C0020005 — "Error in recon-process" alarm on the CT console (RTM REC)

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

What C0020005 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 C0020005 indicates: "Error in recon-process" alarm on the CT console (RTM REC). 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: Check the reconstructed images from the affected scan before releasing the patient — a failure in the recon-process can leave the image set incomplete. Note which protocol and reconstruction settings were in use, then call your service representative; the error table gives no more detail than the recon-process error itself..

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.
