Hello, thank you for this great video. I have a question concerning the BED calculation examples early in the video (around the 14 and 20 minute mark). The thing I don't understand is that we are discussing normal tissue complications while determining the dose per fraction that is prescribed and delivered to the tumor. In the second example (20 minute mark) the 35 Gy in 5 fractions is the prescription to the PTV so how can we evaluate the toxicity to the normal tissue if we are only talking in terms of the absorbed dose to the tumor? Thanks!
