Paper Abstract

Knowledge of x-ray attenuation is essential for developing and evaluating x-ray imaging technologies. For instance, techniques to better characterize cysts at mammography screening would be highly desirable to reduce recalls, but the development is hampered by the lack of attenuation data for cysts. We have developed a method to measure xray attenuation of tissue samples using a prototype photon-counting spectral mammography unit. Spectral (energyresolved) images were acquired and the image signal was mapped to two known reference materials, which were used to derive the x-ray attenuation as a function of energy. We have measured the attenuation of 25 samples of breast cyst fluid. Spectral measurements of water samples showed consistent results compared to published attenuation values.
