Can tracking tumor movement during radiation make treatment more precise?

This trial investigates whether real-time motion management techniques—like triggered imaging and MLC tracking—can safely reduce the target margins used during radiotherapy for prostate and lung cancer. By adjusting the radiation beam to follow tumor movement, researchers aim to maintain or improve dose accuracy while potentially sparing healthy tissue. The study enrolls patients with localized prostate cancer or lung tumors and assesses both dosimetric and geometric accuracy from treatment data.
