There are some binary images I am planning to segment. Once that is done, I would like to essentially stack all the image to form a 3-D object and perform some quantification. Is this possible in Matlab?

Yes.

binary3d = cat(3, binary1, binary2, binary3, binary4);

I am assuming that for a series of stacked images hundred's long that I can just loop it for the stack?

Yes, but it would be best (faster) to preallocate and overwrite slices rather than append.

[rows, columns] = size(binaryImage1);
% Allocate space for 537 images.
binary3d = false(rows, columns, 537); 
% Loop inserting all images into the 3D image.
for k = 1 : 537
    thisImage = .... however you get the k'th image
    binary3d(:,:,k) = thisImage;
end
