High frequency imaging probes have been widely used in minimally invasive catheter-based applications especially for intravascular ultrasound (IVUS) and intracardiac echocardiography (ICE) imaging. Although there are commercially available imaging catheters which can provide 2-D sector images of the internal heart structures, their utility could be significantly expanded with the realization of real time 3-D field of view. The implementation of such microscale systems using hundreds of transducer elements require advanced transducer technology and high integration capabilities. We have been developing technologies for integration of capacitive micromachined ultrasonic transducer (CMUT) arrays and custom designed CMOS front-end electronics on the same silicon chip for ultimately miniaturized ultrasound systems for 3-D IVUS and ICE imaging. In this talk, I will give an overview of the current challenges in these applications and present the technologies and methods that we are developing in our research lab in terms of monolithic transducer-electronics integration and massive channel reduction for the implementation of these systems.


Coskun Tekes is a Research Engineer in Micromachined Sensors and Transdcuers (MiST) group in the Mechanical Engineering department at Georgia Institute of Technology. He graduated from Istanbul Technical University in Electrical Engineering and received his Ph.D. in Electronics Engineering from Isik University in Turkey in 2010. After graduation, he joined the MiST group as a postdoctoral fellow working on several NIH funded projects. His research interests include medical ultrasound imaging, array signal processing and micromachined transducers.
