How should the V10 or V12 be defined when evaluating intracranial SRS plans?   

Should it include the entire brain (normal brain + target) or just the normal brain (brain - target)?  How does the V10 or V12 constraint change when treating multiple lesions? Studies are not homogenous in the definiton of the volume when looking at V10 or V12.  How are most people approaching this out in practice?
