Ultrasound is now a clinically accepted modality in the management of osteoporosis. The
most common commercial clinical devices assess fracture risk from measurements of …

Although it has been more than 20 years since the first recorded use of a quantitative
ultrasound (QUS) technology to predict bone fragility, the field has not yet reached its …

Speckle noise is an inherent property of medical ultrasound imaging, and it generally tends
to reduce the image resolution and contrast, thereby reducing the diagnostic value of this …

The problem of reconstruction of ultrasound images by means of blind deconvolution has
long been recognized as one of the central problems in medical ultrasound imaging. In this …

From an acoustical point of view, bone is a complex medium as it is heterogeneous,
anisotropic and viscoelastic. This chapter reviews the basic notions of physical acoustics …

The finite frequency bandwidth of ultrasound transducers and the nonnegligible width of
transmitted acoustic beams are the most significant factors that limit the resolution of medical …

Ultrasound beams propagating in biological tissues undergo distortions due to local
inhomogeneities of the acoustic parameters and the nonlinearity of the medium. The …

This paper reviews theory, measurements, and computer simulations of scattering from
cancellous bone reported by many laboratories. Three theoretical models (binary mixture …

The present study was designed to assess the relationships between QUS parameters and
bone density or microarchitecture on samples of human femoral trabecular bone. The …

Adjuvant therapies that lower the thrombolytic dose or increase its efficacy would represent
a significant breakthrough in the treatment of patients with ischemic stroke. The objective of …
