Ring array processing for forward-looking intravascular and intracardiac ultrasonic imaging
(Işık Üniversitesi, 2010-06-08)
Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in IVUS and ICE applications. One of the main challenges in the array based FLIVUS systems is the large channel count which ...
Tıbbi ultrasonik kanal içi görüntüleme için yeni yöntemler
(Tübitak, 2008-09)
Yakın zamanda yapılan çalışmalarımızdaki yaklaşımda, aktif kanal sayısını azaltmak için fazlalık (redundant) gönderme-alma eleman ikilileri azalırken gerekli olan (non-redundant) gönderme-alma eleman ikilileri korunmaktadır. ...
Implementation of a fixed cellular terminal with mobile phone
(Işık Üniversitesi, 2002-09)
The thesis reports the design and realization of a fixed cellular terminal (FCT) device which works with a mobile phone as a GSM Module. The design is emphasized at the structure not to be complex and suitable to be used ...
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 ...
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 ...
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 ...
Experimental study of dual-ring CMUT array optimization for forward-looking IVUS
(IEEE, 2011)
Forward-looking (FL) catheters have guiding and volumetric imaging capacities which are highly desirable for IVUS applications. Large channel and firing counts have to be reduced to enable 3-D real-time imaging and simplify ...
An Analog beamformer for integrated high-frequency medical ultrasound imaging
(IEEE, 2011)
We designed and fabricated a dynamic receive beamforming integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer is suitable for integration with an ultrasound annular array for high-frequency (30-50 MHz) ...
Optimizing circular ring arrays for forward-looking IVUS imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2011-12)
Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) applications. One of the main challenges of array-based FL-IVUS systems is the large ...
Co-array optimization of CMUT arrays for forward-looking IVUS
(IEEE, 2009-09)
The ring annular array structure is a preferred configuration for implementing Forward-Looking IVUS (FLIVUS) catheters as it allows for volumetric imaging as well as use of a guidewire at the center. CMUT technology is ...
