In 2018, we introduced the SRS MapCHECK® — a first-of-its-kind high density array, purpose-built for high dose, small volume stereotactic procedures.
Since release, we've seen rapid and widespread adoption. Thanks to users worldwide, the device now stands as the most widely used patient-specific QA array for SRS/SBRT deliveries.
With detector spacing informed by the Nyquist-Shannon theorem, the SRS MapCHECK has been proven in many studies to deliver film-quality results without the film.
A film-less technique cuts process time significantly, removing an obstacle to SRS/SBRT adoption — and enabling re-investment of physicist time back into patient care.
Stay tuned for more on the SRS MapCHECK. We have some exciting news to share soon. In the meantime, we invite you to learn more here.
RECAP: AAPM ABSTRACTS FEATURING SRS MapCHECK
At the recent AAPM meeting, a number of abstracts featured SRS MapCHECK, including the following which focus on use of SRS MapCHECK with an Elekta Versa HD and a CyberKnife.
TH-205-372-2
Quality Assurance Validation of Exactrac-Guided Brainlab Cone-Based Functional and Multileaf Collimator-Based Multimet Elements Stereotactic Radiosurgery on an Elekta Versa HD Platform
Joseph P. Dugas, PhD, et al., Willis-Knighton Cancer Center, Shreveport, LA
| Conclusion: “Submillimeter accuracy is achievable for both MLC-based and cone-based single-target SRS. For targets off-axis by 5cm or more, larger margins are warranted. Clinically, 1.5mm margins are used for such lesions. In all cases, patient specific QA demonstrates acceptable treatment accuracy." |
PO-GePV-T-422
Cyberknife Precision IMRT QA Comparison between Myqa SRS Phantom and SRS Mapcheck
Wenzheng Feng, MS, Hackensack Meridian Health, Neptune, NJ, Jing Feng, MS, Philadelphia Cyberknife, Philadelphia, PA and Jun Yang, PhD, Radiation Physics Solutions, Philadelphia
| Conclusion: “The recommended target size criteria is: PTV<4~5cm for SRS MapCHECK and PTV>3~4cm for myQA SRS phantom." |
