Benchmarking Tests of Contemporary SRS Platforms: Have Technological Developments Resulted in Improved Treatment Plan Quality?

Purpose: Stereotactic radiosurgery treatment delivery can be performed with a range of devices, each of which have evolved over recent years. We sought to evaluate the differences in performance of contemporary stereotactic radiosurgery platforms and also to compare them with earlier platform iterations from a previous benchmarking study.

Methods And Materials: The following platforms were selected as "state of the art" in 2022: Gamma Knife Icon (GK), CyberKnife S7 (CK), Brainlab Elements (Elekta VersaHD and Varian TrueBeam), Varian Edge with HyperArc (HA), and Zap-X.

Stereotactic radiosurgery and hypofractionated stereotactic radiotherapy for management of vestibular schwannomas: initial experience with 17 cases.

Background: Nowadays radiation treatment of patients with vestibular schwannomas (VSs) applied either as stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) represents a real alternative to surgical tumor resection.

Methods: During 2010-2011, 17 consecutive patients (19-75 years old) with a VS underwent treatment with SRS or SRT in our center. Microsurgery was initially offered in all cases but was declined for various reasons.
