GE AMX 4 plus mobile X-Ray Machine

When you need to get to a patient fast, you need a durable, mobile X-ray imaging system.GE Healthcare’s AMX-4+ analog X-ray system answers that challenge by providing high-performance in a compact, easy-to-maneuver package. The rotating arm and tube simplify positioning and facilitate bedside studies, while the maintenance-free battery produces up to 50 high-quality exposures with a single charge.

• It has a full counterbalanced collimator/tube assembly, with the center of gravity at points of rotation, so tube stays positioned through light friction locks without the need for adjustable locks. Detents at ± 90° for both axes.
• Ergonomic handswitch controls prep/expose and the collimator light. The handswitch is molded from a lightweight, impact-resistant plastic.
• Compact manual collimator with built-in SID button-on collimator face. Skin spacer is provided to meet BRH requirements of 30 cm focal spot to skin minimum distance. Rotary knobs adjust field size with calibrations at 100 cm and 180 cm (40 in and 72 in).
• Electromechanical friction locks for column rotation, arm elevation and arm extension movements. Locks are released with a single switch on collimator.

More information

GE AMX 4 Plus Portable X-Ray Machine is not only technically refurbished but also cosmetically refurbished to make it work and look like new. When the refurbishing process starts on the X-Ray machine, it is carefully inspected and tested by our own in-house biomedical engineers that are highly skilled and certified to work on X-rays. If necessary, parts are replaced to make sure that all aspects of the GE AMX 4 Plus Portable X-Ray Machine are functioning properly. Once everything is in working order, the unit is calibrated back to the original engineering manufacturer specifications. This ensures that the unit is working the same way that it originally left the manufacturer. After the GE AMX 4 Plus Portable X-Ray Machine is working like new it undergoes a special cosmetic restoration process. The is cleaned, minor scratches and dents are repaired, it’s painted, and new decals GE AMX 4 Plus Portable X-Ray Machine are replaced if necessary. After this strenuous refurbishing process, the Unit functions and looks like new. Before the GE AMX 4 Plus Portable X-Ray Machine is labeled patient-ready and packed up for shipment, it goes through one last quality control test that makes sure all aspects are again working as they should.
