Image-Guided Radiation Therapy (IGRT)
Image-Guided Radiation Therapy (IGRT) is a form of radiation therapy that uses advanced imaging techniques during treatment to enhance precision and accuracy.
Image-Guided Radiation Therapy (IGRT) is a form of radiation therapy that uses advanced imaging techniques during treatment to enhance precision and accuracy. IGRT is designed to track and adjust for changes in tumor position and patient anatomy during the course of treatment, allowing for more precise targeting of the tumor and sparing of surrounding healthy tissue.
Key Features of IGRT:
- Real-Time Imaging: IGRT uses advanced imaging technologies such as X-ray, CT, or MRI during treatment to visualize the tumor and adjust the radiation beams accordingly.
- Adaptability: The real-time imaging allows for adjustments in the radiation delivery based on changes in tumor size, shape, or position, as well as patient movement.
- Enhanced Accuracy: By tracking the tumor's position and patient anatomy, IGRT increases the accuracy of radiation delivery, minimizing the dose to surrounding healthy tissue.
Benefits of IGRT:
- Improved Targeting: IGRT ensures that the radiation dose is delivered precisely to the tumor, reducing the risk of damage to healthy tissues.
- Increased Treatment Effectiveness: The ability to adapt the radiation dose based on real-time imaging can enhance the treatment's effectiveness.
- Minimized Side Effects: By targeting the tumor more accurately, IGRT can reduce side effects and complications.
- Versatile Applications: IGRT can be used for various types of tumors in different parts of the body.
Applications of IGRT:
- IGRT can be used to treat a wide range of tumors, including those in the:
- Brain
- Head and neck
- Breast
- Prostate
- Lung
- Gastrointestinal tract
- Gynecological organs
- Spine
Treatment Planning and Delivery:
- Planning: Before treatment begins, patients undergo imaging scans to create a detailed treatment plan that maps the tumor's location, shape, and size.
- Delivery: During treatment, imaging is used to monitor the tumor's position and patient anatomy. The radiation beams can be adjusted in real-time to ensure accurate delivery.
Conclusion:
Image-Guided Radiation Therapy (IGRT) is a valuable approach to radiation therapy that improves precision and accuracy. By using advanced imaging techniques, IGRT can enhance the effectiveness of treatment, reduce side effects, and offer more versatility in treating various types of tumors. It is an important tool in modern radiation oncology.
