This medical equipment item is a subcomponent or part that has been extracted from a larger system or unit. It is intended for use as a replacement part or for integration into another system. Its condition may vary, but it has been removed with care to preserve its functionality.

The GE Proteus 46‑155400G46 / 46‑155318G33 imaging tube—also known as the MX100 09PS with insert part number 2336058—is a replacement X‑ray tube assembly commonly used in GE’s Proteus imaging systems (e.g. Proteus XR/a). It delivers a focal spot of 0.6 mm / 1.25 mm, operates at 40–100 kW, and features the MX‑100 insert design within a compatible housing format.

Professionals describe it as a used, tested part, with listings citing manufacture dates (DOM) including 2011 and October 2018 depending on the vendor. Pricing typically ranges from ~USD 450 for older tubes to several thousand for newer, verified units. The assembly supports systems beyond Proteus, including GE models like the Definium 8000, Discovery, Revolution XRD, and others that share compatible tube interfaces.

This imaging tube is designed to integrate seamlessly with GE’s radiography equipment, offering dose-efficient exposure, auto‑collimation, phototiming, and support for programmable Anatomic Programmed Radiography (APR). While technical design details (e.g. cooling requirements, exact electron path geometry) are proprietary to GE and restricted to internal service documentation, these tubes are typically sourced through authorized vendors or certified refurbishers and require validation for compatibility by system serial number and release version.
