  • Publication number: 20130214785
    Abstract: Images of two or more kinds of substances showing different chemical shifts, such as water image and metabolite image, are obtained without extending measurement time. For example, images of two or more kinds of desired substances showing different chemical shifts, such as water image and metabolite image, are obtained by one time of execution of an imaging sequence. In this execution, a pre-pulse is applied so that signals of the substances to be separated shift on the image, and magnetic resonance signals are received with receiver RF coils in a number not smaller than the number of types of the substances to be separated. An image reconstructed from the magnetic resonance signals is separated into images of the individual substances using sensitivity maps of the receiver RF coils. Then, correction is performed for returning the shifted image to the original position.

  • Publication number: 20130070194
    Abstract: An object of the invention is to provide a method and a system for manufacturing a liquid crystal panel, which allow more successful bonding of an optical film to a liquid crystal cell. A pressing force Fa per unit area applied when the optical film is pressed by the first roller and a pressing force Fb per unit area applied when the liquid crystal cell is pressed by the second roller satisfy the relation Fa>Fb. On the first roller side, the feed may fail to be stabilized due to the influence of tension fluctuations or vibration acting on the first optical film, so that air bubbles may occur. When the second roller side, where such an influence does not occur, contributes more to the feed of the liquid crystal cell, the liquid crystal cell can be successfully fed in the process of bonding the optical film thereto.

  • Patent number: 8400148
    Abstract: Magnetic resonance imaging apparatus enabling highly precise spectrum measurement even when resonance frequency changes during MRS or MRSI measurement. When a pulse sequence for suppressing water signals, and an MRS or MRSI pulse sequence are sequentially executed to carry out measurement using repetitive measurement for signal integration or repetitive measurement for phase encoding, signal Sig0 from water is measured with the pulse sequence for suppressing water signals in every repetitive measurement. When the resonance frequency of water deviates from an excitation band region, nuclear magnetization included in water molecules is not excited, so that water signal strength deceases, and therefore change of static magnetic field intensity can be detected by monitoring change of signal Sig0.
