    Abstract: Regardless of the measurement conditions, the degradation of the image quality due to a vibrational error magnetic field, which is generated by the vibration of the mechanical structure of an MRI apparatus, is reduced. In order to do so, error magnetic field image data indicating an error magnetic field distribution is acquired on the basis of an echo signal measured using a pulse sequence having a test gradient magnetic field, a parameter value of a damped vibration function showing a vibrational error magnetic field is calculated using the error magnetic field image data, and a correction magnetic field is calculated on the basis of the calculated parameter value of the damped vibration function showing the vibrational error magnetic field.

    Abstract: There is provided a technique for securing a comfortable examination space in a tunnel type MRI apparatus without increasing the manufacturing cost of the MRI apparatus and sacrificing performance thereof. In an RF coil provided with a hollow-shaped outer conductive element and a strip-shaped conductive element disposed along the outer conductive element in the axial direction, meander lines constituting the strip-shaped conductive element are disposed at uneven distances from the outer conductive element to secure an internal space. In order to obtain uniform sensitivity at the center of the RF coil, the strip-shaped conductive element is constituted with N of connected meander lines, and length of the strip-shaped conductive element is adjusted so that, in the strip-shaped conductive element resonating at resonance frequency of the antenna, nodes are formed in a number of (M+1)×N−1, wherein M is 0 or a natural number of 1 or larger.

    Abstract: An MRI apparatus excellent in magnetic field generation efficiency is provided. According to this invention, a main coil (52) of a gradient magnetic field coil (13) is partially recessed to reduce the total thickness of a radio-frequency coil (11) and a gradient magnetic field coil (13). That is, the main coil (52) is designed in a tubular shape, and the diameter r1 at the center portion of the imaging space is larger than the diameter r2 of the main coil end portion. Accordingly, the RF coil (11) can be disposed to be near to the gradient magnetic field coil (13) side without lowering the magnetic field generation efficiency.

The full-length layers are divided into an inner-layer part including a half of the full-length layers and an outer-layer part including a remaining half of the full-length layers. At least one pair of the full-length layers is formed as a bias set layer in each of the inner-layer part and the outer-layer part by layering two bias layers with each other, with reinforcing fibers of the bias layers intersecting with each other at an orientation angle of ±θ° which fall in a range from ±25° to ±65° with respect to an axis of the golf club shaft. A straight layer is formed as an outermost full-length layer of the outer-layer part with reinforcing fiber thereof orienting at the range from 0° to ±10° with respect to the axis of the shaft.

    Abstract: An MRI apparatus capable of selecting an optional direction as a phase encoding direction and achieving a preferable S/N, when an imaging time shortening technique is applied. A receiver coil, used as a receiver coil of a vertical magnetic field MRI apparatus, is a combination of a first coil (solenoid coil) forming a current loop around the outer circumference of a test object, second coils forming even-numbered current loops, and third coils forming odd-numbered current loops, in the direction intersecting the plane of the current loop of the first coil. The second coil and the third coil are arranged in such a manner that, as for the current loops in the array direction thereof, a position where a sensitivity of one coil is minimized approximately coincides with a position where the sensitivity of the other coil is maximized, whereby electromagnetic coupling is suppressed.
