      Dose-dependent artifact in the far wall of the carotid artery at dynamic contrast-enhanced US 

      Thapar, A.; Shalhoub, J.; AVERKIOU, MICHALAKIS A.; Mannaris, C.; Davies, A. H.; Leen, E. L.; Thapar, Ankur; Shalhoub, Joseph; AVERKIOU, MICHALAKIS A.; Mannaris, Christophoros; Davies, A. H.; Leen, Edward L. S. (2012)
      Purpose: To quantify a pseudoenhancement phenomenon observed during dynamic contrast material-enhanced ultrasonography (US) of the carotid artery, both in vitro and in vivo.Materials and Methods: Ethical approval was ...

      Improvement of the accuracy of liver lesion DCEUS quantification with the use of automatic respiratory gating 

      Christofides, Damianos; Leen, Edward; Averkiou, Michalakis A.; Leen, Edward L. S.; Averkiou, Michalakis A. (2016)
      Objectives: To evaluate the efficiency of automatic respiratory gating (ARG) in reducing respiratory motion-induced artefacts from dynamic contrast-enhanced ultrasound (DCEUS) acquisitions and to assess the impact of ARG ...

      Probabilistic approaches to fault detection in networked discrete event systems 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2005)
      In this paper, we consider distributed systems that can be modeled as finite state machines with known behavior under fault-free conditions, and we study the detection of a general class of faults that manifest themselves ...

      Robust and efficient ultrasound video coding in noisy channels using H.264. 

      Panayides, Andreas S.; Pattichis, Marios S.; Pattichis, Constantinos S.; Loizou, Christos P.; Pantzaris, Marios C.; Pitsillides, Andreas (2009)
      In this paper we define diagnostic Regions of Interest (ROIs) for carotid ultrasound medical video, which we then use as input for Flexible Macroblock Ordering (FMO) slice encoding. We extend the FMO concept by enabling ...

      A standardised protocol for texture feature analysis of endoscopic images in gynaecological cancer 

      Neofytou, Marios S.; Tanos, Vasilios; Pattichis, Marios S.; Pattichis, Constantinos S.; Kyriacou, Efthyvoulos C.; Koutsouris, Demetrios Dionysios (2007)
      Background: In the development of tissue classification methods, classifiers rely on significant differences between texture features extracted from normal and abnormal regions. Yet, significant differences can arise due ...
