Device Story
PHOT-X II Model 303 is an extraoral dental X-ray system consisting of a control box, wall mount, adjustable support arm, and X-ray tubehead. It generates X-rays for diagnostic imaging of human teeth, with output captured on intraoral film or digital receptors. Operated by dental professionals in clinical settings, the device uses an 80 kHz high-frequency inverter circuit to produce X-rays. A microprocessor monitors tube current (mA) to automatically adjust pre-heating time, ensuring consistent radiation output. The control panel and power circuit board are separable via serial communication circuits. By providing controlled X-ray exposure, the device enables clinicians to visualize dental structures, facilitating diagnosis of oral diseases. Benefits include improved diagnostic accuracy through stable X-ray generation and flexible positioning for patient imaging.
Clinical Evidence
Bench testing only. No clinical data provided. Substantial equivalence is supported by comparative electrical and radiation performance data, including focal point measurement, tube potential, tube current, timer accuracy, and filtration characteristics, demonstrating performance consistent with predicate devices.
Technological Characteristics
Extraoral dental X-ray system. 80 kHz high-frequency inverter circuit with Cockcroft circuit. Features microprocessor-controlled pre-heating system. Focal point 0.7mm x 0.7mm. Rated tube potential 60kV/70kV; tube current 4mA/7mA. Inherent filtration 1.7mm Al equivalent. Connectivity via serial communication between control panel and power circuit board. Wall-mounted form factor.
Indications for Use
Indicated for use as an extraoral source dental radiographic x-ray unit for diagnostic imaging of human teeth, with images recorded on intraoral dental x-ray film or image receptor. For prescription use.
Regulatory Classification
Identification
An extraoral source x-ray system is an AC-powered device that produces x-rays and is intended for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structures. The x-ray source (a tube) is located outside the mouth. This generic type of device may include patient and equipment supports and component parts.
