Immobilization with trUpoint ARCH is accomplished using multiple components - a custom head support, bite tray, thermoplastic mask and nasion cushion - allowing a truly custom hold for superior results. Each of these components are designed specifically for SRS patient immobilization and each trUpoint ARCH setup is specific to the individual patient, ensuring excellend reproducibility from fraction to fraction.
- Proven to allow less than 1 mm of patient movement during intrafraction immoblization testing (based on the 90% confidence intervals of the vertical, longitudinal and lateral mean intrafraction values)
- Frameless arch design provides a secure hold with no surgical attachment to the patient
- Interfraction patient positioning tests show equivalency to high-priced competitive systems
- When used with CIVCO's Universal Couchtop™, setups are dosimetrically matched from simulation to treatment
