Convergent Bragg Lens

Proprietary radiation delivery technology

The Convergent Bragg Lens generates a therapeutic radiation beam from a kilovoltage (kV) source, enabling dose deposition at depth while minimizing skin exposure. This approach produces dose characteristics comparable to proton delivery systems that leverage the Bragg Peak, but with the potential for significantly lower infrastructure complexity and cost.

This capability we call the Convergent MiniBeam expands the applicability of SFRT to medium and small tumors while providing researchers with a powerful tool to evaluate immunotherapy compounds across emerging disease cell types.

Importantly, the technology may help convert immunologically “cold” tumors into more responsive phenotypes, positioning SFRT as a potential neoadjuvant strategy to enhance the effectiveness of immunotherapy.
