PDM Series Monoblock® X-Ray Generators

  • X-Ray Source with Integrated Filament, Tube and Beam Port
  • Separate Control Electronics Box
  • Compact & Lightweight
  • Analog or Digital Control Interface

Panoramic Dental X-Ray Source

Spellman’s new Panoramic Dental Monoblock consists of an integrated X-Ray tube, dual-output high voltage power supply, and filament supply with control circuitry. The PDM is designed for extra oral dental X-Ray applications includ­ing CT and Panoramic X-Ray. Features like small package size, standard analog and RS-232 digital interface simplify integrating the PDM into your X-Ray system. Proprietary emission control circuitry provides excellent regulation of X-Ray tube current, along with outstanding stability and performance. 

Typical applications:

  • Dental X-Ray: Panoramic and CT Imaging
