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…
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…
An efficient pre-object collimator based on an x-ray lens
Erik Fredenberg, Bjorn Cederstrom, Magnus Aslund +2
A multi-prism lens (MPL) is a refractive x-ray lens with one-dimensional focusing properties. If used as a pre-object collimator in a scanning system for medical x-ray imaging, it…
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.…
