Shuttering
The Rad-icon Detector does not have a shuttering mechanism built into the detector. The
detector can be operated quite normally with a continuous beam x-ray source, however
there can be motion blur associated with continuous beam imaging. In the case that
pulsed x-ray operation is required, the X-ray pulse must be carefully timed so that x-ray
from the pulse are not incident on the detector during readout. This will cause imaging
artifacts that show up as very uneven illumination within the images.
Dark Current after Standby
A first image acquired after long time in standby mode might contain unwanted signal. It
is recommended to read and discard at least 2 images after standby.
Mode switches
A first image acquired after a change of mode might contain unwanted signal. It is
recommended to read and discard one or more images at the start of a new measurement
sequence.
When switching from free running to any other mode the detector may output still one
image because the timing sequence was already started.
