CrystalBalls™: radiochromic polymer gel dosimeters, sealed inside thin-wall glass spheres of standardized dimensions, approximating the size of a human head. Self-developing. Muscle-tissue equivalent. Instant QA phantom setup. No Cables. No electronics. Readout by a desk-top laser CT scanner.
Specifications: isotropic voxel resolution down to (0.5mm)^3. Dosimetric accuracy: 0.5% relative, 2% absolute.
For QA of: SRS, SBRT, VMAT, MR-Linac, CyberKnife, GammaKnife, Proton Therapy. Good for commissioning, machine QA, and patient-specific QA.
QAbyMail ™ Service: Customers return exposed CrystalBalls and DICOM files to 3D Dosimetry Lab for laser CT scanning and QA analysis. High-definition 3D QA reports are returned by email. They may be customized but normally include 3D gamma histograms & passing rates; volume histograms and voxel statistics for dose difference and distance-to-agreement; overlays of planned vs measured 3D and 2D isodoses, profiles and dose-volume histograms; detected shifts of the center of mass of the 3D dose cloud; interactive 3D maps of dose difference, distance-to-agreement, and 3D gamma.
The Crystal Ball™ End-to-End QA detects and measures any and all clinically significant cumulative errors that may originate anywhere during radiation therapy or radiosurgery planning and delivery process and are located anywhere within the treated volume.
