X-ray Lithography

High-Aspect-Ratio Microfabrication

X-ray Anti-Scatter Grids - Creatv's patented cellular grid design, combined with proprietary fabrication methods, significantly increases transmission of the primary radiation while reducing scattered radiation, enhancing image contrast and readability.

Collimators - Creatv makes customized, high-resolution collimators for gamma-ray imaging in pinhole, parallel-hole, fan-beam and cone-beam formats.

Creatv's precision grids and collimators improve the clarity, resolution, and contrast of x-ray and nuclear imaging.
