Development and Performance of an Instrumentation Laboratory for Infrared Medical Imaging
Anna Frixou, Efstathios Stiliaris, Costas N. Papanicolas
We present an experimental setup and methodology designed to facilitate high-precision thermal measurements required for infrared medical tomography. The approach which is best sui…
Hamiltonian dynamics for stochastic reconstruction in emission tomography
T. Leontiou, A. Frixou, E. Ttofi +6
Objective: To develop a practical stochastic reconstruction framework for emission tomography that generates ensembles of data-compatible images and enables uncertainty quantificat…
Standardized Images and Evaluation Metrics for Tomography
Anna Frixou, Theodoros Leontiou, Efstathios Stiliaris +1
Advances in instrumentation and computation have enabled increasingly sophisticated tomographic reconstruction methods. However, existing evaluation practices -- often based on sim…
Attributing Uncertainties in the Identification of Hotspots in SPECT Imaging
Costas N. Papanicolas, Loizos Koutsantonis, Efstathios Stiliaris
In SPECT imaging, the identification and detection of a lesion rely either on visual inspection of the reconstructed tomographic images or post-processing image analysis methods. B…
Decoding the QCD critical behaviour in A+A collisions
Nikolaos G. Antoniou, Nikolaos Davis, Fotios K. Diakonos +8
In a systematic search for the QCD critical point in nuclear collisions, at the CERN SPS, it was found that intermittency measurements in the freeze-out state of central Si+Si coll…
Examining an Image Reconstruction Method in Infrared Emission Tomography
Loizos Koutsantonis, Aristotelis-Nikolaos Rapsomanikis, Efstathios Stiliaris +1
We present and evaluate the application of the "Reconstructed Image from Simulations Ensemble" (RISE), a novel tomographic image reconstruction method, in infrared tomography. We d…
