Abstract
In an apparatus for examining human bodies by nuclear magnetic resonance to produce images of cross-sectional slices of such bodies, it is desirable to reduce the recovery time between scans at different angles. A suitable pulse sequence for examination with minimum dispersion is disclosed. Repetition of the sequence with inverted pulses to drive the spins back to equilibrium and reduce recovery time is also disclosed.
