Summary

This study compared film/screen and charge-coupled device (CCD) receptors in panoramic radiography. While film offered slightly higher spatial resolution, the CCD significantly reduced patient skin exposure by over 70%.

Area of Science:

  • Dental imaging
  • Radiology
  • Medical physics

Background:

  • Panoramic radiography is a standard diagnostic tool for mandibular fractures in emergency settings and dentistry.
  • Traditional imaging utilizes film/screen receptors, prompting investigation into advanced digital alternatives.
  • Assessing image quality and radiation dose is crucial for optimizing patient care.

Purpose of the Study:

  • To compare spatial resolution, distortion, and radiation dose between film/screen and charge-coupled device (CCD) receptors in panoramic radiography.
  • To evaluate the clinical implications of using CCD technology for dental and emergency room imaging.
  • To determine the trade-offs between image quality parameters and radiation safety.

Main Methods:

  • Spatial resolution was assessed using a lead resolution grid at various beam angulations.

  • Image distortion factors were analyzed for both receptor types.
  • Radiation exposure was measured using a RANDO phantom and an ionization chamber.

    • Main Results:

    • Maximum spatial resolution with film/screen was approximately 5 lp mm-1, while the CCD achieved just over 4 lp mm-1.
    • The image layer width was slightly reduced with the CCD receptor.
    • CCD utilization led to a skin exposure reduction exceeding 70% compared to film/screen.

    Conclusions:

    • Charge-coupled device receptors offer substantial radiation dose reduction in panoramic radiography.
    • While spatial resolution is marginally lower with CCDs, the significant dose savings are clinically advantageous.
    • CCD technology presents a viable and safer alternative for routine panoramic imaging.
