Acquire calibration data (NRA / air calibration)

Open the Aquilion 16's calibration data acquisition function from the console scan monitor — a three-click menu path that hands off to the full NRA/air-calibration workflow documented in the software volume — after waiting out the 3-hour detector warm-up that gates it.

Applies to
Aquilion 16 (TSX-101A) — data acquisition section volume 2D201-065, subsection 6.2.3 "Calibration data acquisition (NRA/air calibration)" (source, p.96). This is the third of the chapter's four repair subsections — 6.2.1 DAS PWB replacement (p.87-88), 6.2.2 main detector replacement (p.89-95), this calibration step, and 6.2.4 REF detector replacement (p.97-99) — and is the step the main detector replacement flowchart itself lists last, as "Acquire calibration data," immediately before "End" (source, p.89; see toshiba-ct-aquilion16-das-replace-main-detector, Related).
Personnel
1 technician · Basic — three menu selections at the console scan monitor ([Utility] → [Maintenance] → [Calibration data acquisition]) to open the function. The acquisition workflow that follows (NRA phantom scans, air calibration, FOV sequencing) is Intermediate skill and lives in a separate volume — source itself defers there rather than describing it in this subsection (skill assessment derived from procedure content — not an OEM-stated skill level).

Safety

NOTICE

Hazard: Starting calibration data acquisition before the main detector's temperature has stabilized after system power-on.

Consequence: Detector temperature stabilization normally takes 2 to 3 hours (varies with room temperature); calibration data acquired before it stabilizes is not reliable.

Avoidance: Wait at least 3 hours after system power is turned ON before starting calibration data acquisition.
