    • Absolute temperature monitoring using RF radiometry in the MRI scanner 

      El-Sharkawy, A.-M. M.; Sotiriadis, P. P.; Bottomley, P. A.; Atalar, Ergin (Institute of Electrical and Electronics Engineers, 2006)
      Temperature detection using microwave radiometry has proven value for noninvasively measuring the absolute temperature of tissues inside the body. However, current clinical radiometers operate in the gigahertz range, which ...
    • Exceptional adaptable MWIR thermal emission for ordinary objects covered with thin VO2 film 

      Durna, Yılmaz; Kocer, Hasan; Aydın, Koray; Cakir, Mehmet Cihan; Soydan, Mahmut Can; Odabasi, Oguz; Işık, Halil; Ozbay, Ekmel (Elsevier Ltd, 2021-01-25)
      Monotonous thermal radiation emitted from an ordinary object can be brought into a dynamic and versatile form that can be shaped according to the application area with the ingenious design of the surface coatings. Building ...
    • Simultaneous radiofrequency (RF) heating and magnetic resonance (MR) thermal mapping using an intravascular MR imaging/RF heating system 

      Qiu, B.; El-Sharkawy, A.-M.; Paliwal, V.; Karmarkar, P.; Gao, F.; Atalar, Ergin; Yang, X. (John Wiley & Sons, 2005-06)
      Previous studies have confirmed the possibility of using an intravascular MR imaging guidewire (MRIG) as a heating source to enhance vascular gene transfection/expression. This motivated us to develop a new intravascular ...
    • SSFP-based MR thermometry 

      Paliwal, V.; El-Sharkawy, A.-M.; Du, X.; Yang, X.; Atalar, Ergin (John Wiley & Sons, 2004)
      Of the various techniques employed to quantify temperature changes by MR, proton resonance frequency (PRF) shift-based phase-difference imaging (PDI) is the most accurate and widely used. However, PDI is associated with ...
