PURPOSE To create a dose response model that predicts lung ventilation change following radiation therapy, and examine the effects of out-of-phase ventilation. METHODS The dose response model was built using 27 human subjects who underwent radiation therapy (RT) from an IRB-approved trial. For each 4DCT, two ventilation maps were created by calculating the N-phase local expansion ratio (LERN ) using most or all breathing phases and the 2-phase LER (LER2 ) using only the end inspiration and end expiration breathing phases.
