you can use vtkImageImport[1] to import data from a C array.
E.g. in C++:

    short *data = ...

    importerROI->SetImportVoidPointer( data );
    importerROI->SetDataScalarTypeToShort();    // default
    importerROI->SetWholeExtent( 0, Z-1, 0, Y-1, 0, X-1 );
    importerROI->SetDataExtentToWholeExtent();

To set the orientation of your image properly, see the class
documentation.
