IGRT Radiation Therapy: What It Is, Uses & Benefits

Precision in Motion: How Image-Guided Radiation Therapy (IGRT) is Transforming Cancer Care

For decades, the greatest challenge in radiation oncology has been a moving target. Human bodies are dynamic: lungs expand and contract with every breath, bladders fill, bowels shift, and tumors themselves can shrink or change position over the course of a multi-week treatment cycle. Traditional radiation therapy relied heavily on external skeletal landmarks and pre-treatment scans taken weeks prior, leaving a margin of error that often exposed healthy surrounding tissue to unnecessary radiation.
