those directions. Usually, for the first acquisition, the
pulse is halted once nuclei on the edges of the sample
have accumulated a pulse difference of 180
. When the
cycles are repeated larger phase shifts are deliberately
induced in each cycle in a progressive manner. This is
accomplished to increase the resolution in the longitu-
dinal direction, which for this method depends on the
number of the acquisitions.
