What should a field engineer do about C0020003?

Confirm that the series produced by the affected exam reconstructed completely before the study is read, and note whether the alarm is tied to one reconstruction mode or appears on any recon. This is a high-severity alarm, so pass the details to your service representative rather than working around it.. Isolate the RTM REC — recon-process stage subsystem and follow the status-code troubleshooting in the service manual. FSELIB documents the full diagnosis and remedy for the Aquilion RX / V4-62R004 / V3.20R003 / Aquilion ONE / V4.2 / Aquilion S16 / Asteion Super4 / Aquilion 16.

C0020003 — High-severity recon-process alarm during CT reconstruction

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

What C0020003 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 C0020003 indicates: High-severity recon-process alarm during CT reconstruction. 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: Confirm that the series produced by the affected exam reconstructed completely before the study is read, and note whether the alarm is tied to one reconstruction mode or appears on any recon. This is a high-severity alarm, so pass the details to your service representative rather than working around it..

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). RTM is the real time manager on the CT console; REC is the reconstruction stage that turns the stored raw data into images.
