What is SBRT?
Stereotactic body radiotherapy (SBRT) is a form of radiation therapy that delivers high doses of radiation to cancer targets with precision.
How does the Cyberknife system work?
The Cyberknife uses a robotic arm to deliver radiation from multiple angles, ensuring accurate targeting of tumors while sparing healthy tissue.
What are fiducials?
Fiducials are small markers placed near cancer targets to help accurately locate them during radiation therapy.
What are the side effects of SBRT?
Possible side effects include skin irritation, fatigue, and in rare cases, damage to nearby organs.
Who is a candidate for SBRT?
Patients with persistent or recurrent gynecological cancers that are resistant to other treatments may be candidates for SBRT.
How is patient positioning ensured during treatment?
Advanced imaging systems track fiducials and adjust patient positioning to maintain accuracy during radiation delivery.
