The DenOptix storage phosphor system showed better performance than the Digora system. However, Digora achieved similar results with image enhancement, offering comparable diagnostic imaging quality.

Area of Science:

  • Radiology
  • Medical Imaging Technology

Background:

  • Storage phosphor imaging plates are widely used in digital radiography.
  • Comparing the performance of different imaging systems is crucial for optimizing diagnostic accuracy.

Purpose of the Study:

  • To compare the physical performance of two storage phosphor imaging plate systems: Digora and DenOptix.
  • Evaluate their effectiveness with and without default settings.

Main Methods:

  • Physical and psychophysical measurements were conducted on both systems.
  • Test phantoms included aluminum blocks and a resolving power target.
  • Key performance metrics assessed were dose response, contrast index, modulation transfer function (MTF), and noise levels.

Main Results:

  • DenOptix demonstrated superior dose response, contrast index, and MTF compared to Digora at default settings.
  • DenOptix exhibited higher noise levels than Digora at lower exposure doses.

Conclusions:

  • DenOptix offers higher performance out-of-the-box.
  • Digora can achieve comparable performance to DenOptix when image enhancement algorithms are applied, suggesting flexibility in image optimization.
