摘要： 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.

摘要： 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.

摘要： A high-speed magnetic resonance spectroscopic imaging method for obtaining information relating to an object placed in a space by irradiating the object placed in the space applied with a static magnetic field and field gradients in three different directions so as to excite a nuclear spin in the object. At least one of the field gradients is applied while inverting a sign thereof periodically and a magnetic resonance signal generated by excitation of the nuclear spin is measured. A Fourier transform is applied to the measured magnetic resonance signal thereby to obtain a chemical shift image and a measurement spectral bandwidth is set to a value not larger than a frequency difference between two different chemical shifts having frequencies remotest from each other among a plurality of chemical shifts intended to be measured, the measurement spectral bandwidth being determined by a reciprocal of an inversion period of the field gradient which is applied while inverting a sign thereof periodically. The method enables setting of spatial resolution and spectral bandwidth independently.

摘要： A mount member is fixed to a support member by first and second fastening members, and a caliper is mounted to the mount member by first and second guide members. A motor axis of an electric motor and an axis of a shaft member configured to press a pressing member are different from each other. The electric motor is fixed to the caliper. When viewed from an axial direction of the first guide member, the motor axis is positioned inside a fastening quadrangle having four corners corresponding to positions of respective axes of, and is perpendicular to the axis, and the motor axis is orthogonal to a plane of the fastening quadrangle. As a result, there may be provided a vehicle electric braking device in which an axial direction dimension may be reduced to suppress an amplitude caused by vibration, and components sensitive to vibration influence are appropriately arranged.

摘要： An object of the present invention is to suppress artifacts generated by correction of spectral distortion induced by eddy currents in MRI devices with a simple method, and thereby improve accuracy of the correction. In the eddy current correction processing for correcting spectral distortion caused by an eddy current using phase values of FID signals of a substance showing higher signal intensities compared with a metabolite as an object of measurement, phase jumps of the phase values used for the correction are corrected beforehand. In the correction of the phase jumps, small phase change amount points are identified by using primary time differential values of the phase values, and the other points are identified as a phase jump generation region. Then, the primary time differential values corresponding to the identified phase jump generation regions are excluded. The phase jump generation regions are identified as regions where the primary time differential value changes in an amount not smaller than a threshold value defined beforehand within a range defined beforehand.
