What is Tomography?
Tomography is a mathematical procedure that is applied to Crosshole Sonic Logging (CSL) data, providing the user with a visual image of a shaft’s internal defects. The procedure involves solving a system of equations based on First Arrival Times (FAT) in order to calculate wave speeds at various points within the shaft. Tomography wave speeds distributed throughout the shaft are directly proportional to density, indicating concrete quality. PDI-TOMO is an extension of the CHA-W software designed for superior tomographic results from CHAMP-XV data with increased efficiency for the user.
Benefits of Tomography Analysis:
• Provides a more precise location and shape of a defect detected through CSL data
• Generates easily comprehensible and professional outputs of the engineering analysis
• Offers an intuitive visual identification of the damaged areas
• Provides a valuable add-on service for the testing engineer
PDI-TOMO Features:
• Accurate 2D and 3D results
• Works with current Windows Operating Systems (WIN 7+)
• Seamless one-step operation from CHA-W export
• Significant reduction in analysis runtime, greatly improving productivity
• Smart user selection of “good” or “poor” concrete wave speeds
• Easily selectable wave speed limits to match typical CSL evaluation criteria
• Selection available in terms of percent reduction of average wave speed or absolute wave speed values
• Automatic critical slice detection
• User selectable number of slices for output reporting (1 through 4)
• Effective area vs depth plot for easy evaluation of critical sections
• Customizable and professional output report to fit the needs of each user
• Enhanced export options in updated CHA-W software for accurate tomographic results
Minimum Requirements:
• CHA-W version 2016.017
• Windows 7
• Graphics card and driver supporting OpenGL 3.3.0
