Answer from: Radiation Oncologist at Academic Institution
The take home message for everyone is that motion management, regardless of the method used, is necessary. All patients should undergo 4DCT imaging in order to construct a "motion map" to quantify tumor motion in all directions. You can never assume that tumors will move in a predictable pattern. ...
