Adjust the gantry positioning projectors (side, slant, and median)

Align the Activion16's rotation-section positioning projectors — the side, slant, and median-line units — so the light lines they cast match the reference marks used for patient and scan-plane setup. The procedure has two parts, done in order: first the side and slant projectors (§1.5.4.1), then the median projector (§1.5.4.2).

Applies to
Activion16 (TSX-031A). No model- or revision-specific restriction is stated in source; applies to the gantry's side, slant, and median-line rotation-section positioning projectors.

Safety

WARNING

Hazard: System laser beam device (rotation-section positioning projectors — the same side, slant, and median-line projectors adjusted in this procedure)

Consequence: Eye injury

Avoidance: Do not look directly into the projector's laser beam while it is ON and being aligned
