Our NDT Software Products
TWI Crystal™
Advanced ultrasonic inspection software for automated FMC, VSA and PWI acquisition and analysis
TWI Crystal™ is an advanced ultrasonic inspection package that enables automated Full-Matrix Capture (FMC), Virtual Source Aperture (VSA) and Plane Wave Imaging (PWI) inspection of industrial structures. Its intuitive interface gives engineers granular control over inspection parameters, delivering high defect detection and sizing accuracy in both in-service and production environments.
Key features:
- FMC, VSA and PWI support — advanced ultrasonic techniques with in-depth process parameters for high-fidelity imaging
- Multi-mode imaging — full control over pulse-echo, pitch-catch, self-tandem and surface wave inspection modes
- Complex geometry inspections — conformable wedges and adaptive-TFM algorithms for non-conventional surface profiles and through-weld-cap inspections
- Linear, Dual Linear and Dual Matrix Array Transducer support — flexible transducer configurations for a wide range of applications
- Real-time scanning and display — GPU-accelerated algorithms enable real-time processing, eliminating the need for post-processing
- Single or Dual Transducer configurations — supporting upstream/downstream weld inspections and pitch-catch capability
- High sizing accuracy — underpinned by experimental trials and rigorous statistical analysis studies
TWI Crystal™ is suitable for a broad range of industrial sectors including nuclear, defence, oil and gas, aerospace and rail, with custom software solutions, procedure development, inspection services and application-specific training available.
TWI Crystal™ SDK
A flexible software development kit for custom NDT system integration
The TWI Crystal™ Software Development Kit (SDK) provides a general purpose, flexible software architecture to control and interact with a wide range of sensors, robotics and hardware control systems — with access to the most advanced NDT inspection algorithms and a GUI for data interpretation and analysis.
The SDK is structured around three abstraction layers — User Interface, Data and Acquisition — enabling developers to engage at whichever level suits their application, from full custom UI builds down to raw acquisition control.
Key features:
- Three-layer architecture — UI, Data and Acquisition layers for maximum development flexibility
- Access to advanced NDT algorithms — the same inspection algorithms underpinning TWI Crystal™
- Friendly GUI — built-in interface for data interpretation and analysis
- Broad hardware compatibility — supports a wide range of sensors, robotic systems and hardware controllers
- Proven technology foundation — built on the same platform as TWI Crystal™
- Free 90-day trial — available on application for qualifying organisations
- Backed by TWI's agile development team — ongoing support for custom integrations and bespoke deployments
The SDK gives developers and engineers the flexibility to create unique, application-specific inspection systems without starting from scratch, backed by TWI's deep expertise in NDT research and development.
