CMUT-based volumetric ultrasonic imaging array design for forward looking ICE and IVUS applications
(SPIE-Int Soc Optical Engineering, 2013)
Designing a mechanically flexible catheter based volumetric ultrasonic imaging device for intravascular and intracardiac imaging is challenging due to small transducer area and limited number of cables. With a few parallel ...
A frequency tunable broadband amplifier utilizing tunable capacitors and inductors
(2013)
Software Defined Radio (SDR) technology aims employing commercial communication standards within a single transceiver unit. Therefore, the design of broadband frequency tunable microwave components; particularly tunable ...
Realization of preprocessing blocks of CNN based CASA system on FPGA
(2013)
In this paper, hardware optimization of the preprocessing part of a computer aided semen analysis (CASA) system is proposed, which is also implemented on an FPGA device as a working prototype. A real-time cellular neural ...

Occlusion aware motion compensation for video frame rate up-conversion
(2010)
Since the emergence of high definition (HD) display technologies, video standards conversion problem has become an important issue in storage, transmission and display of video content. Video frame rate up-conversion (FRUC) ...
Kodlayıcı destekli video çerçeve hız artırımı
(IEEE, 2011)
Videoda çerçeve hız artırımı (ÇHA), devinim denkleştirme yöntemlerinin kullanılmasıyla hareketlerin daha keskin ve sürekli gösterimini sağlayarak görsel kaliteyi artırmaktadır. Fakat, devinim kestiriminde karşılaşılan ...
Solid-state SL-IVUS arrays based on non-uniform aperture sampling
(IEEE, 2010)
We propose new reconfigurable ring and cylindrical array designs using non-uniform (Fresnel) aperture sampling with identical differential delays between adjacent elements which reduces the beamformer complexity. For ...
A tunable analog delay element for high-frequency dynamic beamforming
(IEEE, 2009)
Implementing beamforming for high frequency arrays is challenging because of the accurate delay requirements at high frequencies. High frequency digital beamforming is not suitable for catheter based applications as a large ...
Wavelet-based image compression by hierarchical quantization indexing
(IEEE, 2009)
In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet coefficients. A hierarchical classification map is defined in each wavelet subband, which describes the ...
Evaluation of CMUT annular arrays for side-looking IVUS
(IEEE, 2009)
Side-looking (SL) IVUS probes are extensively used for management of cardiovascular diseases. Currently SL-IVUS imaging probes use either a single rotating transducer element or solid-state arrays. Probes with single ...
