  • An analog integrated circuit beamformer for high-frequency medical ultrasound imaging 

    Gürün, Gökçe; Zahorian, Jaime S.; Şişman, Alper; Karaman, Mustafa; Hasler, Paul E.; Değertekin, F. Levent (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2012-10)
    We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
  • Monolithic cmut-on-cmos integration for intravascular ultrasound applications 

    Zahorian, Jaime S.; Hochman, Michael; Xu, Toby; Satır, Sarp; Gürün, Gökçe; Karaman, Mustafa; Değertekin, F. Levent (EEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011-12)
    One of the most important promises of capacitive micromachined ultrasonic transducer (CMUT) technology is integration with electronics. This approach is required to minimize the parasitic capacitances in the receive mode, ...
  • Optimizing circular ring arrays for forward-looking ivus imaging 

    Tekeş, Coşkun; Karaman, Mustafa; Değertekin, F. Levent (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011-12)
    Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) applications. One of the main challenges of array-based FL-IVUS systems is the large ...
