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…
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…
Contrast-enhanced spectral mammography with a photon-counting detector
Erik Fredenberg, Magnus Hemmendorff, Bjorn Cederstrom +2
Purpose: 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.…
