dc.description.abstract The mammography is examination of x – ray to early detection of the breast cancer. However the delectability of micro calcifications is required high quality image. Thus evaluation of image quality is important. The main objective of this study was to evaluate image quality for full field digital mammography at omer sawey hospital Khartoum state - Sudan. The tests that were performed in this study include: Contrast to noise ratio and spatial resolution. Contrast to noise ratio was evaluated by acquiring images for different thickness (20, 40, 60, 70 mm) of PMMA phantom and aluminum sheets 0.2mm thickness (as contrast object) and analysis image by image J software. Spatial resolution was evaluated by acquiring image for (3.5mm) of PMMA phantom and bar pattern as lp/mm. Result of this study: the contrast to noise ratio for 9 20, 40, 60, 70 mm) was (213,211,200, 184.8) respectively and spatial resolution for (3.5mm) was (18lp/mm). Conclusion: contrast to noise ration and spatial resolution was found within acceptable value according to European protocol. III en_US
