Hemodynamic profile of two aortic endografts accounting for their postimplantation position
(2017)Endovascular aneurysm repair (EVAR) is a clinically effective technique for treating anatomically eligible abdominal aortic aneurysms (AAAs), involving the deployment of an endograft (EG) that is designed to prevent blood ... -
Information content in nuclear medicine imaging
(2019)The aim of the present study was to investigate the information content of positron emission tomography (PET) images. We used the GATE Monte Carlo package (GEANT4 application for tomographic emission) and reconstructed ... -
Lightweight steganalysis based on image reconstruction and lead digit distribution analysis
(2011)This paper presents a novel method of JPEG image Steganalysis, driven by the need for a quick and accurate identification of stego-carriers from a collection of files, where there is no knowledge of the steganography ... -
Sub-Sampled Time Domain Sparse Information in Wired OFDM and STBC-OFDM Systems
(2022)A sub-sampling method developed for wired or wireless Orthogonal Frequency Division Multiplexing (OFDM) systems is presented. The proposed technique can be activated during the exchange of sparse data. The sub-sampling ... -
Tomographic Image Reconstruction with a Spatially Varying Gamma Mixture Prior
(2018)A spatially varying Gamma mixture model prior is employed for tomographic image reconstruction, ensuring effective noise elimination and the preservation of region boundaries. We define a line process, modeling edges between ...
