What is SBRT?
SBRT stands for stereotactic body radiotherapy, a technique that delivers high doses of radiation to small tumor volumes.
How does the motion management protocol work?
The protocol uses noninvasive methods to control respiratory motion during radiation delivery, improving treatment accuracy.
What are the advantages of this technique?
It is non-invasive, requires less training, and improves patient comfort and treatment feasibility.
Who demonstrated the procedure?
The procedure was demonstrated by Yang-Bin Lin, a technician from the department.
What positioning is required for patients?
Patients are positioned supine with their arms over their heads for optimal treatment access.
Can this technique be used for other types of cancer?
While this study focuses on liver metastases, the principles may be applicable to other cancers requiring SBRT.
