The GE OEC 9800 first launched in 1999, and the upgraded version, the GE OEC 9800 plus, introduced in 2002. It was finally discontinued in 2006 just before the GE C ARM manufacturing facility in Utah claimed the recall by FDA in 2006. There has been no successor of the GE OEC 9800 since 2006. The GE OEC 9900 and the GE OEC 9800 are quite similar in terms of specification and clinical utilities, so GE simplified its product line-up and decided to have the OEC 9900 series with an II (Image Intensifier) type C ARM and a CMOS flat panel detector type CARM. From this perspective, in 2017, GE cleared the 510(k) for their CMOS Flat Detector, now incorporated into the GE OEC Elite CFD as a premium grade C-ARM system. The GE OEC 9900 was upgraded with a 1k x 1k CCD camera and the traditional II type is still importantly positioned as a key C-ARM product in the GE C-ARM line-up.

FAQ

AutoTrak is the function that automatically seeks the subject anatomy anywhere within the imaging field and selects optimal imaging. It automatically adjusts to anatomical size and location.

Automatic Brightness Stabilization (ABS) is the function that provides uniform image quality throughout the entire image. Unlike a CFD C-ARM, an II type C-ARM by nature has imaging distortion and brightness uniformity issues. These problems worsen it gets closer to the edge.
Smart Window is the function that dynamically senses the collimator position and automatically adjusts brightness and contrast to produce high image quality.

Smart Metal is the function that allow users to adjust automatic brightness and contrast sensitivity levels when metal is introduced to the field.

Tungsten Collimator is the function that denser collimator limits X-ray exposure area to reduce scatter radiation, which improves image detail.

The GE OEC 9800 first launched in 1999, and the upgraded version, the GE OEC 9800 plus, introduced in 2002. It was finally discontinued in 2006 just before the GE C ARM manufacturing facility in Utah claimed the recall by FDA in 2006. There has been no successor of the GE OEC 9800 since 2006. The GE OEC 9900 and the GE OEC 9800 are quite similar in terms of specification and clinical utilities, so GE simplified its product line-up and decided to have the OEC 9900 series with an II (Image Intensifier) type C ARM and a CMOS flat panel detector type CARM. From this perspective, in 2017, GE cleared the 510(k) for their CMOS Flat Detector, now incorporated into the GE OEC Elite CFD as a premium grade C-ARM system. The GE OEC 9900 was upgraded with a 1k x 1k CCD camera and the traditional II type is still importantly positioned as a key C-ARM product in the GE C-ARM line-up.

The GE OEC 9800 has the same clinical packages of those of the GE OEC 9900 – GSP (General Surgical Package), ESP (Extended Surgical Package, Vascular Package with 4/8/15/30 Frames per Second (FPS), Neurovascular Package, and Cardiac Package. Most packages are not standard, but optional. Cost of package varies. Due to the similarity of packages in the two systems, the learning curve is shorter if a user gets used to one of the GE OEC C-ARM series.

The GE OEC 9800 offers 9″ or 12″ image intensifiers, a 15kW rotating anode X-ray tube, a passive tube cooling system (Outdated cooling concept, an active cooling system is much more efficient), a smaller focal spot, large tube capacity up to 300,000HU, a faster cooling rate 70,000HU/min, and 8 pulses per second available on pulsed fluoroscopic mode. In terms of features and system capacity, the OEC 9900 and OEC9800 (Plus) are very close except for some minor features. Also, the GE OEC 9800 has dual 16″ CRT monitors, and the CRT monitors fixed on the workstation. The GE OEC 9800 unfortunately does not support USB/DVD storage.

Both the GE OEC 9800 and OEC 9900 come with DICOM, which can be connected to a PACS system. The image storage capacity on the GE OEC 9800 GSP package and the GE OEC 9800 ESP package is 63 and 1,000 respectively.

The GE OEC 9800 owns a very old platform, but its user interface and imaging options are still accepted due to its cost-efficiency compared to new C ARM systems in the market. The GE OEC 9800 provides similar features to other GE OEC series such as Auto Track, Automatic Brightness Stabilization (ABS), Smart Window, Smart Metal, Tungsten Collimator, battery buffered technology working like an UPS (Universal Power Supply), and optional Digital Subtraction Angiography (DSA) upon applicable clinical package selection. The GE OEC 9800 collimator enables adjustments of collimators without X-ray exposure, while also reviewing target images on Preview mode with features of Preview iris collimator and PreView Tungsten rotatable double leaf collimator.

The GE OEC 9800 systems currently in the refurbished market are 10 to 20 years-old. Due to the high price position of the new OEC Elite and OEC Elite CFD series, which are around 200,000 US dollars, refurbished (about 10 to 20 years old) GE OEC 9800 systems are still very popular. 10 out 6 or 7 mobile C ARMs sold in the current US market are a refurbished GE OEC 9800, and are being sold between 70,000 and 90,000 US dollars depending on options and parties; whether refurbished by GE itself or a third party ISO(Independent Service Organizations). However, the price of parts and repairs are still very expensive and it is difficult to get those parts to reduce the system down time.

The GE OEC 9900 and OEC 9800 are very similar in features and performance. A few added features and an articulating flat panel monitor of the GE OEC 9900 are difficult to justify such a high additional cost compared to the OEC 9800. Hundreds of units of the refurbished OEC 9800 are sold in USA every year, so customers have more alternatives to find a place for repairs and parts for the GE OEC 9800, rather than the GE OEC 9900. However, almost 15 to 20 years of pre-owned medical equipment in tough clinical environments may have higher risks of problems on mechanical parts and lowered functionality on X-ray tubes, as well as other generator and power supplies. Unless covered by expensive warranty by GE or ISO (Independent Service Organizations), the cost of repair will be extremely high.

One of the major strengths of having the GE OEC 9800 is that this system is clinically proven to provide extended imaging modes (Fluoro Mode, Pulsed Fluoro Mode, High Level Pulsed Fluoro, Digital Cine Pulse Mode, Digital Spot Mode, and Radiographic Mode) and clinical packages like current, top-selling C-ARM system competitors. The 15kW generator power is well accepted and not limited most examinations. Its rotating X-ray tube makes the system last long enough to perform complicated neurovascular and cardiac procedures as well. In addition, the mechanical apparatus of the GE OEC 9800 is known to be very durable, so unless there is a power supplier, monitor, or other electrical issue, this 15 year-old and more refurbished system is still usable. Positioning of the system is relatively easy with smooth maneuverability and wheeling, but its 115° limited orbital rotation often gives operational inconvenience, which can significantly disturb a smooth operation procedure.

In conclusion, the refurbished GE OEC 9800 is a cost efficient and popular system because there has not been a replaceable system with reasonable price and quality. The GE OEC 9800 is known as durable, however, most pre-owned GE OEC 9800 systems in the market are more than 15 years old. Generally, refurbished OEC series are offered with limited warranty; either one year or no warranty at all. If a customer wants to purchase a C-ARM for next 5 to 10 years, the customer must consider maintenance costs and parts scarcity within 1 to 2 years. A very limited number of people still have a CRT monitor TV or a 2G flip phone; however, a large portion of physicians still purchase a pre-owned C-ARM, since an up-to-date and fully digital interfaced C-ARM is still too expensive. Considering all this background, what if there is a brand-new CFD C-ARM with 2 to 5 years warranty, proven durability and quality in more than 300 clinical sites in USA, and is inexpensive compared to the refurbished GE OEC 9800 – don’t we need to consider the brand-new, affordable CFD C-ARM as your system for next 10 years?
