You can try to use MetaImageIO, you can construct an .mhd file , and 
then read it in usual way ( using itk::ImageFileReader )
There is an application MetaImageImporter in  InsightApplications, that 
will create and .mhd file for you.
In short, mhd file is a text file of the following format:

NDims = <number of dimensions>
DimSize = <x size> <y size> <z size>
ElementSpacing = <x spacing> <y spacing> <z spacing>
Position = <x origin> <y origin> <z origin>
ElementByteOrderMSB = <False if the data in PC byte order>
ElementNumberOfChannels =  <number of channels per voxel>
ElementType = <data type: MET_UCHAR, MET_USHORT, MET_UINT MET_FLOAT 
MET_DOUBLE>
ElementDataFile = <name of the RAW file>
