Consider the example:
% create an array
s = [5 7 3];
A = reshape(1:prod(s),s)
% create a vector containing all pages in the first column
B = reshape(A(:,1,:),[],1,1)

If you have a 153x1 vector, you don't have 51x71x3=10863 elements to fill that array. They've been discarded.
You can recreate the original 51x1x3 column:
% create an array
s = [5 7 3];
A = reshape(1:prod(s),s)
% create a vector containing all pages in the first column
B = reshape(A(:,1,:),[],1,1)
% recreate the 51x1x3 part of A
C = reshape(B,[],1,s(3))
