I obtain a 4DCT scan at simulation with free breathing. I do not use abdominal compression, gating, or other motion management techniques. There is certainly room for more data here to fully evaluate the potential value of these techniques. But for now, I don't use them in this situation. In my expe...

Thanks for your answer!  Let me poke a bit further to stimulate discussion, since we’ve been chatting about this internally and haven’t gotten consensus yet. I’m very curious what you and others think about this. In this case, it sounds like you are essentially visualizing a...

I agree with Clifford, but both approaches are fine. I prefer simple solutions. I add 5mm cranial and caudal ...a “poor man’s ITV”....to an already generous CTV margin. Using 4DCTs for the treatment of microscopic disease always seemed like a long run for a short slide to me. We lo...
