      Atomic Force Microscopy Probing of Cancer Cells and Tumor Microenvironment Components 

      Stylianou, A.; Stylianopoulos, T. (2016)
      Cancer cells have different characteristics from normal cells in terms of morphology, cell–cell interactions, cytoskeleton organization, cell growth rates, and cell-extracellular matrix interactions. Although the clarification ...

      Comparative evaluation of despeckle filtering in ultrasound imaging of the carotid artery 

      Loizou, Christos P.; Pattichis, Constantinos S.; Christodoulou, Christodoulos I.; Istepanian, Robert Sh Habib; Pantzaris, Marios C.; Nicolaïdes, Andrew N. (2005)
      It is well-known that speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. The recent advancements in ultrasound instrumentation and portable ultrasound devices necessitate the need ...

      Guest editorial cardiovascular health informatics: Risk screening and intervention 

      Hartley, C. J.; Naghavi, M.; Parodi, O.; Pattichis, Constantinos S.; Poon, C. C. Y.; Zhang, Y. -T (2012)
      Despite enormous efforts to prevent cardiovascular disease (CVD) in the past, it remains the leading cause of death in most countries worldwide. Around two-thirds of these deaths are due to acute events, which frequently ...

      Numerical modeling and experimental studies of light pulse propagation in inhomogeneous random media 

      Madsen, Steen J.; Patterson, Michael S.; Wilson, Brian C.; Jaywant, Satish M.; Othonos, Andreas S. (Publ by Society of Photo-Optical Instrumentation Engineers, 1993)
      The effects of discrete absorbing and scattering objects on light propagation characteristics in random media were examined. Light propagation in the inhomogeneous medium was modeled using a finite difference representation ...

      Quality evaluation of ultrasound imaging in the carotid artery 

      Loizou, Christos P.; Pattichis, Constantinos S.; Istepanian, Robert Sh Habib; Pantzaris, Marios C.; Tyllis, Theodosis K.; Nicolaïdes, Andrew N. (2004)
      Image quality assessment plays an important role in various image-processing applications. In this work we evaluate image quality criteria based on mean square error, signal to noise error, and quality and structural ...

      Quantitative analysis of brain white matter lesions in multiple sclerosis subjects: Preliminary findings 

      Loizou, Christos P.; Pattichis, Constantinos S.; Seimenis, Ioannis; Eracleous, Eleni A.; Schizas, Christos N.; Pantzaris, Marios C. (2008)
      In this study the value of magnetic resonance image (MRI) shape and texture analysis was assessed in multiple sclerosis (MS) subjects, both in differentiating between normal and abnormal tissue and in assessing disease ...

      Subwavelength imaging of an etched fiber with an intracore Bragg grating by apertured photon scanning tunneling microscope 

      Tsai, Din Ping; Chung, Yueh L.; Othonos, Andreas S. (Society of Photo-Optical Instrumentation Engineers, 1995)
      Apertured photon scanning tunneling microscopy (APSTM) was used to image the internal structure of an etched optical fiber with an intracore Bragg grating. Direct evidence of the subwavelength periodic variation of the ...
