The GE OEC 9900 Elite is a common choice on the refurbished C-arm market, but "OEC 9900" on a listing tells you surprisingly little. The same model name covers different image intensifier sizes, C-arm depths and software packages, and the right combination depends on the cases you run. This page explains each option so you can read a listing and know what you are buying. For the full range of C-arms and service, see our C-arm machine repair, sales and rental in Texas page.
Image intensifier size and C type
| Configuration | Typical use | Notes |
|---|---|---|
| 9-inch, standard C | Orthopedics, pain management, general surgery, pacemakers, sports medicine | The most common and the most affordable |
| 12-inch, standard C | Vascular, neurovascular and orthopedics | A larger field of view in one image |
| 9-inch, Super C | Larger patients and cardiac work | About 7 inches deeper than the standard 9-inch C, with 33° more rotation; only offered with the 9-inch intensifier |
| Motorized 9-inch or 12-inch | Rooms where the C is positioned often during a case | Joystick-controlled movement; the motorized 12-inch uses the Super C size |

Software packages, from basic to vascular
Each package builds on the one before it:
- GSP (general surgery): digital spot, pulsed fluoroscopy, averaging and edge enhancement.
- ESP: more image storage, digital zoom and roam.
- ESP with 15 fps digital disk: up to 10 minutes of recording with playback and frame-by-frame review.
- PMCare: real-time subtraction and DSA with an 8 fps digital disk.
- Basic Vascular: DSA, roadmapping and 8 fps cine.
- Vascular MTS: motion-tolerant subtraction, 30 fps recording and digital cine pulse mode.
- Cardiac with interventional vascular: 30 fps cine, a three-pedal footswitch and a curved collimator leaf, always on the Super C.
Match the configuration to your cases
- Orthopedic and pain practices: a 9-inch standard C with GSP or ESP covers almost everything.
- General surgery and pacemaker work: 9-inch standard C; add storage if you document many images.
- Vascular programs: a 12-inch C with Basic Vascular or Vascular MTS.
- Cardiac and larger patients: the 9-inch Super C with the cardiac package.
Checking a used OEC 9900
Confirm the installed software package on the system itself, not just in the listing; ask for the tube's history and phantom images; and check that the monitor cart belongs to the same system. Comparing it with the older model? Our OEC 9600 versus 9900 guide covers the differences. In Texas, the facility needs a current DSHS registration and the C-arm an equipment performance evaluation within 30 days of installation.
The workstation and monitors
An OEC 9900 is two pieces: the C-arm itself and the workstation cart with its monitors, image processing and storage. When comparing listings, look at the workstation as carefully as the C-arm:
- Monitors: check brightness, dead pixels and burn-in. Original monitors on older carts may no longer be available, so ask whether replacements have been fitted and what they are.
- Storage: how many images and runs the workstation holds, and whether old patient data has been cleared.
- Connectivity: whether DICOM output is installed and licensed, and what export options exist, such as USB or disc.
- Printer: if your practice still prints images, confirm the printer works and supplies are available.
Accessories that often go missing
Used OEC 9900 systems are sometimes sold without the small items that make daily use easier. Confirm these are included and working before you agree a price:
- Footswitch and hand switch
- Interconnect cable between the C-arm and the workstation, at a length that suits your room
- Laser aimer, if the configuration includes one
- Sterile drape supply or a source for drapes that fit the model
- Operator manual for the software version installed
Questions to ask the seller about a specific 9900
- What is the image intensifier size, and is it a standard or Super C?
- Which software packages are licensed on this serial number?
- Is the tube original, and is there any usage history?
- Which parts were replaced during refurbishment?
- Can you send images taken on this unit in the last week?
- What warranty applies? Ours is 90 days on reconditioned systems.
A seller who can answer these in writing, with the serial number, is giving you what you need to compare one 9900 with another. If you are deciding between the 9900 and a newer generation, our guide to image intensifier and flat-panel C-arms explains the trade-offs.
Keeping a 9900 running
The OEC 9900 has a large installed base, which helps keep parts available, but it is an older platform. Book preventive maintenance on the manufacturer's schedule, keep the cables and footswitch in good condition, and log error codes when they appear. Ask how long parts such as monitors, tubes and power supplies take to arrive for your configuration, so a failure doesn't leave you without imaging for longer than necessary.
After the purchase, our OEC 9900 repair and preventive maintenance team keeps it running. To ask which OEC 9900 configurations are in stock, call (469) 767-8853 or send us a request.
