"On treatment verification imaging" refers to a process used in image-guided radiation therapy (IGRT) to ensure the accuracy of the radiation treatment delivery. This involves capturing images of the patient in real-time or shortly before treatment to verify the positioning of the tumor and surrounding tissues. The goal is to minimize errors that could lead to inadequate treatment or damage to healthy tissue. The study guide for IGRT typically covers various imaging modalities, such as CT, MRI, or X-rays, and emphasizes the importance of image registration techniques to align pre-treatment images with current patient positioning. It also addresses the protocols for patient setup, the role of motion management, and the interpretation of imaging results to confirm that the treatment area is correctly targeted. Ultimately, effective on-treatment verification imaging is crucial for enhancing treatment efficacy, improving patient outcomes, and maintaining safety during radiation therapy. Understanding this process is essential for radiation oncologists, medical physicists, and dosimetrists involved in the planning and delivery of radiation treatments.
