VMX
- Custom Designed Specifically for Mammography Applications
- Fast Settling Helps Minimize Patient Radiation Exposure
- Dual Speed Starter, Boost/Brake Capability
- RS-232 and Optional Ethernet Interfaces
- Low Cost, Value Added, Modular Design
Certifications & Compliance
Spellman’s VMX redefines the standard for high performance, low cost Mammography X-Ray generators. The VMX was born from an integrated, high performance, value added design perspective so there’s no need to compromise critical specifications to meet ever demanding system price targets.
The 40kV/5kW X-Ray generator integrates a dual filament power supply and a dual speed starter. A DC current source filament power supply provides fast rise times with stable and accurate X-Ray tube emission currents. The solid encapsulated high voltage output section eliminates oil concerns while reducing the effects of environmental humidity and contamination.
Flexibility in interfacing is provided via RS-232 and optional Ethernet connectivity. The VMX supports advanced mammography application features including Smart AEC Exposure, Automatic Filament Calibration, Tube Anode Heat Calculator and user configurable tube library. Compact, full featured,high performance, low cost. Spellman’s VMX, the next generation Mammography X-Ray generator.
