    摘要： A method (10) for acquiring magnetic resonance data from a sample (50) to be analysed through a fixed geometry configuration coil suitable for transmitting radiofrequency signals ‘suitable for exciting said sample and/or detecting magnetic resonance signals from the sample (50) is described. The coil (100) comprises a plurality of current elements (20,21,22) and exhibits a frequency response comprising a plurality of resonant modes (M1, M2, M3) each associable to a respective resonant frequency (f1,f2,f3) depending on electrical features of the current elements (20,21,22), the current elements (20,21,22) comprising at least one current element having electrical features that may be regulated based on a respective control signal (S_CV0, S_CV1, S_CV2). The method provides for synthesising the control signal such as to obtain magnetic resonance data from a same sample for a given first resonant frequency of interest sequentially using resonance modes having different spatial field distributions.

    摘要： An RF coil is provided with a hollow-shaped outer conductive element and strip-shaped conductive elements disposed along the outer conductive element in the axial direction. The strip-shaped conductive elements are disposed with uneven intervals to secure an internal space at a position where the strip-shaped conductive elements are not disposed. In order to obtain uniform sensitivity at the center section of the RF coil, the strip-shaped conductive elements and the outer conductive element are electrically connected via capacitors of which capacitances are adjusted so that a magnetic field component perpendicular to the center axis should be generated at a desired resonance frequency, and the strip-shaped conductive elements are axisymmetrically disposed with respect to the center axis of the outer conductive element. As a result, a comfortable examination space in a tunnel type MRI apparatus is achieved without increasing the manufacturing cost of the MRI apparatus.
