1 SRS MapCHECK SRS Patient QA, No Film Your Most Valuable QA and Dosimetry Tools
2 SRS Patient QA, No Film As clinics strive to treat with the smallest field possible, the demand for SRS/SBRT QA grows as well. We ve developed our tools to provide accurate, independent QA while saving you time. The SRS MapCHECK does this by replacing film for your small-field dosimetry. 1 I 2 SUN NUCLEAR CORPORATION // sunnuclear.com
3 Have Confidence in your Stereotactic End-to-end Testing SRS MapCHECK is the latest QA solution to address the growing demand for stereotactic QA. The SRS MapCHECK can take the place of film for small-field dosimetry, in support of patient-specific QA. It was designed to insert into the StereoPHAN, Sun Nuclear s solution for stereotactic commissioning and end-to-end testing. These simple and powerful tools ease testing in all parts of the process. INTRODUCING SunPoint 2 Diode Detectors Smallest diode available Increased small field accuracy Patient Plan QA SNC Patient software allows rapid analysis of QA measurements against plan. SUN NUCLEAR CORPORATION // sunnuclear.com 3
4 SRS MapCHECK and StereoPHAN Designed to Work Together SRS MapCHECK Complements Stereotactic Workflow for Small Field Dosimetry Additional Inserts 152 mm Cylinder 360 Rotation Precision Leveling SRS MapCHECK Features and Benefits 2D array for SRS applications 1,013 SunPoint 2 Diodes, providing high resolution 2.47mm detector grid Replaces film for patient-specific QA, expediting the workflow for time-sensitive patient QA Provides relative dose in a single measurement Works with static, rotational, non-coplanar, FFF, cone and MLC fields 1 6MV and 10MV When used with StereoPHAN, supports irradiation from any gantry angle No Angular dependence Integration Designed to insert into the StereoPHAN Runs on SNC Patient software 1 Couch Angles up to 45 o are supported 4 1 I SUN NUCLEAR CORPORATION // sunnuclear.com
5 SNC Patient Software Simply import the QA files from your treatment planning system (TPS) and SNC Patient software compares the dose distribution of the treatment plan file to the actual measured values. Highlights No Angular dependence corrections required Detects and corrects for translational offset between compared datasets with precision of 0.1mm for SRS applications Uses Gamma Analysis 2 with passing rates greater that 90% using 3% and 1mm, global, as compared to True Dose 3 Easy to deliver and analyze High spatial resolution Able to compare dose-to-dose with gantry and couch geometries included Ability to measure dose in coronal plane at any gantry angle Instantaneous analysis / no film scanning 2 Ju, T., Simpson, T., Deasy, J. O., & Low, D. a. (2008). Geometric interpretation of the dose distribution comparison technique: Interpolation-free calculation. Medical Physics, 35(3), True Dose- determined from film measurements, calculations from commissioned treatment planning systems or other means acceptable in clinical practice SUN NUCLEAR CORPORATION // sunnuclear.com 5
