Image Guided Radiation Therapy (IGRT) represents a significant advancement in the field of radiation oncology, incorporating real-time imaging technologies into the treatment process to enhance the precision and efficacy of cancer treatment. Unlike traditional radiation therapy, which typically relies on imaging conducted prior to treatment and fixed patient positioning, IGRT employs frequent imaging both before and during radiation delivery. This approach enables healthcare providers to accurately locate tumors and make necessary adjustments to patient positioning, thereby ensuring that radiation is precisely aimed at the target while sparing surrounding healthy tissues from unnecessary exposure.
