SBRT is typically provided in three to five treatment sessions, following a detailed treatment plan that integrates other leading technologies, such as PET-CT scanning, four-dimensional simulation (4-D Sim), and comfortable stabilization to minimize body motion during radiotherapy delivery.
The use of 4-D simulation allows for further advances in the targeting of lung cancer lesions by taking 'real time' movement into account while sparing additional normal tissues. The expectation is that side effects may be minimized further and that targeting will be more accurate. The total dose is often divided into two to five sessions, called fractions. This advanced technology offers a non-invasive, and potentially curative approach to lung tumors.
