Siemens Cios Spin

Family: Siemens Cios · Modality: C-Arm Mobile Fluoroscopy

Siemens Healthineers' mobile 3D C-arm — extends the Cios platform with cone-beam CT acquisition capability for intraoperative 3D imaging in orthopedic, trauma, and spine surgery. Sibling to the Cios Alpha (premium 2D), Cios Fusion (mid-tier), and Cios Select (entry). Direct competitor to Ziehm Vision RFD 3D and the Medtronic O-arm in the intraoperative-3D-imaging segment, and increasingly to dedicated intraoperative CBCT platforms like Brainlab Loop-X.

The 3D mobile C-arm category sits at the intersection of conventional fluoroscopy (where the C-arm has been a workhorse for decades) and modern intraoperative-CT / intraoperative-CBCT (where dedicated platforms like Loop-X and the O-arm define the high end). Cios Spin's positioning is "C-arm with optional 3D" — most clinical use is conventional 2D fluoroscopy, with the 3D acquisition reserved for confirmatory imaging at decision points (pedicle-screw placement, fracture-reduction confirmation, arthroplasty alignment).

Distinctive technology

  • 2D + 3D in one mobile chassis — same C-arm geometry as Cios Alpha for routine 2D fluoroscopy; orbital scan acquires CBCT volume data for 3D reconstruction.
  • 30 cm × 30 cm flat-panel detector — large field for body / spine 3D coverage.
  • 3D acquisition: 196°+ rotation capturing cone-beam CT data. Reconstruction in ~30 seconds.
  • Metal-artifact reduction in 3D reconstruction — particularly relevant for orthopedic-implant imaging.
  • Touch-screen UI with integrated 3D review tools.
  • DICOM connectivity for surgical-navigation system integration.

Variants in family

  • Cios Alpha — premium 2D.
  • Cios Fusion — mid-tier 2D.
  • Cios Spin (this card) — 2D + 3D.
  • Cios Select — entry 2D (separate card not yet created).

Clinical use

  • Spine surgery — pedicle-screw confirmation, deformity correction, vertebroplasty.
  • Trauma orthopedics — fracture-reduction verification, pelvic / acetabular work.
  • Foot / ankle / wrist — intraoperative 3D confirmation of fixation alignment.
  • General fluoroscopy for the routine 2D workload — same use cases as a conventional Cios Alpha.

Refurb posture

  • Newer line — refurb supply small; first wave of installs not yet at end-of-warranty.
  • Detector + 3D-software-license tier dictate refurb pricing.
  • Cumulative orbital-scan count matters for the 3D drive mechanism — high-volume sites (busy spine programs) wear the 3D-rotation drive faster than the routine 2D motion.
  • Service-network depth for Siemens C-arms is good in mid-tier markets.
