Welcome back to our deep dive on the core principles of radiation physics. This is Part B of our comprehensive physics review. In Part A, we built the foundation, exploring everything from the atom and radioactive decay to the complex machines that generate our clinical beams.Exactly. We covered the "what" of radiation. Now, in this episode, we're going to cover the "how." We'll see how we measure, plan, and deliver dose with these beams. We'll get into dosimetry, M.U. calculations, advanced techniques like I.M.R.T. and V mat, and wrap up with crucial concepts in imaging and safety.
