I'm not sure if I obtained a CD from radiation, I may have, and I sent everything to MSK. Six month later. They finally returned my 400 page documents, 13 discs to me, but I don't know what was removed, kept, if any, and was mixed up. 
I looked at my PET/CT, which looked like a Christmas tree, and my first time thought cancer was everywhere lol. I can't make heads or tails if them, but the doctors are happy when I have a copy. 
I still can't figure the whole thing out. The primary tumor, I believe is referred to as the PTV, Primary Tumor Volume, which has max, min and mean dose in % on the set-up center image. The cumulative dose volume histogram has about 10 structures with the coverage, volume, min dose, max dose, mean dose, modal dose, median dose, one which appears went up to 75Gy, and is in %. On my treatment plan report it has the dose prescription, 
Target Volume                    Ptv70
Prescribed dose %             100%
Fractions                             F1
  Prescribed dose                7000.0 cGy (200.0Cgy/fractions)
  Dose at primary ref point   70000cGy (200.0cGy/fractions)
   Number of fractions.          35
