Interface OverviewLayouts are a fundamental element of TomoView. They allow you to view data in different representations. TomoView is available with predefined layout files. However, you can go further by creating your own layout that can be easily modified, saved, and loaded for rapid retrieval during inspection or analysis. The individual views can be customized through contextual menus (right-clicking their title bar) for more flexibility.

In addition to generic graphical features such as measurement cur-sors, zooming, and color-palette modifications, TomoView provides powerful tools available at the click of a button. Such tools fill different needs, depending on the inspection you are performing. Examples of the tools are: Fast Fourier Transform (FFT), Signal-to-Noise Ratio (SNR) Analysis Utility, PA Calibration, UT Settings, and Mechanical Settings.

OverviewTomoView™ is a PC-based software used for data acquisition and the visualization of ultrasonic signals. The configuration of ultrasonic parameters is flexible and different types of views can be displayed, ensuring it can be used in a large variety of applica-tions from industrial to research. TomoView is designed to per-form ultrasonic testing (UT) data acquisition with several Olympus phased array (PA) or conventional UT units.

Compatible with Microsoft Windows, XP, Windows Vista, and Windows 7, TomoView can run efficiently on standard laptop computers as well as on high-end desktop workstations, and it is capable of handling large data files (up to 1 GB).

Furthermore, its ability to read OmniScan® data files (.oud, .opd)and its user-friendly reporting capabilities, make TomoView an ideal tool for interpreting OmniScan data.

The TomoView Manager is arguably TomoView’s most use-ful component. It is used to add, remove, or modify groups, switch between different groups and gates, access UT settings, and set up mechanical parameters. In addition, it is used to change view display properties. It also provides an interface that easily changes the global gain, as well as the A-scan and gate parameters.

Advanced CalculatorThe TomoView™ Advanced Calculator is an essential and power-ful component of the TomoView software package. This calculator precisely programs angle beams and focal points.

Parameter entry is easy because the wedge, probe, and material data are already preprogrammed in the database. In addition, the graphical display of the resulting beams and angle beams provides you with an important validation tool.

Features include:

• 3-D ray tracing• Sectorial, linear, and depth scans• Dynamic depth focusing (DDF)• Focusing on user-defined lines• Ability to save results in OmniScan® usable format (.law)• Probe, wedge, and part database for easy definition of all

relevant parameters• Elementary A-scan generationFor each beam, near-field depth and angular deflection values are computed. You can therefore verify if appropriate focusing is possible.

TomoView™ is designed to perform UT parameter setups and data acquisitions with most Olympus conventional and phased array UT systems.

• Multigroup operation• Weld and part overlay (predefined weld bevel or CAD

drawings [.dxf])• Firing sequencer (beam interleaving firing scheme that

eliminates “ghost echoes” when a high inspection speed is required)

• Various types of inspection sequences: 1-D, 1.5-D, or 2-D based on encoder inputs, internal clock, or external PACE signal

• Editable compression factor (rather than specifying fixed number of samples to be recorded)

• DDF dynamically changes beam forming on reception for increased resolution (see results on page 4).

• Simultaneously calibrates all beams in a group for sensitivity, time-corrected gain (TCG), and wedge delay with the PA Calibration tool.

• Computed DGS curves for conventional UT probes (dual probes, angle probes,and contact probes) as well as certain specific PA probes from Olympus. The DGS curves allow you to size indications based on amplitude only (as seen on top image below). Corresponding TCG curves can easily be generated from DGS curves (as seen on bottom image below). TCG curves can then be edited manually.

Setup and Data Acquisition

Customizable Reference TablesProbe and wedge drop-down list boxes are used to quickly configure the beams. In addition, the probe and wedge reference tables can be edited and user-defined in order to add additional probes and wedges.

Programming TomoViewThe Advanced Calculator can be used as a standalone software but the results can be later imported into TomoView, allowing you to work on your inspection technique with no instrument con-nected.

Acoustic Field Simulation ModuleThe Acoustic Field Simulation Module is available as an op-tion in the Advanced Calculator. It is used to simulate spatially diffracted fields in 2-D or 3-D. This component is particularly useful when defining new inspection techniques.

• Validate settings• Measure beam width• Display LW and SW• Simulate focused probes• Support linear and conventional UT probes


OmniScan® Data AnalysisTomoView™ is the perfect companion for the OmniScan family of instruments. Seamlessly import OmniScan files for advanced processing and analysis in TomoView.

