With the objective of suppressing the adverse effect of residual magnetization
caused by encode ordering, twelve encode points are defined as a first segment
in order of decreasing distances from a center Cyz of a K space, twelve encode
points are next defined as a second segment in order of decreasing distances from
the center Cyz, and twelve encode points are defined as a third segment in order
of decreasing distances from the center Cyz subsequently to it. Serial numbers
are sequentially assigned to the encode points of the first, second, third and
fourth quadrants in the first, second and third segments in order of decreasing
distances from the center Cyz. Serial numbers are assigned subsequently in a manner
similar to the above. Furthermore, the K space is encoded in order of the serial
numbers to collect data.
