iCAT Calibration.
Sorry gang. I published the last without any text.
We are now recommending to calibrate your iCAT machines (click View/Calibrate - make sure nothing is in the field of view of the x-ray) twice a day instead of only once. The reason for this is that there are temperature fluctuations throughout the day and the extra calibration will help account for this and improve the quality of the scan. We also recommend that if you are doing high res. scans (0.2 voxels) that you calibrate just before that scan. Also, keep in mind to that calibrating is not meaningful if you do it at 8 am but don't take a scan until noon. In this case, wait until just before your first patient that day to calibrate. Let us know if any questions.

We still recommend 2 hours for the machine to warm up. Again, this has to do with the sensor.
