The present work refers to the
identification and analysis of modern needs both in the
industrial and the laboratory environment in applications with
the use of automated ultrasonic scanning systems for recording
and displaying thickness profiles (B-Scan) and the complete
mapping (C-Scan) of specimens and structures. A review of
modern system capabilities is presented with emphasis on the
increased needs for data recording and analysis through
specialized software that are capable of handling the volume
and complexity of the data produced by such systems. The
advantages provided by relevant software packages for the
analysis and presentation of ultrasonic scan data along with
their effectiveness are discussed. Thickness measurement data
handling techniques are investigated, including relevant/non-relevant
indication discrimination, waveform usage in analysis and
specialized display techniques. C-Scan composition techniques
to display complex geometries (Composite Area C-Scan) are also
investigated. Examples from industry and laboratory are
discussed where extensive use is made of software based
analysis and display of ultrasonic thickness data and the
relative advantages are discussed for the specific
applications.
