How do modern machines achieve precision when targeting a tumor that moves due to patient breathing?
Answer
Computer-guided imaging that adjusts beams in real-time
Modern radiation therapy employs advanced computer-guided imaging systems to monitor the tumor's location dynamically. These systems allow for the adjustment of radiation beams in real-time as the patient breathes or moves. This capability ensures that the high-energy radiation consistently targets the tumor mass with extreme accuracy, significantly reducing collateral damage to the surrounding organs compared to older, manual methods.
