Lesion characterization in spectral photon-counting tomosynthesis
Bjorn Cederstrom, Erik Fredenberg, Karl Berggren +3
It has previously been shown that 2D spectral mammography can be used to discriminate between (likely benign) cystic and (potentially malignant) solid lesions in order to reduce un…
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…
Optimization of mammography with respect to anatomical noise
Erik Fredenberg, Bjorn Svensson, Mats Danielsson +2
Beam quality optimization in mammography traditionally considers detection of a target obscured by quantum noise on a homogenous background. It can be argued that this scheme does…
