Aesthetic Medicine Cellulite Anti-Cellulite Treatment High Frequency Ultrasound Skin Ultrasound
2013/1/29
The purpose of the research was to evaluate the role of high frequency ultrasound in monitoring and efficacy assessment of anti-cellulite treatments. A group of 66 women used 3 different types of anti...
Ultrasound-Guided Peri-Lymphatic and Peri-Neural Corticosteroid Injection as an Adjuvant to Pain and Lymphedema Management in Terminal Cancer: Two Case Reports
Corticosteroids Adjuvant Cancer Pain Lymphedema Peripheral Nerve Block
2013/1/30
We are reporting two patients presented with intractable cancer pain that was treated with a novel application of an ultrasound-guided peripheral nerve block using corticosteroid. This technique offer...
On the relationship between encapsulated ultrasound contrast agent and pressure
relationship encapsulated ultrasound contrast agent pressure
2010/1/6
Noninvasive measurement of pressure within the heart cavities and other internal organs
(e.g., kidney, liver) has significant clinical value but currently is not feasible. Noninvasive
pressure estim...
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...
Phase Unwrapping for 2-D Blind Deconvolution of Ultrasound Images
Phase unwrapping Poisson equation multiresolution
2010/1/6
In most approaches to the problem of two-dimensional
homomorphic deconvolution of ultrasound images, the estimation
of a corresponding point-spread function (PSF) is necessarily
the first stage in ...
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
