Polarization-dependent mode coupling in hyperbolic nanospheres
Krzysztof M. Czajkowski, Maria Bancerek, Alexander Korneluk +2
Hyperbolic materials offer a much wider freedom in designing optical properties of nanostructures than ones with isotropic and elliptical dispersion, both metallic or dielectric. H…
Reduced effective scanning time in SPECT due to OSEM accelerated reconstruction
Krzysztof Kacperski, Dominika Świtlik, Jakub Pietrzak
We study the increase of image noise which can be observed in images reconstructed with the OSEM algorithm. We argue that the excessive noise is equivalent to shortening scanning t…
High Sensitivity Collimators for Optimising Lesion Detection in SPECT Images
Krzysztof Kacperski, Dominika Świtlik, Jakub Pietrzak
Parallel hole collimators which are currently routinely used in SPECT imaging were designed a few decades ago, when filtered backprojection (FBP) was used for tomographic reconstru…
