Title:
MAGNETIC RESONANCE IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/044299
Kind Code:
A1
Abstract:
In MRS measurement using magnetic resonance, when two areas in the same cross section are measured, the result with high accuracy is efficiently obtained while matching with the axis of a positioning image. When a plurality of areas which are localized (identified) by three slices which are orthogonal to one another and in which one or two slices are in common and one or two slices not in common are not overlapped out of the three slices which localize the areas are measured by using a press method, the slices not in common with an area which is selectively excited are excited by the number of slices in common therewith and an area group other than the area is brought into a heat balance state during the measurement of the area which is selectively excited by using a high frequency magnetic field, the phase of which is different by 180 degrees from that of a high frequency magnetic field used to excite the area which is selectively excited.
