Need some extra slides added to my PowerPoint. I have a presentation however, the PowerPoint isn’t long enough to cover the 10-15 minute time slot. Please add a few slides discussing the use and evolution of radiation therapy machinery
I have a book that has some info I can attach the chapter
I also felt like it needed a little more info the machines especially on how beneficiary the newer machines are. I hope the chapter I’ve attached helps but you can use another source as well
