Phase Coherence Imaging
Assess with Certainty Using PCI
Eliminate doubt through phase coherence imaging's capacity to detect and accentuate historically difficult-to-detect flaws, including hook cracks and stress corrosion cracking (SCC). Use PCI to clearly distinguish individual flaws in colonies of fine cracks and characterize them with certainty.
- Hook Cracks & SCC: Detects flaws that traditional PA often misses.
- Colony Discrimination: Separates individual flaws in complex crack fields.
- Twin TFM/PCI: Run both simultaneously for maximum throughput.

Total Focusing Method
3× Faster TFM Acquisition Rate
Obtain crisp TFM imaging at up to three times faster acquisition rates compared to the previous generation, dramatically reducing inspection time without compromising image quality. The OmniScan X4's TFM delivers the most detailed view of material integrity available in a portable device.
- 3× Speed Gain: Dramatically reduce scan time on large components.
- Crisp Imaging: High-resolution reconstruction of the inspection zone.
- Proven to Perform: Trusted by NDT professionals worldwide.
