Gradient field switch for improved magnetic resonance imaging/spectroscopy system |
摘要 |
A gradient field switch, for use in an improved nuclear magnetic resonance imaging and spectroscopy system, includes a control portion and a switching portion. The switching portion receives a plurality of magnetic field gradient signals and connects each signal to an associated one of at least the same plurality of outputs. The exact pattern of input-output interconnections is established by the control portion responsive to data received after the presence of a reset signal. By appropriate control data input, the gradient field signals can be routed to axes of a predetermined coordinate system, such that images of a sample can be obtained from several directions, responsive to command signals and without requiring physical movement of the sample being imaged.
