Hello Consuelo,

you can attach several DoseActor
to the same CT image, each DA may have its own pixel size and location
within the CT image: use setSize (bounding box size) & setResolution (nb of
pixels), and setPosition. DA may overlap if needed. Each will output an
independent mhd image with correct spacing/size/origin.

PS: a new version of VV (1.4) is available on http://vv.creatis.insa-lyon.fr
