      De-speckle filtering in ultrasound imaging of the carotid artery 

      Christodoulou, Christodoulos I.; Loizou, Christos P.; Pattichis, Constantinos S.; Pantzaris, Marios C.; Kyriacou, Efthyvoulos C.; Pattichis, Marios S.; Schizas, Christos N.; Nicolaïdes, Andrew N. (2002)
      The main objective of this paper is to evaluate the classification performance of de-speckle filtering on ultrasound imaging of the carotid atherosclerotic plaque. The following procedure was investigated on 230 images ...

      Despeckle filtering of ultrasound images 

      Loizou, Christos P.; Pattichis, Constantinos S. (Springer New York, 2011)
      It is well known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. This necessitates the need for robust despeckling techniques for both routine clinical practice and ...

      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 ...
