Abstract:
A magnetic resonance imaging system comprising:a lower body having one magnetic pole for generating a magnetic field;an upper body having another magnetic pole for generating a magnetic field; anda pair of support posts forming a magnetic circuit for passing magnetic flux from one magnetic pole to the other magnetic pole through a first space, said support posts being connected at sides of said lower body and said upper body and symmetrically disposed in a horizontal level thereof,wherein said lower body having a first flat surface, a first outer peripheral surface formed on an upper surface thereof and a second outer peripheral surface vertical to said first flat surface,wherein said upper body having a second flat surface, a third outer peripheral surface formed on an upper surface thereof and a fourth outer peripheral surface vertical to said first flat surface,wherein said second flat surface of said upper body is arranged opposite said first flat surface of said lower body and said upper body is formed so that a forward side thereof has an arc-like shape,wherein said fourth outer peripheral surface of said upper body is vertical to and made circular concentric with said second flat surface,wherein said fourth outer peripheral surface of said upper body has a larger diameter than that of said second flat surface,wherein said upper body has an oblique surface made oblique inwardly between said second flat surface and said third outer peripheral surface, andwherein said upper body has at least one operating portion for operating an operation of a bed or an examination.
