What Is a C-Arm Machine?

According to the Centeno-Schulz Clinic, a C-arm machine is a device used by a physician to guide surgical instruments while watching the instrument being driven on a live x-ray machine. The C-arm is also referred to as an X-ray image intensifer, or XRII.

According to Amber Diagnostics, the C-arm machine can be used in various surgical and non-surgical procedures. Originally used in the orthopedic surgery discipline, its use has expanded to include the areas of pain management, cardiology, minimally invasive surgeries, urology, spinal and neurovascular applications. The C-arm consists of an input window, input and output phosphor, output window, electron optics, photocathode and vacuum.
