Radiation Therapy, through the linear accelerator, combines imaging, beam delivery and sophisticated motion management to accurately and precisely target tumors with speed.
Here are 5 quick facts:
- DMG’s linear accelerator rotates around the patient to deliver a prescribed radiation dose from nearly any angle.
- An accessory called a multileaf collimator (or MLC) is what shapes the beam. It has 120 computer-controlled “leaves” or “fingers” that create apertures of different shapes and sizes. The leaves sculpt the beam to match the 3‑D shape of the tumor. These can move and change during treatment to target the tumor and minimize dose to the surrounding healthy tissue.
- Real-time imaging tools allow clinicians to “see” the tumor they are about to treat, giving them the confidence that tumors can be targeted with accuracy measured in millimeters.
- The system includes a new “gated” option for synchronizing beam delivery with respiration. This helps maintain accuracy as the system changes its targeting whenever tumor motion is an issue, for example during lung cancer treatments.
- Patients can receive the treatment that is best suited for their specific clinical circumstances because DMG’s linear accelerator can be used for many forms of advanced treatment techniques including image-guided radiotherapy (IGRT), intensity-modulated radiotherapy (IMRT) and RapidArc® radiotherapy (SBRT/SRS) technology.
