Comparison of Image Quality Among Variations in Specimen Tissue Compression and Fluid Immersion for Diffraction Enhanced Imaging
Abstract
The current standard for breast cancer screening and diagnosis is screen-film mammography, which utilizes the principle of x-ray absorption to derive image contrast. A new imaging modality called Diffraction Enhanced Imaging (DEI) builds upon conventional x-ray imaging by adding two additional contrast mechanisms of refraction and scatter. Applications of this technique to breast imaging are promising, demonstrating significant improvements in visualization when compared digital mammography. One of the primary reasons for compressing the breast is to reduce the deleterious effects of x-ray scatter, reducing the total path through which the photon travels. This study seeks to investigate the effects of compression on breast tissue visualization using DEI. Results from this study will be applied to the development of a clinically based DEI system. Four tissues were imaged at different levels of compression using conventional mammography and DEI. A reader study will be used to determine the effect of compression on visualization.
