GE OEC 9800 Plus
Family: OEC 9800 · Modality: C-Arm / Mobile Fluoroscopy
High-resolution imaging-chain configuration of the 9800. The defining difference from the rest of the family is the 1024 × 1024 image matrix — four times the pixel count of the 512 × 512 matrix used on Standard 9″, Standard 12″, Super-C, and MD. The Plus designation describes the imaging chain and workstation monitors, not a separate chassis: Plus systems share the 9800 mainframe, generator, tube, and mechanics with other variants. The Plus imaging chain is typically paired with Standard 9″ geometry but does appear on other geometries.
What Plus changes
- 1024 × 1024 acquisition and display matrix — the full imaging-chain step up is acquisition, frame processing, and monitor display. Clinically meaningful for fine bone work, small-implant placement (spine hardware, dental, ortho small-fragment), and cardiac / peripheral where pixel count matters at the limits of the image intensifier's resolution.
- High-resolution monitors on the cart — the station monitors pair with the imaging chain; mismatched calibration between station and the workstation (when one has been swapped without the other) is a common field finding.
- Imaging-chain-only upgrade path — a Standard can be re-imaging-chained to Plus, but economics are rarely favorable versus sourcing a Plus-configured unit at the outset.
Specs
- 9″ tri-mode image intensifier (9 / 6 / 4.5 configurations, typical)
- 1024 × 1024 image matrix (this variant's distinguishing feature)
- 15 kW high-frequency generator · 120 kVp · 75 mA radiographic · 40 mA pulsed fluoro
- Rotating-anode tube · 0.3 / 0.6 mm dual focal spot
- 300,000 HU anode heat capacity
- Dual high-resolution monitors on the cart
- Software licensing tiers same as rest of 9800 family (GSP / ESP / ESP8 / Vascular / NeuroVascular / Cardiac)
Clinical positioning
- Fine-detail orthopedic — spine hardware placement, small-fragment fixation, foot/ankle, hand.
- Pain management — high-detail needle-tip and catheter placement.
- Interventional cardiology in OR settings — when a dedicated cath lab is not in scope but pixel count matters.
- Small-anatomy pediatric and extremity work.
Parts
Variant-specific: HD imaging chain + cart monitors. Everything else (filament driver, SBC, tube, generator, gantry) is cross-compatible across the 9800 family — see family page for shared part list.
Acceptance-test note
A resolution phantom side-by-side comparison between a Plus and a Standard is the single cleanest way to confirm Plus imaging-chain integrity: if the resolution improvement is not visible, the imaging chain has been swapped back or is degraded. Station-monitor and workstation-monitor calibration must match; physicians pick up mismatch quickly.
Relationship to siblings
- 9800 Standard 9″ — 512 × 512 matrix sibling; most common 9800 configuration.
- 9800 Standard 12″ — larger II for broader anatomy.
- 9800 Super-C — deeper arc geometry.
- 9800 MD — motor-driven positioning.
