Canon Medical (Toshiba) CT error code, reported by the RTM — pre-process / reconstruction control (ELCTL).

What C0900006 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 C0900006 indicates: No response to ROI setup during reconstruction. The code originates in the RTM — ELCTL (pre-process / recon control) section of the RTM — pre-process / reconstruction control (ELCTL). Severity level A0 (Alarm).

Reported action: The ROI (region of interest) setup command went unanswered during reconstruction. Check the reconstruction path (the MHR boards in the REC BOX) for a communication fault: review the event log, confirm the MHR boards are running, and retry the reconstruction with the same ROI setting to see whether the fault is reproducible..

Toshiba/Canon Aquilion RX (V4-62R004), V3.20R003, Aquilion ONE (V4.2), Aquilion S16, Asteion Super4 and Aquilion 16 CT systems, reported under the RTM (real time manager) ELCTL device group of the system error message table. Reconstruction is performed by the MHR boards of the data processing unit in the REC BOX.
