Respiration-Gated Radiation Therapy Synchronized Treatment

What is respiration-gated radiation therapy synchronized treatment?

As you inhale and exhale, your torso changes shape. This affects the position of your internal organs and the treatment area. Using respiration-gated radiation therapy allows us to:

  • Monitor your breathing
  • Target the radiation beam in real time with your breath

Why am I having respiration-gated radiation therapy synchronized treatment?

Your chest and torso move when you breathe. When we coordinate your treatment with your breathing, we:

  • Can focus a higher dose of therapeutic radiation on a smaller target
  • Often reduce your total treatment time
  • Reduce the risk of damage to healthy tissue

What type of technology does respiration-gated radiation therapy synchronized treatment use?

We use two techniques for respiration-gated treatment:

  • During MRI-guided radation therapy, we use the MRIdian ViewRay to deliver therapeutic radiation beams coordinated in real time with your breathing and the position of your internal organs.
  • We also combine surface-guided radiation therapy with a technique called deep-inspiration breath hold. This means we’ll ask you to inhale deeply and hold your breath for about 20 seconds while we deliver the therapeutic radiation. When you hold a deep breath, your heart shifts away from your chest wall, reducing its exposure to the radiation.

What conditions are treated using respiration-gated radiation therapy synchronized treatment?

We use respiration-gated radiation therapy synchronized treatment to treat breast cancer.
