摘要： A multi-layered inductor array is constructed to reduce and minimize variations in the inductance values and DC resistance values of a plurality of inductors contained in a multi-layered structure. In this multi-layered inductor array, four spiral inductors having an equal number of winding turns are aligned from the left end surface of the multi-layered structure to the right end surface thereof. In the direction in which the four spiral inductors are aligned, the lengths of the spiral portions of the inductors positioned at the central portion of the multi-layered structure are greater than those of the spiral portions of the spiral inductors positioned at both end portions thereof.

摘要： In order to provide a technique which can suppress coupling to homogenize the spatial distribution of an RF magnetic field and can improve penetration of the RF magnetic field into the subject, pad-like electric field conductors having a predetermined area are provided outside both ends of a rung conductor as a part of a configuration which forms a loop-like circuit and is driven as an antenna. An antenna device includes a sheet-like conductor, a rung conductor which is arranged at a predetermined distance from the sheet-like conductor, two electric field conductors which are arranged in both end portions of the rung conductor at a predetermined distance from the sheet-like conductor, and connection terminals which are transmission and reception terminals provided in the rung conductor and the sheet-like conductor. The rung conductor and the sheet-like conductor configure a loop circuit which resonates at a preset frequency.

摘要： 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.
