How to open
This function is opened from the Display menu.
Description
The Expansion function allows you to compensate when the number of samples is below the number of pixels. You may experience that the presentation you are looking at have a larger resolution than the number of samples required to
fill it. This may be the case if you for example zoom in the echoes. You are then permitted to choose if the ME70system shall interpolate the existing data to ‘smoothen’ the presentation, or copy sample values into the empty pixels.
NoteNote that the Expansion setting can also be adjusted in the Echogram dialog box.
Details
Interpolation
To adjust the presentation, the pixel values are interpolated between two sample values.
Copy
The expansion takes place by copying sample values into multiple pixel values.
