ProcedureGantry — Optical / projectorSetup & CalibrationAdjust
Adjust the projectors (inner, median, external)
Align the Aquilion 16 gantry's inner, median, and external projectors (the gantry positioning-light lamps) against a water-phantom target so their light beam patterns land exactly where the couch top and scan plane expect them.

Aquilion 16 (TSX-101A) — Gantry mechanism, source volume 2D201-061
Personnel
1 technician · Intermediate — CT gantry optical-alignment work. The task calls for precise phantom setup (taping solder strips to specific reference lines), reading a scanogram image to confirm alignment, and iterative light-beam adjustment against printed patterns or couch-top reference marks, with a stated tolerance of 1 mm or less at one checkpoint. No torque value, electrical isolation, or power-down is called out in source for this task. (Skill-level assessment derived from procedure content — not an OEM-stated skill level.)
