Rayleigh imaging in spectral mammography

Karl Berggren, Mats Danielsson, Erik Fredenberg

Spectral imaging is the acquisition of multiple images of an object at different energy spectra. In mammography, dual-energy imaging (spectral imaging with two energy levels) has b…

X-ray attenuation of adipose breast tissue: in-vitro and in-vivo measurements using spectral imaging

Erik Fredenberg, Klaus Erhard, Karl Berggren +10

The development of new x-ray imaging techniques often requires prior knowledge of tissue attenuation, but the sources of such information are sparse. We have measured the attenuati…

Photon-counting spectral phase-contrast mammography

E. Fredenberg, E. Roessl, T. Koehler +10

Phase-contrast imaging is an emerging technology that may increase the signal-difference-to-noise ratio in medical imaging. One of the most promising phase-contrast techniques is T…

Lesion characterization using spectral mammography

Bjorn Norell, Erik Fredenberg, Karin Leifland +2

We present a novel method for characterizing mammographic findings using spectral imaging without the use of contrast agent. Within a statistical framework, suspicious findings are…

Measurement of breast-tissue x-ray attenuation by spectral mammography: first results on cyst fluid

Erik Fredenberg, David R. Dance, Paula Willsher +4

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…

Volumetric breast-density measurement using spectral photon-counting tomosynthesis: First clinical results

Erik Fredenberg, Karl Berggren, Matthias Bartels +1

Measurements of breast density have the potential to improve the efficiency and reduce the cost of screening mammography through personalized screening. Breast density has traditio…
