Leeds Test Objects′ FLUORO-4 phantom is designed to be used to check the image quality performance of digital and conventional fluoroscopy x-ray systems. These tests should be carried out at acceptance to establish a baseline, and on a routine basis, keeping an on-going record of the test results, which will indicate any deterioration in performance.

FLUORO-4 features the following test details:

  • Tube axis direction markings
  • Limiting spatial resolution (0.6 − 5.0 LP/mm)
  • Low contrast resolution details (8 x 10mm diameter details, depths 0.4 − 4.0 mm)
  • Dynamic range (17 different thickness Cu steps each with a central 4.0mm diameter detail, depth 2.5 mm)
  • kV test-area (Yb 0.78mm)
  • Unstructured inner area (centre-marked)
  • Radiopaque numbers indicating dynamic range steps

FLUORO-4 should be used with either PMMA/Cu or Al attenuator plates (available separately).

The phantom is supplied in a soft protective carry bag.
