Journal ArticleDOI
Doppler ultrasound signal denoising based on wavelet frames
TL;DR: It was concluded that the performance of this discrete wavelet frame (DWF) approach is higher than that of the standard (critically sampled) wavelet transform (DWT) for the Doppler ultrasound signal denoising.
Journal ArticleDOI
Measurement of the Dispersion and Attenuation of Cylindrical Ultrasonic Guided Waves in Long Bone
TL;DR: Cylindrical guided waves of low-frequency and low-order have been shown to demonstrate more dispersion and less attenuation and should, therefore, be used to evaluate long bone.
Journal ArticleDOI
Analysis of frequency dependence of ultrasonic backscatter coefficient in cancellous bone
TL;DR: It is demonstrated that BSC is a nonlinear function of frequency and increases with frequency, and the status of cancellous bone and the degree of osteoporotic fracture risk may be assessed.
Journal ArticleDOI
Estimating coronary artery lumen area with optimization-based contour detection
TL;DR: A modified optimization-based contour detection method was presented to compute the lumen area of the coronary artery from intravascular ultrasound (IVUS) video images, using a novel form of the external energy which combines the gradient and variance of the intensity of image in the radial direction.
Journal ArticleDOI
Simplified inverse filter tracking algorithm for estimating the mean trabecular bone spacing
TL;DR: The study demonstrates that the SIFT algorithm has the potential to be a reliable and robust method for the estimation of MTBS in the presence of a small signal-to-noise ratio, a large spacing variation between regular scatterers, and a large scattering strength ratio of diffuse scatterer to regular ones.
