SFS Set

Prüfset für Standard-Fluoroscopie und Fluorographie-Systeme nach IPEM 91

Sechs Prüfobjekte in einem Koffer zur Qualitätskontrolle in Fluoroskopie und Fluorographie gemäß IPEM 91 (UK) Richtlinie.

Technische Spezifikationen

  • VS4 object to check peak white and black level in conjunction with an oscilloscope
  • SW4 object for checking greyscale linearity (nominal 10% contrast steps), peak white and black level (2 detail objects) for adjustment of monitor brightness/contrast. Plus circular geometry test (for television scan linearity)
  • FSG4 object for checking field size and geometry (10mm field size spacings, 20mm geometry spacings)
  • Type 18 Line Pair Pattern (Resolution limit 0.5 to 5.0 lp/mm) to adjust electronic/optical focusing
  • SSM4 object for checking focal homogeneity over the image field (Spatial frequency 0.86 cycles mm-1)
  • LCD4 object for checking low-contrast sensitivity (19 details, 11 mm in diameter, with a contrast range 14.8% to 0.42%) to quantify noise plus contrast loss
  • TCD4 for threshold-contrast detail-detectability (108 details in 12 sizes, 9 contrasts) to plot the Contrast Detail Index for overall image quality
  • Video cable with three connectors
  • Additional Copper Filters (2x 0.5 mm, 1x 1.0 mm Cu) for beam calibration
