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…

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…

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…
