Three-Photon Bayesian Imaging of Ortho-Positronium
L. Raczynski, W. Krzemien, A. Coussat +5
PET provides functional images relying on two-photon coincidences from positron-electron annihilation. In human tissue, about 40\% of annihilations are preceded by Ps formation, of…
A systematic evaluation of machine learning classifiers for event-by-event background rejection in LAFOV PET scanners
Konrad Klimaszewski, MichaÅ Obara, Mateusz Bala +5
The paper evaluates machine‑learning classifiers (XGBoost, AdaBoost, neural networks) for classifying individual PET coincidence events to reduce background in large‑field‑of‑view…
CAD-to-CT Registration of Cylindrical Objects via Ellipse-Based Axis Estimation
Aleksander Ogonowski, MikoÅaj Mrozowski, Daniel WiÄcek +9
Accurate registration of CAD models to CT scans is essential for establishing ground truth geometry in volumetric imaging. Obtaining reliable object masks is of growing importance…
DSS-GAN: Directional State Space GAN with Mamba backbone for Class-Conditional Image Synthesis
Aleksander Ogonowski, Konrad Klimaszewski, PrzemysÅaw Rokita
We present DSS-GAN, the first generative adversarial network to employ Mamba as a hierarchical generator backbone for noise-to-image synthesis. The central contribution is Directio…
Preliminary study on artificial intelligence methods for cybersecurity threat detection in computer networks based on raw data packets
Aleksander Ogonowski, MichaÅ Å»ebrowski, Arkadiusz Äwiek +5
Most of the intrusion detection methods in computer networks are based on traffic flow characteristics. However, this approach may not fully exploit the potential of deep learning…
