      A Comparison of Ultrasound Intima-Media Thickness Measurements of the Left and Right Common Carotid Artery 

      Loizou, Christos P.; Nicolaïdes, Andrew N.; Kyriacou, Efthyvoulos C.; Georghiou, N.; Griffin, Maura B.; Pattichis, Constantinos S. (2015)
      The intima-media thickness (IMT) of the common carotid artery (CCA) is an established indicator of cardiovascular disease (CVD). There have been reports about the difference between the left and the right sides of the CCA ...

      Effect of zooming on texture features of ultrasonic images 

      Kakkos, Stavros K.; Nicolaïdes, Andrew N.; Kyriacou, Efthyvoulos C.; Pattichis, Constantinos S.; Geroulakos, George (2006)
      Background: Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have ...

      Snakes based segmentation of the common carotid artery intima media 

      Loizou, Christos P.; Pattichis, Constantinos S.; Pantzaris, Marios C.; Tyllis, Theodosis K.; Nicolaïdes, Andrew N. (2007)
      Ultrasound measurements of the human carotid artery walls are conventionally obtained by manually tracing interfaces between tissue layers. In this study we present a snakes segmentation technique for detecting the ...

      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 ...

      Ultrasound image quality evaluation 

      Loizou, Christos P.; Pattichis, Constantinos S.; Istepanian, Robert Sh Habib; Pantzaris, Marios C.; Kyriacou, Efthyvoulos C.; Tyllis, Theodosis K.; Nicolaïdes, Andrew N. (Institute of Electrical and Electronics Engineers Inc., 2003)
      The objective of this work was to evaluate the image quality of two different ultrasound image scanners before and after de-speckle filtering. The evaluation was made by statistical and texture analysis, as well as by ...
