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…
Observer model optimization of a spectral mammography system
Erik Fredenberg, Magnus Aslund, Bjorn Cederstrom +2
Spectral imaging is a method in medical x-ray imaging to extract information about the object constituents by the material-specific energy dependence of x-ray attenuation. Contrast…
A photon-counting detector for dual-energy breast tomosynthesis
Erik Fredenberg, Mats Lundqvist, Magnus Aslund +3
We present the first evaluation of a recently developed silicon-strip detector for photon-counting dual-energy breast tomosynthesis. The detector is well suited for tomosynthesis w…
Contrast-enhanced dual-energy subtraction imaging using electronic spectrum-splitting and multi-prism x-ray lenses
Erik Fredenberg, Bjorn Cederstrom, Mats Lundqvist +5
Dual-energy subtraction imaging (DES) is a method to improve the detectability of contrast agents over a lumpy background. Two images, acquired at x-ray energies above and below an…
