Try something like this

[rows, columns, numberOfSlices] = size(image3d);
for slice = 1 : numberOfSlices
    thisSlice = image3d(:,:, slice);
    baseFileName = sprintf('Slice %d.png', slice);
    fullFileName = fullfile(folder, baseFileName);
    imwrite(thisSlice, fullFileName);
end

To get them back, use imread(). To tack onto a 3D image, use cat(3, image3d, thisSlice).

thanks what about if i have 3 volumes each volume has different size and i want also to extract the images of 2d with .png is that possible or i should do that manually ex: 512*1024*128 and the second volume is 512*650*49 and the third is 512*1024*64 thanks for your reply

I worked on that code the slices are coming for some images and slices aren't coming for some segmented images. I attached the segmented image also.can anyone solve this problem

How can we use the Permute command for converting 3D to 2D?

[Image Analyst]

permute() does not do that. It basically just rotates the 3D volume so that rows are now columns, etc.
