Beamforming and hardware design for a multichannel front-end integrated circuit for real-time 3D catheter-based ultrasonic imaging
(SPIE-Int Soc Optical Engineering, 2006)
We are working on integrating front-end electronics with the ultrasound transducer array for real-time 3D ultrasound imaging systems. We achieve this integration by flip-chip bonding a two-dimensional transducer array to ...
Volumetric imaging using fan-beam scanning with reduced redundancy 2D arrays
(IEEE, 2006)
Phased array processing with a fully populated 2D array produces the best image quality but requires excessive number of active parallel front-end channels. Here we explore four array designs with reduced redundancy in ...
H.264 video kodlamada çerçeve seviyesinde karmaşıklık kontrolü
(IEEE, 2007)
H.264 kodlama standardı, değişken blok boyutlu makroblok bölüntüleri kullanan çok sayıda farklı çerçeveler arası kestirim kipini desteklemektedir. Ne var ki, her olası bölüntü için eniyi devinim vektörlerini aramanın ...
Annular CMUT arrays for side looking intravascular ultrasound imaging
(IEEE, 2007)
Although side looking intravascular ultrasound (SL-IVUS) imaging systems using single element piezoelectric transducers set the resolution standard in the assessment of the extent of coronary artery disease, improvements ...
Cluster based sensor scheduling in a target tracking application with particle filtering
(IEEE, 2007)
In multi-sensor applications management of sensors is necessary for the classification of data they produce and for the efficient use of sensors as well. One of the important aspects in sensor management is the sensor ...
A new algorithm for high speed speech and audio coding
(IEEE, 2007)
In this work, a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ...
Forward-looking IVUS imaging using a dual-annular ring CMUT array: Experimental results
(IEEE, 2007)
This paper presents the experimental results on forward-looking Intravascular ultrasound (FL-IVUS) using dual-annular-ring CMUT arrays. The array has a diameter of 1mm including bondpads which consists of separate, concentric ...
An algorithm and its architecture for half-pixel variable block size motion estimation
(IEEE, 2007)
This paper presents an accurate half-pixel variable block size motion estimation algorithm and its hardware architecture. The proposed algorithm does not require interpolation of the reference frame pixels and has near ...
An integrated circuit with transmit beamforming and parallel receive channels for 3D ultrasound imaging: testing and characterization
(IEEE, 2007)
The cost and complexity of medical ultrasound imaging systems can be reduced by integrating the transducer array with an integrated circuit (IC). By incorporating some of the system's front-end electronics into an IC, bulky ...
A novel fast algorithm for speech and audio coding
(IEEE, 2007)
In this work a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ...
