Upgraded contrast details mammography phantom according to European Protocol for quality assurance in Digital Mammography. It may be used to determine if mammographic images indicate objects with very low contrast and very small diameter, to find out the optimum exposure technique, or to compare image quality at various object thicknesses by variation of the amount of PMMA thickness.
Features and Benefits
- Unmatched accuracy – up to 30 times better than other products on the market
- Gold disc objects positioned at depth suggested by EUREF
- Smallest objects are positioned in the middle of the phantom where sensitivity of the x-ray device is the best
- Discs are grouped into five sections relative to the EUREF limiting diameters values (2.0, 1.0, 0.5, 0.25 and 1.0mm)
- Disc thickness are optimized to result in contrast details curves for each diameter to correspond perfectly with EUREF limiting values
- No materials other than PMMA are used, so there is no need to calculate PMMA-equivalent attenuation for other materials such as aluminium
- For full-field analog and digital units
- Pro-Control software provides automatic and semi-automatic analysis of the phantom’s images, providing all the necessary information like Contrast-Details curve, making quality assurance simple and quick
- Each diameter has its own optimized thickness range of 5 mm – 110 mm for the 2.00 mm diameter gold discs to 600 mm – 2800 mm for the 0.08 mm diameter, all in 16 steps
- 2 discs per cell, one disc is placed in the middle and one near the random corner of the cell
- 2 additional 10 mm PMMA plates (thickness accuracy about 0.05mm)
- 2 additional 5 mm PMMA plates (thickness accuracy about 0.05mm)
- Carrying Case is included
