Contrast details mammography phantom according to European Protocol for quality assurance in Digital Mammography. It can 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 varying the PMMA thickness.
Product highlights:
- unmatched accuracy – up to 30 times better than other products on the market
- gold disc objects positioned as per EUREF specs
- objects’ diameter, thickness and layout can be modified according to individual specifications
- 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
- Diagnomatic software provides automatic and semi-automatic analysis of phantom’s images, providing all the necessary information like Contrast-Details curve, making quality assurance simple and quick
