Biometric identification using fingertip electrocardiogram signals
(Springer London Ltd, 2018-07)In this research work, we present a newly fingertip electrocardiogram (ECG) data acquisition device capable of recording the lead-1 ECG signal through the right- and left-hand thumb fingers. The proposed device is ... -
Critical behavior of thermal phase transitions of iota-carrageenan in CaCl2 solution
(Elsevier B.V., 2006-07-15)In situ photon transmission method was applied to study thermal phase transitions of ?-carrageenan in CaCl2 solution. Coil-to-helix (c-h) and helix-to-dimer (h-d) transitions were detected upon cooling. An extra dimer-to-dimer ... -
Damar içi öne bakan ultrasonik görüntüleme için eşdeğer dizi örnekleme yöntemleri
(IEEE, 2009-06-26)Damar içi öne bakan ultrasonik görüntüleme gerçek zamanlı hacimsel (üç boyutlu) görüntülemeye imkan vermesi bakımından yaygın olarak kullanılmaktadır. Damar içi görüntülemede fiziksel boyutların küçük olması nedeniyle ... -
Dual-annular-ring CMUT array for forward-looking IVUS imaging
(IEEE, 2006)We investigate a dual-annular-ring CMUT array configuration for forward-looking intravascular ultrasound (FL-IVUS) imaging. The array consists of separate, concentric transmit and receive ring arrays built on the same ... -
An endoscopie imaging system based on a two-dimensional CMUT array: real-time imaging results
(IEEE, 2005)Real-time catheter-based ultrasound imaging tools are needed for diagnosis and image-guided procedures. The continued development of these tools is partially limited by the difficulty of fabricating two-dimensional array ... -
A factorized high dimensional model representation on the nodes of a finite hyperprismatic regular grid
(Elsevier Science inc, 2005-05-25)When the values of a multivariate function f(x(1),...,x(N)), having N independent variables like x(1),...,x(N) are given at the nodes of a cartesian, product set in the space of the independent variables and ail interpolation ... -
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 ... -
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
(IEEE, 2004)This paper describes the development of an ultrasonic imaging system based on a two-dimensional capacitive micromachined ultrasonic transducer (CMUT) array. The transducer array and front-end electronics are designed to ... -
Subarray delta-sigma beamforming for ultrasonic imaging
(IEEE, 2002)We present a beamforming architecture based on subarray processing with non-uniform oversampling 1-bit delta-sigma (??) modulation. The subarray processing combines conventional phased array and synthetic aperture approaches ... -
Volumetric imaging using 2D capacitive micromachined ultrasonic transducer arrays (CMUTs): Initial results
(IEEE, 2002)This paper presents the first volumetric images obtained using a 2D CMUT array with through-wafer via interconnects. An 8×16-element portion of a 32×64-element array flip-chip bonded onto a glass fanout chip was used in ...
