Ceiling-Suspended Gantry

Motorized ceiling-mounted C-arm that positions the tube + detector around the patient. Geometry calibration drifts over time — the #1 under-diagnosed issue on high-volume Alluras.

Fits

All Allura Xper variants (biplane has two gantries).

Field notes

Geometry calibration annually minimum, biannually in high-volume rooms. See field-guide/philips-allura-xper.
