ThorX Webinar: Your SBRT QA Game-Changer

Learn how to transform your SBRT QA process with LUCY ThorX Phantom—the all-in-one solution for simulation, planning, imaging, and delivery QA. Discover how its realistic evaluation capabilities and unmatched versatility can save you time while elevating your QA standards.

Comprehensive Evaluation

Simulation, Treatment Planning, Imaging, and Delivery QA as recommended by TG-53, TG-66, TG-142 and AAPM MPPG guidelines.

Integrated Testing

4 primary modules that are assembled using rods, of a density similar to trabecular bone, around the periphery. Various internal structures and test objects as well as external engravings and fiducials are utilized for integrated testing.

Pseudo-Anthropomorphic Anatomy

Ribs, Vertebrae, Spinal Cord, Lung, and Kidney.

Dose Verification

Measure dose with ion chambers and film. Four detector cavities and targets for Multiple Met SBRT QA.
