Hi, Michael,

You may want to try vtkImageReader to read the whole image data, 
for example in Tcl,

vtkImageReader reader
reader SetDataExtent 0 347 0 409 0 809
reader SetDataSpacing 1.0 1.0 1.0 
reader SetFileName "wholeimage.raw"
reader SetFileDimensionality 3
reader SetDataScalarTypeToUnsignedChar
reader Update
