Beamscan MR for ViewRay MRIdian and for Elekta Unity
December 23, 2019 — The Beamscan MR motorized 3-D water phantom provides a dedicated, fully equipped solution for beam data commissioning and annual QA of MR-Linacs. It is available for ViewRay MRIdian and Elekta Unity and is the first motorized 3-D water phantom suitable for clinical use in a 1.5 T MR environment. The Beamscan MR phantom comes ready to use on a single carriage and includes everything needed for operation.
The Starcheck Maxi MR flat-panel ionization chamber array provides comprehensive, time-saving MR-LINAC QA with a single device and outstanding accuracy. One shot delivers all relevant beam data at 3 mm spatial resolution for radiation fields up to 40 cm x 40 cm, eliminating the need to use a water phantom for routine QA measurements.
Both Beamscan MR and Starcheck Maxi MR fully integrate with PTW’s Track-it 2.0 web-based QA data management software for automated trending and reporting.
PTW is continuously developing innovative dosimetry solutions to deliver fast, precise measurements for complex radiation equipment and treatment plans. PTW delivers a full line of dosimetry solutions for acceptance testing, beam data commissioning, and machine- and patient-specific QA.
