Canon Medical (Toshiba) CT error code, reported by the COM-PRE (PRE data link).

What B6620000 means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 and Aquilion S16 and Asteion Super4 and Aquilion 16 CT systems, status code B6620000 indicates: Offset-data overflow on the COM-PRE path. The code originates in the COM-PRE — PRE / scan data transfer section of the COM-PRE (PRE data link). Severity level 1 (Information / dialog).

Reported action: Offset (zero-signal reference) data came back beyond the range the system accepts. Repeat the acquisition, and run the warm-up/calibration the system offers before scanning patients again. If the overflow persists, the offset acquisition and the front end feeding the PRE need to be checked by service..

Reported on Aquilion 16, Aquilion RX/V4-62R004, Aquilion ONE/V4.2, Aquilion S16, Asteion Super4 and V3.20R003. It comes from the 8:Device COM-PRE table, where the OEM text reads "Error ( offset data overflow )."
