High cooling keeps the ghost image trapped for longer. Either try not to image a bright object just before an imaging run or warm it up and recool. It will eventually fade over more images.
Some sensors are more prone to it than others. I have only seen it on my 16803 chip twice and it was minor on both times.
FLI has an RBI annihilator which consists of an IR flush several times of programmable length before you take an image. The downside is it increases noise as that flush bleeds out slowly during the subsequent image. I think you have to take darks using the flush as well to match at a temp. So I have never used that feature and have not noticed any problem. Its more for the now unpopular KAF09000 chip which has it bad. I believe the KAF6303 has this problem as well at times. KAI series chips work differently and do not suffer from this effect. Its only KAF series sensors. Not sure how Sony sensors fare with this. I have only heard of it connected with Kodak chips.
High cooling here is an advantage as it reduces the rate of bleed from the flush during the subsequent light exposure.
As far as for your SBIG simply be aware of it and don't image something bright before an imaging run and do darks on a freshly started up camera not one after an imaging run which may still have ghost images in it.
