August 2, 2013 (Norfolk, Va.) CIRS will introduce the Stereotactic End-to-End Verification Phantom (STEEV™) at the 55th Annual AAPM Meeting & Exhibition on August 4-8 in Indianapolis.
STEEV is a QA tool for evaluating stereotactic radiosurgery (SRS) system performance during commissioning and daily systems checks. To facilitate patient QA, STEEV serves as a surrogate patient to assess every step of the treatment process- from immobilization and multi-modality imaging (CT, MRI, PET) to thorough treatment plan verification. STEEV’s anthropomorphic, tissue-equivalent design makes it the only phantom to account for the challenging effects of tissue heterogeneity.
SRS is a non-invasive procedure that focuses high doses of radiation to destroy tumor volumes in small areas of the body. The procedure necessitates a high degree of accuracy in target localization and dose delivery, because small errors can result in significant under treatment of portions of the tumor volume or overdose of nearby healthy tissues. By providing challenging system checks, STEEV helps to identify system errors and ultimately leads to better patient outcomes- a key component to CIRS’ company values.
The introduction of STEEV compliments CIRS’ existing suite of site-specific end-to-end QA phantoms, including the Dynamic Thorax Phantom, Dynamic Pelvis Phantom and SBRT Thorax Phantom.
