Run the DCA offset data check (X-ray inhibit)
Put the Aquilion 16 into X-ray-inhibit test mode with the XC PWB's JP3 jumper, then run a DCA acquisition through Decode/Re-Correct/Calc(ScanData) to read the per-channel offset data used for DAS noise and offset-SD checks — without generating any actual X-rays.
Applies to
Aquilion 16 (TSX-101A) — data acquisition section volume 2D201-065, source p.73-75, item "(2) Offset data check" (the Figure 5.4-10/5.4-13/5.4-14 numbering places it within the volume's §5.4 sequence of DCA-based checks; no explicit "5.4.x" subsection number is printed on these pages themselves). A companion procedure in a different source volume (the DCA operating-software manual) documents the same JP3 test-mode workflow under its own section 2.4.2 — see Related, toshiba-ct-aquilion16-software-dca-test-offset.
Personnel
1 technician · Intermediate — physically move a jumper pin inside the SRU power supply unit (XC PWB) from one position to another, then drive the DCA application through a multi-step acquisition/decode/calculation workflow (Acq. Detail → scan conditions → Decode + Re-Correct → Calc(ScanData) with start/end channel entry); no board-level rework beyond the single jumper change (skill assessment derived from procedure content — not an OEM-stated skill level).
