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…
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…
