a correction value, each time an amplified RF pulse is outputted from the amplifier, based on a difference between an output value of the amplified RF pulse and a reference output value. Further, the processing circuitry applies the correction value promptly to an RF pulse to be inputted to the amplifier, the RF pulse to be inputted to the amplifier being included in the RF pulse train and being generated after an RF pulse corresponding to the amplified RF pulse used for calculation of the correction value is generated.

  • Patent number: 9910119
    Abstract: A magnetic resonance imaging (MR) apparatus includes a mode switching part and an imaging system. The mode switching part is configured to put a circuit system consuming power into a shutdown state when a first trigger has been detected and to put the circuit system back into a startup state when a second trigger has been detected. The first trigger shows that MR imaging does not start for a certain period. The second trigger shows that MR imaging starts. The imaging system is configured to perform MR imaging by using the circuit system after being set to the startup state.

  • Patent number: 9486986
    Abstract: Disclosed is a multilayered-stretched resin film characterized in that on the back surface of a printable front layer (A) comprising a thermoplastic resin, an inorganic finepowder, and/or an organic filler is laminated a back layer (B) comprising a surface-treated inorganic finepowder and a thermoplastic resin comprising a hydrophilic thermoplastic resin, and in that the peel strength of back layer (B) is from 10 to 200 g/cm. The multilayered-stretched resin film affords good suitability for printing and embossing, that can be directly adhered to a wall or the like using a water-soluble adhesive without necessitating a backing of natural paper required by conventional wallpapers, and that can be readily peeled off the wall in a manner permitting recycling.
