B8320000 — Respiratory-gating signal abnormal — respiratory sync signal error (5102)

Canon Medical (Toshiba) CT error code, reported by the SYNC device — respiratory gating.

What B8320000 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 B8320000 indicates: Respiratory-gating signal abnormal — respiratory sync signal error (5102). The code originates in the SYNC — respiratory gating section of the SYNC device — respiratory gating. Severity level A1 (Information / dialog).

Reported action: The signal is already bad before the scan is confirmed, so check the respiratory gating system and its connection as the message instructs: sensor/belt placement and tension on the patient, the sensor cable and its connector at the SYNC interface, and a visible respiratory waveform on the monitor. Re-seat the sensor and confirm a stable trace before pressing confirm; if the waveform is good and the code persists, follow the SYNC device checks in the service manual and call service..

Toshiba/Canon Aquilion RX (V4-62R004), V3.20R003, Aquilion ONE (V4.2), Aquilion S16, Asteion Super4 and Aquilion 16 CT systems, on the SYNC device that handles the respiratory-gating signal. The service table pairs this code with detail 5102: a respiratory sync signal error, with the gating signal already abnormal before the confirm button is pressed. The same short message text is also published under code B8F20000 (detail 5103).
