GE AMX 4
The GE AMX 4 is a classic, battery-powered portable X-ray system designed for dependable radiographic imaging wherever patients need care.
The GE AMX 4 is a classic, battery-powered portable X-ray system designed for dependable radiographic imaging wherever patients need care. Operating entirely from an onboard rechargeable battery pack, the AMX 4 delivers full-power exposures without requiring a wall outlet, making it ideal for ICUs, CCUs, emergency rooms, ORs, orthopedic suites, clinics, pediatric and neonatal units. This system features the MX-75, 275 kHU X-ray tube with a 0.75 mm focal spot, combined with a GE AMX-IV collimator for reliable, high-quality imaging across a wide range of procedures. Variable forward and reverse drive speeds and its fully mobile design allow technologists to position the unit quickly and safely at the bedside. With 24 kVp stations, 30 mAs stations, and consistent 100 mA output, the AMX 4 provides flexible technique selection to meet diverse clinical demands. An LED display and intuitive controls further enhance usability in busy hospital environments.
