Cranial SRS belongs to the family of RT Elements providing treatment planning for radiation therapy. Each RT Element is developed to support treatment planning for specific indications.
Cranial SRS provides single lesion planning using a Volumetric Modulated Arc Therapy (VMAT) optimization, thus allowing dose modulation with both the MLC leaf positions and the dose rate or gantry speed. It particularly offers planning for lesions in the brain that benefit from dose modulation like large tumors close to organs at risk with a complex geometry. These indications include, but are not limited to Vestibular Schwannomas, Pituitary Adenomas, Meningiomas and Gliomas. Cranial SRS can also be used for treating vascular anomalies like arteriovenous malformations (AVMs).
Cranial SRS can be accessed via two clinical workflows under specialty RT Planning:
