Tomotherapy
Everything You Need To Know About tomotherapy
Tomotherapy is both a radiation delivery system and a CT scanner that provides 3D images before each treatment. It’s a form of image-guided radiation therapy (IGRT) used to treat prostate, breast, lung, brain, head and neck cancers.
Tomotherapy uses intensity-modulated radiation therapy (IMRT) to match radiation intensity to tumor shapes, sparing more healthy tissue. It delivers radiation by rotating around the body, aiming targeted beams at tumors from many angles.
What Is Tomotherapy Used For?
Tomotherapy’s accuracy, modulation and 360-degree delivery make it ideal for tumors that are hard to reach or next to vital organs. It’s also used to treat multiple tumors at once and re-treat areas, with fewer side effects.
How Does Tomotherapy Work?
Mercy radiation oncology teams develop treatment plans using 3D images taken before treatment. This allows them to pinpoint tumor size, shape and location and determine radiation doses. The TomoTherapy system then calculates precise patterns, positions and intensity of radiation based on the prescribed doses. Treatment is delivered with highly targeted radiation beams directed at tumors from multiple angles.
Advantages of Tomotherapy
Tomotherapy offers several advantages, including:
- Real-time imaging of tumors for treatment planning.
- Targeted radiation precisely shaped to tumors.
- Higher-dose radiation delivery, potentially increasing treatment effectiveness.
- Less radiation of healthy organs and tissues.
