Potential benefits of Dynamic Tracking

DRIFT

2. Real-time adaptation of periodic breathing motion and systematic drifts in patients with a variable and unpredictable magnitude of motion: lower lobe tumors and patients with poor pulmonary function*

3. IGRT for liver tumors that are difficult to visualize on cone beam CT

4. Increased efficiency of respiratory correlated treatments compared to gating
