C0020002 — Reconstruction fails with a recon-process error (RTM REC)

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

What C0020002 means

The code originates in the RTM REC — recon-process stage section of the RTM REC (recon-process stage). Severity level A1 (Alarm — high severity).

Reported action: Try the reconstruction again from the stored raw data and check whether the same series fails a second time, then review the images before releasing the patient. Record the protocol and reconstruction mode and escalate to your service representative — the table carries no further detail for this code..

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.", graded A1 (high-severity alarm).
