SCT 4800 TF trouble : data AQ error
November 18, 2004 10:03
I can do the CR scan properly but during normal scan (rotation mode) I got at the end : DATA AQ ERROR ! then system go to Ready mode and no image is displayed.
Any suggestion is strongly appreciated.

Alessandro,
Your problem is related to rotational das pulses from the gantry. You need to check the encoder and also the input signal to the das trigger.
You can reach me at scanner1@eim.ae

most probably it is due to your rotational ckty.
it could be your encoder, or a rusty switch on drum. you can diagnose the defective switch it by rotating the gantry with local control box.
u can contact me on iftekhar786@hotmail.com

hello:
if the CR image is ok, the QV boards are ok, and detector too.
i think that you must run the software for check data acquisition under rotation, to see how send info into movement.
the das cable would be broken (some lines), or encoder could be bad too.
regards,
carlos
