The widespread use of echocardiography has generated considerable interest in the
ultrasonic properties of myocardial collagen. This study was designed to investigate the …

This study investigates the influence of the fiber‐reinforced nature of myocardium and
tendon on the propagation of transverse mode ultrasonic waves. Formalin fixed specimens …

Recent studies from our laboratory have detailed the anisotropy of velocity of
quasilongitudinal‐mode ultrasonic waves through formalin fixed samples of normal human …

Measurements of ultrasonic quasilongitudinal velocity were made in the muscle fiber plane
of excised human myocardium. Multiple adjacent planes across the left ventricular wall were …

The content and organization of collagen in the cardiac interstitium may represent significant
determinants of the ultrasonic scattering properties of myocardium. This study was designed …

The linear elastic properties of a soft tissue exhibiting a unidirectional arrangement of
reinforcing fibers may be described in terms of the five independent elastic stiffness …

Fibrous tissue on conventional ultrasound images appears as an echo-bright area. We have
observed that on high-frequency ultrasonography images of thin sections of myocardium …

This study was designed to measure the ultrasonic attenuation within phantoms and tissue
samples over a broad bandwidth and at many angles of incidence with respect to intrinsic …

Clinical implementation of quantitative ultrasonic tissue characterization is likely to require
imaging the heart with sound propagating at varying angles relative to the fibers of the heart …

Anisotropy is a characteristic of ultrasonic backscatter observed in a number of materials
containing directionally oriented fibers. It has been hypothesized that in heart the fibrous …
