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…
Performance of three-photon PET imaging: Monte Carlo simulations
Krzysztof Kacperski, Nicholas M. Spyrou
We have recently introduced the idea of making use of three-photon positron annihilations in positron emission tomography. In this paper the basic characteristics of the three-gamm…
