We give a new algorithm for reconstructing a density f in the plane from its projections along those lines making an angle greater than a fixed δ > 0 with the x axis. Of course, the performance of the algorithm depends on δ and on the smoothness of f, but it appears to give a practical and simple solution to the problem whenever one exists. The basic idea, which seems to be new, is to make an affi...

The steady-state magnetizations in three versions of rapid NMR imaging using small flip angles and short repetition intervals are studied. It is shown that in the original version, the estimation using (1 - E1) sin α/(1 - E1 cos α) contains errors that depend on the increment of the phase rotation angle arising from the phase encoding process. The modified version of rapid imaging, where the phase...
