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…
Prism-array lenses for energy filtering in medical x-ray imaging
Erik Fredenberg, Bjorn Cederstrom, Carolina Ribbing +1
Conventional energy filters for x-ray imaging are based on absorbing materials which attenuate low energy photons, sometimes combined with an absorption edge, thus also discriminat…
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…
Energy filtering with X-ray lenses: optimization for photon-counting mammography
Erik Fredenberg, Bjorn Cederstrom, Mats Danielsson
Chromatic properties of the multi-prism and prism-array X-ray lenses (MPL and PAL) can potentially be utilized for efficient energy filtering and dose reduction in mammography. The…
