Exploit its versatile PA, faster TFM, innovative PCI, and efficient twin TFM/PCI to perform rapid and reliable inspections of welds and components.
Be Ready for What’s Next: OmniScan X4 Flaw Detector
A portable yet powerful solution, the speed and versatility of the OmniScan™ X4 multitechnology series boosts your productivity while increasing confidence in your assessments. Exploit its advanced phased array capabilities, efficient total focusing method (TFM), and innovative phase coherence imaging (PCI) to detect and interpret challenging flaws and secure the integrity of your assets by identifying damage earlier.
Proven to Perform, Trusted to Deliver
Each OmniScan X4 unit is a complete multitechnology inspection toolbox, enabling you to exploit multiple ultrasonic testing techniques. Leverage its detection and measurement capabilities to accurately identify and evaluate the severity of damage before it becomes critical, protecting welds, components, and assets most susceptible to cracking or corrosion.
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.
3x Faster TFM Acquisition Rate
Obtain crisp TFM imaging at up to three times faster* acquisition rates than the predecessor model (X3 64) thanks to the OmniScan X4 series’ improved processing power. Exploit the increased speed and 128-element capacity of the OmniScan X4 64:128PR unit to perform TFM inspections with extended focusing capabilities.
*Achieving this speed depends on the configuration and the use of sparse firing. Inquire for more details.
Gain Instant Insights and Eliminate Inefficiency
Twice the Confidence with Twin TFM and PCI
Exploit the individual attributes of PCI and TFM to thoroughly investigate the volume of welds from both sides simultaneously. Use two probes to scan the weld in one pass, displaying TFM and PCI results to compare, measure, and confirm your characterization of indications with efficiency and precision.
Engineered for Speed and Simplicity
Performing phased array, TOFD, TFM, and PCI is straightforward and intuitive on the OmniScan X4 series. Inspectors of any experience level can exploit these techniques with increased efficiency and more confidence utilizing the simple step-by-step scan plan and application presets.
Convenient Application Presets
Improve the learning curve and increase the reliability and consistency of inspections between operators with the OmniScan X4 application presets. Even low-level users and new users can produce an optimal PA or PCI configuration within minutes.
With options for corrosion and composite inspections, these preprogrammed parameters simplify scanning setups using HydroFORM™, FlexoFORM™, and RollerFORM™ scanners, and you can adjust the settings as needed.
Ease Complex Configurations
The OmniScan X4 scan plan’s intuitive step-by-step 3D graphics ease your inspection setups, from the most basic to the most complex.
When setting up your raster scan plan, the scan axes can be customed named and you can create a datum reference point relative to the asset. These real-world references as well as the true orientation correction, greatly ease the creation of an intuitive schematic representation of the inspection data for your report.
Applications
Choose the Right Model for Your Application
Each model of the OmniScan X4 series has the capability to drive probes with a certain number of elements, offering varying focusing capabilities for different materials and thicknesses. Here is an overview of the types of applications that the four models are most proficient at performing. Contact us or your Evident representative for more details.

HTHA Inspection Solutions
OmniScan™ X4 Phased Array Flaw Detector with TFM and PCI
Detect and Define Smaller HTHA Cracks
Detecting HTHA early and reliably is so challenging that multiple inspection methods are often used in conjunction to maximize the probability of detection. Time-of-flight diffraction (TOFD), along with focused phased array (PA) and the total focusing method (TFM), especially using Dual Linear Array™ (DLA) probes, have shown to be particularly effective inspection techniques for this application.
OmniScan™ X4 flaw detector fully supports these methods, as well as innovative phase coherence imaging (PCI), which enhances small flaws and crack tips. OmniScan X4 instruments also offer a variety of onboard software tools to ease your setup and analysis workflow.
- Integrated DLA probe configuration and scanner configuration
- High-resolution TFM images (up to 1024 × 1024 points)
- Software tools to optimize the TFM inspection process, from setup to analysis (scan plan with AIM model, automatic TCG, sparse firing, soft gain and palette slider, live TFM envelope and image filters, gates, and alarms)
- 64-element TFM aperture and 128-element extended TFM aperture (OmniScan X4 64:128PR model)
- Phase coherence imaging to enhance small defects and crack tips (all OmniScan X4 units)
- Acquire up to 8 TOFD and phased array groups simultaneously for efficient screening
- Acquire and display up to 4 TFM and PCI groups at once
- Plane wave imaging (PWI) available with TFM and PCI (using the OmniScan X4 unit with linear array probes)
