IGRT uses real-time imaging before and during treatment to precisely deliver radiation, even as tumors shift or change in size over time.
Image Guided Radiation Therapy (IGRT) is an advanced technique that enhances the accuracy of radiation treatment by using frequent imaging. These images are taken before or during each session to help ensure that the radiation is delivered precisely to the tumor—especially important when tumors shift naturally due to breathing or change size during the course of treatment.
At Salter Radiation Oncology, we use state-of-the-art imaging technology built into or positioned near the linear accelerator—the machine that delivers your radiation. Before each session, updated images are compared to earlier scans taken during your initial planning (simulation). This allows your care team to make real-time adjustments to your positioning or treatment plan to maintain pinpoint accuracy.
IGRT allows us to deliver higher doses of radiation directly to the tumor while minimizing the impact on surrounding healthy tissue. This results in:
IGRT is especially valuable when treating cancers located near vital or sensitive organs—like the heart, kidneys, or spinal cord. It’s also commonly used for tumors in areas that move with the body, such as the:
At Salter Radiation Oncology, we know that technology alone isn’t enough—it’s how you use it that matters. That’s why our team, led by Dr. Susan Salter, uses IGRT in combination with decades of clinical experience to create treatment plans tailored to you. We review imaging results at every stage to make sure your care is as precise and safe as possible.
