Abstract: In order to reduce image quality deterioration due to static magnetic field inhomogeneity according to imaging conditions without increasing an operator workload, shimming current where static magnetic field inhomogeneity of a selected region is reduced is calculated, shimming is performed for the selected region using the calculated local Bo shimming current, and then an increment (RF-Phase) in an irradiation phase of an RF pulse that excites the selected region in a state where static magnetic field inhomogeneity of the selected region is reduced or a post-adjustment excitation frequency (f0?) that is an excitation frequency is calculated. These increments (RF-Phase) in an irradiation phase and post-adjustment excitation frequency (f0?) that is an excitation frequency correspond with each other in amount.

Abstract: A high-quality image is obtained using a two-dimensional selective excitation method even if the static magnetic field is not uniform. Therefore, non-uniformity of a static magnetic field of a region to be focused in particular in a selective excitation region excited by 2DRF is measured, and a result of the measurement is reflected in an imaging sequence using the 2DRF. For example, a resonance frequency of magnetization obtained from the measurement result is set as an irradiation frequency of the 2DRF. In addition, a shim gradient magnetic field is applied so as to correct the non-uniformity of the magnetization obtained from the measurement result. These are applied only in the imaging sequence using the 2DRF, and an irradiation frequency and a shim gradient magnetic field set in a conventional method are used in other imaging sequences.

Abstract: In imaging using 2-dimensional selective excitation pulses, regardless of applications thereof, a technique for obtaining a high quality image is provided. In the technique, a 2-dimensional selective excitation sequence is carried out while changing a coefficient for determining the cylinder diameter of a region excited by the 2-dimensional selective excitation sequence and a time difference for determining an offset position. The obtained excitation region and a desired region are compared with each other, and the coefficient and time difference with which the obtained excitation region and the desired region match each other are determined to be the optimum ones. The determination processing may be performed as an initial adjustment, may be performed according to need in each imaging, or may be performed on a per-application basis.
