The OEC 9800 features a rotating anode tube. By rotating the anode, this tube type disperses the heat created by generating X-ray evenly around the circumference of the entire anode, allowing the C-arm to take longer exposures at higher doses. If you intend to work with a high volume of patients or to specialize in applications like vascular or bariatrics where the power demands will be higher, a rotating anode is a must.
The OEC 8800 has a stationary anode. All of the heat coming from the cathode lands on the same portion of the anode surface. If used too hard, this can lead to a decline in tube efficiency and eventual failure much sooner than a user might experience with a rotating anode tube. That siad, this tube style works just fine for shorter, low-dose studies. It is also less expensive and smaller, allowing the 8800 to have a smaller footprint overall. If your specialty is more along the lines of sports medicine or pain management, a stationary anode will be sufficient for your needs.
