New imaging technique may reduce lung damage from cancer radiation

This study looks at whether a special CT scan (4DCT) can help doctors avoid giving too much radiation to healthy parts of the lung during lung cancer treatment. Researchers will compare standard radiation plans with new plans that protect well-working lung areas. The goal is to see if this approach lowers the risk of lung injury from radiation. The study uses existing data from 202 patients and does not involve any new treatments or procedures.
