| Research Abstract |
Four dimensional computed tomography (4D-CT) based lung ventilation imaging was developed to enable us to create lung ventilation based treatment planning easily. Next, we validated the 4D-CT derived ventilation using Tc-MAA single positron emission CT imaging, indicating the high psychological accuracy of 4D-CT ventilation. Furthermore, our results demonstrated that a functional plan of SBRT reduced the dose in the high-functional regions without a change in the total lung or PTV, indicating that this technique can be safely used for SBRT.
