Novel adjacent criterion method for improving ultrasonic imaging spatial resolution
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
In this letter, we present a novel approach for improving spatial resolution in ultrasonic tomography. The proposed technique modifies a Back-projection (BP) algorithm in reconstructing tomography images. We used 32-ultrasonic ...
Small gas component detection using ultrasonic transmission-mode tomography system
(Penerbit UTM Press, 2014)
This paper presents the development of an ultrasonic transmission-mode tomography system for the detection of small gas components by using higher frequency ultrasonic transducers. The selection of the transducer is important ...
Gas hold-up profiles measurement using ultrasonic sensor
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ...
