Convert 2D siemens mosaic MRI image to multi slices

I have a siemens mosaic MRI image, and it's 512*512 unit-16 matrix after I use dicomread to read it. It contains 60 slices and the size for each slice is 64*64. I want to convert the montage image to slices. Is there some toolbox to do that? Thanks!

slices = mat2cell(MosaicArray, 64 * ones(1,size(MosaicArray,1)/64), 64 * ones(1,size(MosaicArray,2)/64) );
Now you would need to get rid of 4 of the items, but at the moment I do not know which 4 are the empty ones and I do not know whether the unraveling should be along the rows or down the columns. Probably it should be
slices = transpose(slices); %rows become priority
slices(61:end) = []; %remove the 4 empty slices

I am having the same problem. I have some mosaic 2D dicom data with dimensions 1024x1024x1 and I want to write them as multi-slice mosiac dicom data with dimensions 128x128x64.
After using:
slices = mat2cell(MosaicArray, 128 * ones(1,size(MosaicArray,1)/128), 128 * ones(1,size(MosaicArray,2)/128) );
how can I save these slices into the final desired mosaic dicom format?
