An apparatus is described for sequentially applying selected excitation signals to selected slices of a physical object comprising: means for associating the integer i with a corresponding slice denoted by S/sub i/ for i=0, ..., (N-1), where N is a positive integer greater than 6; means for calculating the least positive residue r/sub k/ satisfying r/sub k/ identical to I/sub 0/+kX(MOD N) for k=0, ..., N-1 where I/sub 0/ is a selected integer and X is an integer relatively prime to N satisfying r(X)>2 and N-4(X)>2, where r(X) is the least positive residue congruent to X modulo N; and means, responsive to the residue r/sub k/, for applying a selected excitation signal to slice S/sub rk/, for k-0, ..., (N-1) in the order k=0, ..., N-1 so that a selected excitation signal is applied to slice S/sub rk/ before being applied to slice S/sub r(k+1)/ for k=0, ..., (N-2).
