Key Features

“4+1” 3D Spatial Design

4 layers of ionization chambers combined with 1 central line layout fully cover both high- and low-dose regions in 3D space, enabling precise, full-volume dose-distribution measurement.

Coplanar & Non-Coplanar Verification

Supports both coplanar and non-coplanar verification to meet diverse treatment-technique requirements and flexibly adapt to different clinical applications.

Multi-Target Verification

Overcomes the limitations of single-plane measurement. For multi-target SBRT, it effectively prevents missed-dose regions, improving the completeness and accuracy of verification.

No Angular Correction Required

The cylindrical ionization chambers naturally align with the gantry rotation, eliminating the need for additional detector angular-response correction, simplifying operation while maintaining data fidelity.
