Parameter optimization of pulse compression in ultrasound imaging systems with coded excitation
Ultrasonic imaging Coded excitation Pulse compression
2010/1/6
A linear array imaging system with coded excitation is considered, where the proposed excitation/compression scheme maximizesthe signal-to-noise ratio (SNR) and minimizes sidelobes at the output of th...
A new method of ultrasound color flow mapping
Doppler processing Autocorrelation Ultrasound simulation
2010/1/6
Conventional ultrasound color flow mapping systems estimate and visualize only the axial velocity component. To obtain thetransverse velocity component a modification of a multiple-beam method is prop...
A High-Resolution Technique for Ultrasound Harmonic Imaging Using Sparse Representations in Gabor Frames
Gabor frames harmonic imaging sparse representations
2010/1/6
Over the last few decades there were dramatic
improvements in ultrasound imaging quality with the utilization
of harmonic frequencies induced by both tissue and echo-contrast
agents. The advantages...
Robust Estimation of Ultrasound Pulses Using Outlier-Resistant De-Noising
Outlier-resistant estimation ultrasound pulse estimation
2010/1/6
A different approach to the problem of estimation of
the ultrasound pulse spectrum, which usually arises as a part of
ultrasound image restoration algorithms, is presented. It is shown
that this es...
Implications of 2D Ultrasound Findings of the Scrotum in Asymptomatic Microfilaria Carriers of Wuchereria bancrofti Infection
Night blood survey W.bancrofti filariasis hydrocele
2010/12/10
The incubation period of lymphatic filarial disease is long, and a large proportion of individuals infected with W. bancrofti are asymptomatic. In India, the most common presenting clinical manifestat...
MR thermometry characterization of a hyperthermia ultrasound array designed using the k-space computational method
MR thermometry characterization a hyperthermia ultrasound array the k-space computational method
2010/2/26
Unlike conventional computational methods, the k-space method provides a powerful tool to predict pressure wavefield in large scale, 3D, inhomogeneous and coarse grid tissue models. Noninvasive MRI th...
Application of Static Pressure Change in Estimation of Elastic Parameters of Rabbit’s Artery by Doppler Ultrasound
Doppler ultrasound static pressure change elastic parameters carotidartery
2010/2/4
Backgrounds/Objectives : Noninvasive evaluation of elastic properties of vessel wall is hampered by the absence of methods to directly asse ss local elasticity. In order to invasively record the stati...
Non-rigid registration of a 3D ultrasound and a MR image data set of the female pelvic floor using a biomechanical model
a 3D ultrasound and a MR image data the female pelvic floor a biomechanical model
2010/3/1
The morphology is of special interest in the assessment of anal incontinence and the non-rigid registration of normal clinical MR and US image data sets is a new field of the adaptation of this method...
