  • Publication number: 20110231712
    Abstract: A CPU I/F decodes a signal transmitted from a CPU to a target location, and transmits the decoded signal to a mediating module mediating with the target location and to an access log recording unit. The access log recording unit generates an access log using the signal received from the CPU I/F, and stores the access log in an internal RAM. A DMA stores the access log stored in the internal RAM in a nonvolatile RAM when a system controller detects any occurrence of an error in the CPU.

  • Patent number: 7852076
    Abstract: The present invention provides a magnetic resonance imaging system capable of performing spectrum measurement even when a magnetic resonant frequency changes during MRS measurement. A time-varying rate of a water magnetic resonant frequency is measured in advance before the MRS measurement. The amount of change in water magnetic resonant frequency during the MRS measurement is predicted from the measured time-varying rate. With the predicted value as the reference, a transmission frequency of an RF magnetic field irradiated in a signal suppression pulse sequence, a transmission frequency of an RF magnetic field for excitation and inversion and a received frequency at the detection of a magnetic resonance signal in a sequence of the MRS measurement are respectively set. A high-precision spectrum measurement is hence enabled.

  • Publication number: 20100272337
    Abstract: While removing signals unnecessary for measuring signals from a metabolite, data required for eddy current correction are obtained in a short period of time. Signals from an unnecessary substance which is not an object of the measurement are removed, and phase data for correcting spectral distortion caused by an eddy current are obtained by a single measurement. Two kinds of frequency-selective pulses of which intensities are adjusted so that the signals from the unnecessary substance should have the same absolute values of intensities and opposite polarities are applied with changing intensities for every phase encoding for at least one axis, and the obtained signals are arranged in a k-space. By removing aliasing of image data obtained from the k-space data, signals from an unnecessary substance are removed, and phase data for eddy current correction are calculated by using a part of the k-space data.

  • Patent number: 7660676
    Abstract: When the nucleic-acid base sequence of A, C, G, and T (or U) is determined by interpreting fluorescent-light intensity waveform data acquired by measuring nucleic-acid fragments, it is desirable to determine, with a high-accuracy, the base sequence at a location at which the data interpretation is difficult. In order to accomplish this object, the data interpretation is performed by making reference to information acquired by performing the statistical processing to plural pieces of fluorescent-light intensity waveform data corresponding to already-known base sequences. This method allows the determination of the nucleic-acid base sequence at the above-described location.

  • Publication number: 20100026296
    Abstract: A magnetic resonance imaging apparatus enabling highly precise spectrum measurement even when resonance frequency changes during MRS or MRSI measurement is provided. When a pulse sequence for suppressing water signals, and an MRS pulse sequence or MRSI pulse sequence are sequentially executed to carry out MRS or MRSI 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 decreases, and therefore change of static magnetic field intensity can be detected by monitoring change of the signal Sig0.

  • Publication number: 20100013481
    Abstract: An object of the invention is to obtain a magnetic resonance spectroscopic image to which the MAC summation is applied with high accuracy and in short time, even though a phase characteristic distribution of the MAC has a spatial non-uniformity, in the MRSI measurement using a magnetic resonance imaging apparatus provided with a MAC. Using a non-water-suppressed image signal with high SNR, obtained in the non-water-suppressed measurement (a reference measurement) without water suppression, a correction value for correcting the phase distortion for the MAC summation is calculated on each pixel in each coil. After correcting a phase on each pixel in each coil of a main-scan image signal measured under suppressing water (water-suppressed image signal) using the corrective value, signal adding operation (summation) is performed. Then, a phase correction in a spectrum-axis is to be performed on the summed spectrum signal.
