October 17, 2014 — Spellman High Voltage Electronics Corp. announces the introduction of its new PDM Dental Monoblock X-Ray Source. This compact and lightweight, integrated high-voltage power supply, filament power supply and X-ray tube assembly is ideal for panoramic/cephalometric/computed tomography (CT) dental imaging.
For 2-D panoramic imaging applications, Spellman’s new PDM can operate for a maximum of 30 seconds continuously at 900 watts. A maximum of five consecutive scans are possible with 60 seconds between scans. The PDM also supports 3-D CT imaging applications. The maximum CT scan time is 45 seconds at 40 pulses per second.
The PDM’s X-ray tube voltages are adjustable from 50 kV to 90 kV with tube current capability from 1 mA to 10 mA, delivering a peak power output of 900 watts with a focal spot size of 0.5 mm. A power factor corrected universal input front end minimizes input currents while complying with worldwide input voltage requirements. The PDM can be controlled from either an analog or RS-232 digital interface, providing flexibility in system integration.
This compact unit’s X-ray tank size is only 247x119x195 mm, with a separate control assembly at 180x92x250 mm, which allows for ease of OEM integration. As with all Spellman products, customization is available based on unique application requirements.
