Abstract:
This invention provides a receiving coil that allows a high-quality image of high depth sensitivity to be obtained during vertical magnetic field MRI without limiting selection of a cross section to be imaged and of a phase-encoding axis. A subject's field of view is broadened without deterioration of the coil characteristics. Two orthogonal solenoid coils (3-1 and 4-1) and sub-coils (5-1, 6-1, and 7-1) whose sensitivity distributions each become an odd function in an x-direction, a y-direction, and a z-direction, respectively, with respect to the origin of the sensitivity distribution of each of the solenoid coils are used as multiple sub-coils to construct the receiving coil. This receiving coil is suitable for a high-speed imaging method in which an image is acquired using reduced phase encoding and the image is reconstructed using image folding. In addition, the subject's field of view can be broadened by arranging conductors of the coil appropriately.
