Compact Space Saving Modular Format
Fast Rise and Fall Times Help Minimize Unnecessary Patient Radiation Exposure
Dual Speed Starter, Boost/Brake Capability
RS-232 and Optional Ethernet Interfaces

Certifications & Compliance

Spellman’s PMX is a high performance X-Ray generator designed specifically for mammography applications including FFDM and DBT. It features 2 and 3 point exposure modes as well as smart AEC with a pre-exposure.

The PMX is a 5kW high frequency X-Ray generator integrated with a dual filament power supply, and a dual-speed X-Ray tube starter. Due to the PMX's superior power conversion technology and inverter design it can provide stable and accurate X-Ray tube high voltage with fast rise and fall times.

Smooth system integration of the PMX is accomplished through the use of RS-232 and optional Ethernet digital interface, pre-loaded X-Ray tube parameters, easy access interlocks and I/O connections, and internal generator diagnostics. Optional GUI utility software is also offered to help with initial system integration.
