Design and Evaluation of Phased Array Transducers for Deep Brain Stimulation in Nucleus Accumbens Region of the Rat Brain 

Kilinc, M. Sait; Aydin, M. Akif; Ergün, Arif Şanlı; Bozkurt, Ayhan; Deveci, Erdem (IEEE, 2017-10)
Transcranial focused ultrasound (tFUS) is a novel noninvasive neuromodulation method that has many potential application in the treatment of neuropsychiatric and neurologic disorders. One such application is addiction ...

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 ...

An Open Source, Modular and Scalable HIFU Driver System 

Ozum, H. Emre; Yetik, Hasan; Kilinc, M. Sait; Ergün, Arif Şanlı (IEEE, 2017-10)
High-intensity focused ultrasound (HIFU) have been an attractive research topic for some time now. HIFU studies have started with single-element transducers, but using arrays provide the opportunity to scan the focal point ...

Ultrasonic Transmittance of Rat Skull as a Function of Frequency 

Aydin, M. Akif; Kilinc, M. Sait; Ergün, Arif Şanlı; Bozkurt, Ayhan; Deveci, Erdem (IEEE, 2016)
The applications of focused ultrasound in the brain have the common obstacle of penetrating the skull. The purpose of this study is to characterize the ultrasonic transmittance of the rat skull, which is the common animal ...

An Integrated Beamforming Driver for CMUT based Ultrasound Catheter Ablation System 

Yetik, Hasan; Ergün, Arif Şanlı; Bozkurt, Ayhan (IEEE, 2014-10)
In CMUT based ultrasound catheter ablation systems, transducer arrays and their drivers are to be kept as small as possible due to size restrictions, while maintaining a reasonable number of channels for proper beamforming. ...

Multiphase gan class-d resonant amplifier for high-intensity focused ultrasound 

Gu, L.; Stedman, Q.; Rasmussen, M.; Pai, C.-N.; Brenner, K.; Ma, B.; Ergün, Arif Şanlı; Khuri-Yakub, B.; Davila, J.R. ( Institute of Electrical and Electronics Engineers Inc., 2019)
Focused ultrasound treats tissue deep in the body without damaging surrounding structures. Driven by large-Amplitude RF electrical signals, ultrasonic transducers can generate large pressure acoustic wave. Wide-bandgap ...

Portable Low Cost Ultrasound Imaging System 

Sobhani, M. Rahim; Ozum, H. E.; Yaralioglu, G. G.; Ergün, Arif Şanlı; Bozkurt, A. (IEEE, 2016)
The applications of ultrasound in medicine have been increasing in the last decade either in diagnostics or in treatments. Ultrasound is routinely used in clinical examinations, such as pregnancy exams. On the other hand, ...

Frequency Optimization in High Intensity Focused Ultrasound 

Yetik, Hasan; Ariyurek, Cemre; Bozkurt, Ayhan; Ergün, Arif Şanlı (IEEE, 2014-10)
In high intensity focused ultrasound (HIFU) the choice of transducer frequency depends on the target depth and tissue type. At high frequencies attenuation does not permit enough acoustical power to be transmitted to the ...
Thumbnail

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 ...
Thumbnail

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 ...
