Each slice is one plane of a three-dimensional array. Of course each slice can be a one voxel thick three-dimensional array if it traverses the third-dimension of if you associate it with a thickness. Typically, for CT/MRI images, you would stack multiple planes together and then analyze the volume created by them. This would be required for mcubes since they expect a "cube".

If you have the images in DICOM format, you can use 'dicomread' to read the images.
