Magnetic resonance measurement

摘要: In nuclear magnetic resonance spectroscopy spatial localization of the output signal is achieved by using gradient fields and radio-frequency inversion pulses to define slices through a sample from which obtained. The use intersecting allows field view be reduced region intersection study localized volume interest in sample. Conventionally, three orthogonal can defined energizing successively coils. With present invention combinations coils are energized simultaneously allow more closely conformed described interest. This simultaneous energization rotated relative axes and/or non-orthogonal alter shape at slices. Further, than may polyhedral defined. applicable many modern forms spectroscopy.
