Abstract

Image-Guided Radiotherapy (IGRT) has revolutionized cancer treatment by enhancing the precision and accuracy of radiation delivery. However, the effectiveness of IGRT relies heavily on robust quality assurance (QA) measures to ensure patient safety and treatment efficacy. This study reviews current QA protocols and practices in IGRT, emphasizing their critical role in minimizing errors related to patient positioning, tumor localization, and dose delivery. We conducted a comprehensive analysis of QA methodologies, including imaging quality checks, verification procedures, and patient monitoring systems.

Findings indicate that implementing standardized QA protocols significantly reduces the risk of treatment-related complications and enhances overall treatment outcomes. Additionally, the integration of advanced imaging technologies, such as cone-beam CT and adaptive radiotherapy, further strengthens QA processes by allowing real-time adjustments during treatment.

This paper highlights the importance of a multidisciplinary approach in QA, involving radiation oncologists, medical physicists, and radiation therapists to foster a culture of safety and continuous improvement in IGRT practices. As the field continues to evolve, ongoing education and training are essential to keep pace with technological advancements and ensure that QA measures are effectively implemented. By prioritizing quality assurance in IGRT, healthcare providers can enhance the safety and effectiveness of cancer treatments, ultimately improving patient outcomes.
