CT Injector Arm and Mounting: Ceiling or Pedestal?

Pedestal CT injector: mobile and quick to install

A pedestal ct injector stands on a wheeled base. The ulrich medical CT motion pedestal unit measures 645 × 645 × 1,445 mm and weighs 79 kg, so it can be moved between positions or between rooms and needs no structural work in the ceiling. It also works as a portable contrast injector in the sense that it can be parked away from the table when not in use, although it is not a handheld device.

The trade-off is floor space and cable management. The base occupies part of the room next to the gantry or table, and power and communication cables cross the floor unless routed in ducts. In small rooms this can restrict access to the patient.

Check also the path from the storage area to the scan room: door widths, thresholds and floor finishes affect how easily a 79 kg unit can be moved, and the floor itself should be level and free of cable ducts that wheels could catch on.

Ceiling mounted CT injector: clear floor

A ceiling mounted ct injector hangs on a rail or column from the ceiling and keeps the floor clear. CT motion SPICY is available as a wireless pedestal unit or as a ceiling-mounted version with 1–3 arms, positioned by the manufacturer for small rooms. Several arms can carry the touch terminal, the injector head and the media containers at convenient heights.

A ceiling installation has to be planned with the building: the ceiling structure must carry the load, and rail position, arm reach and the swing range have to be checked against the gantry, lights, rails and other fixtures. This is a structural task for a qualified engineer and the installer, not something to improvise on the day.

• Floor stays clear for the table, trolleys and wheelchairs
• Arm reach and rotation can be matched to table positions
• Needs structural review and fixed positioning
• Cables can be concealed in the ceiling or arm

Room planning, arm reach and cable routing

Draw the scan room to scale before choosing. Mark the gantry, table travel, door swing, lead-glass window and the control-room cabling route. Check that the injector can reach the patient's arm in the positions used for cardiac, head-first and feet-first scans without stretching the patient line, and that the line is never trapped by the table.

For a pedestal unit, plan a parking position with a socket and a clear route that avoids tripping hazards. For a ceiling unit, plan where power and network cables run. If you are connecting to the scanner or PACS, include the interface cabling; see our scanner interface article.

How to choose

Choose a pedestal unit if the room is shared, if flexibility matters or if the ceiling cannot easily be modified. Choose ceiling mounting if floor space is tight, if staff need free access around the table or if you want a tidy installation with fewer trip hazards. Whichever you pick, discuss cleaning access, because arms and rails also need to be wiped down.

The right answer is often visible only on the drawing, so ask for a site survey. Compare the options as part of the overall model comparison for your workload.

Finally think about hygiene and cleaning. Ceiling arms, rails and cable entries should be reachable for wipe-down under your infection-control routine, and the pedestal base needs a floor that can be cleaned around the wheels.
