This is a simple and efficient-to-use routine medical imaging test phantom which is used daily to evaluate the imaging performance of digital fluoroscopic systems. You can simply check the grey-scale, count the number of contrast details and resolve the line patterns. If these numbers ever avert from the norm then this may indicate deterioration of image quality in your fluoroscopic imaging system.
It allows for evaluation of:
Brightness and contrast adjustment: Cu for High light & Pb for low light details
Geometry check: scanning linearity
Imaging contrast: 18 low-contrast and high-contrast details with contrast values from 0.9 to 16.7% @70kVp 1mm Cu, 8mm diameter.
Resolution: 0.5 to 5.0 Line pairs/mm
Geometry and collimation check markings
