IGRT and motion management during lung SBRT delivery

Area of Science:

• Radiation Oncology
• Medical Physics
• Image-Guided Therapy

Background:

• Patient motion is a significant challenge in lung stereotactic body radiation therapy (SBRT), potentially causing tumor misalignment.
• Deviations from the planned radiation setup can result in underdosing the tumor or overdosing healthy lung tissue.
• These inaccuracies can lead to acute toxicities, negatively impacting patient quality of life and survival outcomes.

Purpose of the Study:

• To highlight the critical role of motion correction techniques in lung SBRT.
• To emphasize the benefits of image-guided radiation therapy (IGRT) and motion management devices.
• To demonstrate the feasibility of integrating advanced technologies for improved patient care.

Main Methods:

• Utilizing image-guided radiation therapy (IGRT) for precise tumor targeting.
• Implementing motion management devices to account for patient movement.
• Integrating these technologies with clinical linear accelerators.

Main Results:

• Correction for patient motion, whether pre-treatment or intra-treatment, is achievable.
• Image-guided techniques and motion management devices effectively address setup deviations.
• The integration of these technologies is feasible within clinical workflows.

Conclusions:

• Image-guided radiation therapy (IGRT) and motion management are crucial for accurate lung SBRT.
• These techniques mitigate risks associated with patient motion, improving treatment efficacy.
• Implementing advanced motion correction strategies enhances patient care standards and quality of life.
