Panels in main figure¶

Main figure¶

This figure is opened if you call InterSAFT. It contains different sections which we call panels. The panels are grouped around the main axis which displayes the calculation results or the preprocessed A-scans.

Aperture selection¶

Above the main axis you can find a panel for selecting a range of A-scans from one slice of the data. You can observe how the selection of the data influences the imaging result interactively and how the other imaging parameters influences the processing of one or more A-scans. The panel was originally designed for impulse echo data and it is less important for linear array data because the linear array data are not arranged in a way that the number of an A-scan corresponds immediately with the x-coordinate. (See: Aperture Window)
