Summary

This article, "Development of a Portable Digital Radiographic System Based on FOP-Coupled CMOS Image Sensor and Its Performance Evaluation", describes the development of a portable digital radiographic system. The system was created by a team of researchers: H. S. Cho, M. H. Jeong, B. S. Han, S. Kim, B. S. Lee, H. K. Kim, and S. C. Lee. The researchers published their findings in the IEEE Transactions on Nuclear Science.

The system utilizes a CMOS image sensor paired with a fiber optic plate (FOP) and conventional scintillators. The FOP plays a crucial role by mitigating performance degradation of the CMOS sensor due to irradiation, while simultaneously enhancing the overall image quality. The article provides a detailed overview of each component within the imaging system.

Furthermore, the authors present a performance analysis derived from experimental measurements and X-ray images. The analysis encompasses crucial aspects such as:

  • System response with exposure
  • Contrast-to-noise ratio (CNR)
  • Modulation transfer function (MTF)
  • Noise power spectrum (NPS)
  • Detective quantum efficiency (DQE)

The study highlights the promising image performance achieved by the portable digital radiographic system, particularly in areas like emergency medical vehicles and remote sites.
