Dectris EIGER 2 - Lines-ROI

8.2. Lines-ROI
The Lines-ROI
®
functionality is available in EIGER2 X and XE detectors with 1 module in height (500K, 1M-W,
2M-W). This feature allows to read out a user-dened area of the sensor equivalent to a selected number of
lines (pixel rows) counted along the y axis, extending over the full horizontal length of the detector. This can
be used to increase the acquisition frame rate with a reduced area selection.
In order to activate this modality, the roi_mode should be set to ”lines” via the API. The ROI area is congured via
the parameter roi_y_size, which denes the total number of pixel rows to be read out and should be a multiple
of two. The Lines-ROI is centred around the horizontal axis of the detector.
