Flat-panel detectors are transforming medical imaging, offering improved workflow, image quality, and dose reduction in radiography and mammography. These advanced X-ray detectors are also emerging in angiography and fluoroscopy, enabling new diagnostic possibilities.

Area of Science:

  • Medical physics and imaging technology.
  • Radiological sciences.
  • Biomedical engineering.

Context:

  • Flat-panel detectors (FPDs) are increasingly adopted across various X-ray imaging applications.
  • While established in digital radiography, mammography, and cardiologic angiography, FPDs are entering general angiography and fluoroscopy.
  • Two primary FPD technologies exist: indirect and direct X-ray conversion.

Purpose:

  • To review the market penetration and technological aspects of flat-panel detectors in medical X-ray systems.
  • To compare the advantages of indirect and direct conversion FPDs for different applications.
  • To highlight the benefits and potential of FPDs in radiography, mammography, angiography, and fluoroscopy.

Summary:

  • FPDs offer significant improvements in workflow, image quality, and dose reduction in radiography and mammography due to immediate image availability, large dynamic range, and high X-ray sensitivity.
