C0020004 — Recon-process message during CT reconstruction (RTM REC)

Canon Medical (Toshiba) CT error code, reported by the RTM REC (recon-process stage).

What C0020004 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 C0020004 indicates: Recon-process message during CT reconstruction (RTM REC). The code originates in the RTM REC — recon-process stage section of the RTM REC (recon-process stage). Severity level 1 (Information / dialog).

Reported action: Repeat the reconstruction from the stored raw data and verify the resulting images are complete before use. Because the table lists this code under both an information/dialog grading and a high-severity alarm grading, note exactly how it appeared on your system and pass that, with the scan and protocol details, to your service representative if it recurs..

Reported on Aquilion 16, Aquilion RX/V4-62R004, Aquilion ONE/V4.2, Aquilion S16, Asteion Super4 and V3.20R003. It comes from the 101:Device RTM REC group of the console error table, where the OEM text reads "Error in recon-process." The table lists this code with two gradings across the covered platforms — information/dialog and A1 high-severity alarm — so what appears on screen depends on the system.
