IGRT Therapy, or Image-Guided Radiation Therapy, is a cutting-edge technique used in radiation oncology that significantly enhances the precision and accuracy of radiation treatment delivery. It involves using various imaging technologies directly before and/or during each radiation treatment session to verify the exact position of the tumor and surrounding healthy tissues. This is crucial because tumors can move subtly due to normal physiological processes like breathing, bowel movements, or even slight shifts in patient positioning. Without IGRT, these movements could lead to radiation missing the target or hitting nearby healthy organs. Before each daily treatment, imaging devices built into the linear accelerator (the machine that delivers radiation) or located in the treatment room capture images of the patient's internal anatomy. These images, which can include X-rays, CT scans (cone-beam CT), or ultrasound, are then compared in real-time to the reference images taken during the initial treatment planning phase. If there's any discrepancy in the tumor's position or the patient's alignment, the treatment couch or the radiation beam itself can be precisely adjusted to ensure the radiation is delivered exactly where it's intended. This real-time feedback and adjustment capability allows for highly accurate targeting, which in turn permits radiation oncologists to use smaller margins around the tumor, delivering a higher, more effective dose to the cancer while sparing more healthy tissue. IGRT is particularly beneficial for tumors in moving organs (e.g., lung, prostate, liver) or for complex cases where extreme precision is required, leading to potentially better tumor control, reduced side effects, and improved patient outcomes compared to conventional radiation therapy.
