    • Design of a Driver IC for an Ultrasound Catheter Ablation System 

      Bozkurt, Ayhan; Farhanieh, Omid; Roy, Rupak Bardhan; Ergün, Arif Şanlı (IEEE, 2014-10)
      High Intensity Focused Ultrasound (HIFU) is generally administered externally, or through body orifices such as the esophagus, the urethra, the uterus, or the rectum. The devices used in conventional treatment are not ...
    • Embedded Sacrificial Layers for CMUT Fabrication 

      Roy, Rupak B.; Bozkurt, Ayhan; Farhanieh, Omid; Ergün, Arif Şanlı (IEEE, 2015-12)
      Capacitive Micromachined Ultrasonic Transducers (CMUTs) are generally fabricated either by conventional sacrificial release process or by wafer bonding technique. In the former, sacrificial layers are patterned with deposited ...
    • Fabrication of High-Efficiency CMUTs With Reduced Parasitics Using Embedded Metallic Layers 

      Roy, Rupak Bardhan; Farhanieh, Omid; Ergün, Arif Şanlı; Bozkurt, Ayhan (IEEE-Inst Electrical Electronics Engineers Inc, 2017-07-01)
      The transmit and receive sensitivity of the capacitive micromachined ultrasonic transducer (CMUT) is proportional to the active device capacitance formed by the vacuum gap of the device, and an insulation layer between the ...
    • A High Frequency CMUT Ring Array for Small Spot Size HIFU 

      Roy, Rupak Bardhan; Farhanieh, Omid; Ergün, Arif Şanlı; Bozkurt, Ayhan (IEEE, 2016)
      The spot size of HIFU lesion depends on many parameters like size of the transducer, frequency of operation, sonication time etc. A recently developed CMUT based HIFU application for corneal keratoplasty require high ...
