You probably don't want to do that anyway, unless you use lossless jpeg2000 format. Use PNG for lossless compression
for sliceIndex = 1 : size(image3d, 3)
    thisSlice = image3d(:,:,sliceIndex);
    filename = sprintf('Slice #%d.png', sliceIndex);
    imwrite(thisSlice, filename);
end
image3d is your 3-D image array.
