MRI SYSTEM APPARATUS TO PRODUCE ELECTRIC CURRENT

摘要

A magnetic resonance imaging system (10) includes a main field magnet (12) which generates a B 0 magnetic field through an examination region (14). One or more electric power generators (30) are disposed in the B 0 magnetic field. Each of the electric power generators includes at least one winding or coil (34) which is rotatably mounted for movement relative to the B0 magnetic field. A mechanical mechanism (60) such as vanes or propellers (62), a turbine (74) in conjunction with a fluid pump (72), or a motor (78) in conjunction with a drive shaft (76) and gear box (74), drive the at least one winding (34) to move in such a manner that it interacts with the B 0 magnetic field to generate an electric current.
