[Insight-users] read a meta image and write a volume to DICOM

[Diego Parada]

Hi,

You need set IOImage on the reader withi dicomIO (GDCMImageIO).

The difference difference between series and volume is that the serie is for 
example
IMR001.bmp
IMR002.bmp
IMR002.bmp
.
.
.
and the volume can be dicom multiframes or mhd format or raw format that 
they have 
a data 3Dmatrix whit the imaga slices.

The Dicom format can be mono frame and multiframe.
