Method and apparatus for nuclear magnetic resonance imaging using linear and resonant type amplifiers

摘要

An apparatus for nuclear magnetic resonance imaging capable of obtaining images at arbitrary cross sectional planes with an ultra high speed imaging method using a gradient field amplifier of resonant amplification type. The apparatus includes both a linear type amplifier having three channels and a resonant type amplifier having at least two channels. A nuclear magnetic resonance imaging is carried out with both of the linear and resonant type amplifiers supplying currents to the gradient coils.
