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 ...
Modelling ultrasonic sensor for gas bubble profiles characterization of chemical column
(Elsevier B.V., 2013)
In this paper, we present a modelling and experimental work to characterize gas bubble profiles in chemical column using a pair of ultrasonic sensor. The gas bubble profiles from 2.90 mm to 7.50 mm diameter are of interest ...
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 ...
