Intravascular ultrasound tissue harmonic imaging in vivo

Martijn E. Frijlink; David E. Goertz; Luc C. a. Van Damme; Rob Krams; Antonius F. W. Van Der Steen IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2006

Tissue harmonic imaging (THI) has been shown to increase image quality of medical ultrasound in the frequency range from 2 to 10 MHz and might, therefore, also be used to improve image quality in intravascular ultrasound (IVUS). In this study we constructed a prototype IVUS system that could operate in both fundamental frequency and second harmonic imaging modes. This system ...


Robust adaptive beamforming: Experimental results

A. B. Gershman; E. Né meth; J. F. Bö hme Signal Processing Conference (EUSIPCO 1998), 9th European, 1998

The performances of adaptive array algorithms are known to degrade in scenarios with moving interfering sources. Recently, several robust approaches have been proposed to overcome this problem. Below, we compare conventional and robust algorithms using shallow sea sonar data with moving co-channel interference originated from shipping noise. This data set was recorded by a towed horizontal Uniform Linear Array (ULA) ...


Theoretical analysis of the sequential lobing technique for correlated targets

Guolong Cui; Antonio De Maio; Luca Pallotta; Alfonso Farina IET Radar, Sonar & Navigation, 2013

This study is focused on the performance analysis of the sequential lobing technique for angle tracking in the presence of correlated fluctuating targets. The evaluation is conducted on the signal at the output of a conventional incoherent receiver followed by a logarithmic amplifier, assuming that the target returns at the two beam positions are correlated random variables. The general expression ...


High productivity multi-sensor seabed mapping sonar for Marine Mineral Resources Exploration

Maxence Rioblanc Acoustics in Underwater Geosciences Symposium (RIO Acoustics), 2013 IEEE/OES, 2013

Marine Mineral Resources Exploration is an emerging activity requiring suitable equipment that will deliver on a timely manner both geo-referenced seabed maps and sub-bottom profiles. The race for deep sea mining has globally started while costs involved have to be minimized at all stages from exploration to exploitation. Building on its 20-year long experience in designing and manufacturing active transducers ...


Sequential Monte Carlo implementation and state extraction of the group probability hypothesis density filter for partly unresolvable group targets-tracking problem

F. Lian; C. -z. Han; W. -f. Liu; X. -x. Yan; H. -y. Zhou IET Radar, Sonar & Navigation, 2010

This study proposes a sequential Monte Carlo (SMC) implementation to the Mahler's group probability hypothesis density filter (PHDF) for partly unresolvable group targets tracking problem. A potential limitation of the group PHDF is that it cannot be used to determine the number of groups. Therefore we have to jointly extract the group number and states from the proposed group SMC-PHDF ...
