This is a simple and efficient-to-use routine medical imaging test phantom which is used daily to evaluate the imaging performance of mammography 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
Imaging contrast: low-contrast resolution (1.8 to 5 line pairs/mm) and high-contrast resolution (1.0 to 20.0 line pairs)
Greyscale and Sensitometric measurements
Resolution limits (1.0 to 20.0 Line pairs/mm)
Low-contrast large-detail detectability (12 details of 5.6mm diameter) and High-contrast small-detail detectability (11 details of 0.5 and 0.25mm diameter)
Micro-calcifications replication of average sizes 125, 225 and 325 microns
omogeneity
Free area for signal calibration
