Embodiment Construction
[0041] refer to figure 1 , the main magnetic field controller 10 controls the superconducting or resistive main magnet 12 to generate a substantially uniform, temporally constant main magnetic field along the z-axis through the examination volume 14 .
[0042] Magnetic resonance generation and manipulation systems apply a series of RF pulses and switched magnetic field gradients to flip or excite nuclear magnetic spins, induce magnetic resonance, refocus magnetic resonance, manipulate magnetic resonance, spatially encode or otherwise encode magnetic resonance, such that Spin saturation etc. to perform MR imaging.
[0043]More specifically, gradient pulse amplifier 20 applies current pulses to selected ones of pairs of whole body gradient coils 22 to generate magnetic field gradients along the x, y, and z axes of examination volume 14 . A digital RF frequency transmitter 24 transmits RF pulses or bursts to a whole body RF coil 26 for transmitting RF pulses into the examination...
