Thank you Ben and Jotsna for your responses.
It seems that we have an issue that neither one of you is experiencing. When we take a CBCT, the issue is not that we occassionally get blips in the RTDs: the cameras are unable to see the patient at all during the entire acquisition (not sufficient surface detected) so there are no RTDs to monitor. Between the gantry, the XVI panel and source, and the hexapod frame, the entire FOV is blocked. Do you have recommendations for where to place the hexapod frame or do you remove the frame during the acquisition?
Thank you,
