Shad-o-Scan 3001/4501 X-Ray Detector
Teledyne DALSA
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.
