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 ...
Dual electrode capacitive micromachined ultrasonic transducer array for 1-D intracardiac echocardiography (ICE)
(American Society of Mechanical Engineers (ASME), 2007)
We designed and fabricated a 64 element 1-D linear dual electrode Capacitive Micromachined Ultrasonic Transducer (CMUT) array operating at 9.5 MHz for Intracardiac Echocardiography (ICE). The dual electrode CMUT structure ...
Micromachined capacitive transducer arrays for intravascular ultrasound
(SPIE, 2005)
Intravascular ultrasound (IVUS) imaging has become an essential imaging modality for the effective diagnosis and treatment of cardiovascular diseases during the past decade enabled by innovative applications of piezoelectric ...
Üç boyutlu akustik görüntüleme için ön alıcı-verici tümdevre
(IEEE, 2004)
Tıbbi ultrasonik görüntüleme sistemleri, genel olarak bir çevirici elemanı ve akustik işaretin üretilip algılanmasından sorumlu elektronik oluşmaktadır. Tek boyutlu dönüştürücü dizileriyle, incelenmekte olan ortamın iki ...
Phased subarray imaging for low-cost, wideband coherent array imaging
(IEEE, 2003)
The front-end hardware complexity of conventional full phased array (FPA) imaging is proportional to the number of array elements. Phased subarray (PSA) imaging has been proposed as a method of reducing the hardware ...