• Import OmniScan® data files and display volume-corrected views as well as multiple B-scan views.

• Correct potential operator errors in acquisition parameters (incorrect skew, index offsets, etc.) by reading back raw acquisition data without altering original data.

• Import and merge several OmniScan data files. For simplified interpretation, merge several groups into one.

Time-of-flight C-scan with echodynamic curves showing minimal depth between cursors

Easily add defects into the indication-table database.

When spatial overlap occurs, the maximum amplitude is conserved. The merged view therefore shows all detected indications, no matter what the original indication orientation was. Note that the indicators can differ because of the merge resolution used.

Data AnalysisVarious graphical tools are available for optimizing visualization and for retrieving numerical information from data.

• Standard tools, such as Crosshair cursors, Zoom with the possibility to link views, Gain Information and Software Gain, 3-D Cursor, and Color Palette compression and edition, are available.

• Zone tool (pink box), to mark and obtain numerical information from indications (amplitude, position, width, and length with –6 dB drop, etc.)

• Probe beam and scanner parameters that are editable in Analysis mode to account for operator error during acquisition (no rescanning necessary)

• Template layout displays that provide different ways to view data

• Switch between up to 10 user-defined layouts that can be created, modified, and saved to view data in many different representations. These layouts save view types, units, weld overlays, color palettes, software gain settings, information fields in various views, etc. Display amplitude and time-of-flight C-scans using different color palettes.

• Information groups (readings)—various parameters related to a data group and/or a specific view. Available information includes cursor positions, statistical calculations, probe settings, UT settings, file history, FFT, cylindrical calculation tools, etc.

• Echodynamic curves based on minimal position or minimal/maximum amplitude

• Processed data is saved in a companion file (.A01). Raw data integrity is never compromised.

• Screen capture tools• Export A-scan and C-scan data to .txt files

Advanced Analysis Tools• Multiple files can be opened and visualized in a single

instance with TomoView.• The Data-File Merge tool merges multiple files with various

groups and/or beams into one single file.

• Hysteresis Correction eliminates the visible backlash in 2-D scanning (in conventional UT).

• The Volumetric Merge tool merges various acoustic beams.• The TOFD Manager performs TOFD calibration, lateral wave

straightening, lateral wave removal, and synthetic aperture focusing technique (SAFT).

• Off-line gates (A, B,…) and Software C-scan module use the acquired A-scans to modify or create acquired C-scans. (Original data is never lost.)

• C-Scan Merge — merges interleaved C-scans based on minimum or maximum amplitude, or TOF.

• Off-line resynchronization of A-scans based on interface signal• Signal-to-noise ratio (SNR) — On a C-scan, this tool calculates

and displays areas for which signal-to-noise ratio is higher and/or lower than a certain threshold. Reference area is selected with the Zone tool (pink cursor).

Reporting• Creating a report in TomoView™ has never been easier. Use

the Zone tool to add an indication. Select your preferred indication table template (easily customized with additional readings and comments). Click add. Repeat for all relevant indications.

• Changing company logos and adding inspection specific information (operator’s name, site, part, etc.) can also be done very easily, so that a full html report including all relevant inspection settings, can be created in a matter of seconds.

• Once completed, indication tables are automatically saved in an .R01 file format, to be later uploaded into TomoView.

Related Software OptionsNDT REMOTE CONTROL LIBRARYThe NDT Remote Control library is a software development kit, which allows you to develop a special user interface for automated inspections using Olympus NDT instruments (phased array or conventional UT). From an external computer, the library can be used to directly control some functions of the TomoView™ software, offering a wide range of possibilities (Start inspection, Save data file, Reset encoder, etc.).

NDT DATA FILE ACCESS LIBRARYThe Data File Access library is a software development kit, which allows you to read data files using a custom application. It is suit-able for software engineers or researchers who need to develop special software in order to visualize, process, or create reports from data acquired using Olympus instruments.

The Data File Access library provides high-level access to data that normally prevents users from dealing with the complex architecture of the data files. Data and all the parameters related to the data interpretation can be easily read (refracted beam angles, velocity, delays, offset, etc.).

Both libraries are based on a COM interface, which allows you to perform related functions from different software environments (Microsoft Visual C++, Microsoft Visual Basic, LabVIEW, C#).
