Three-dimensional diffuser and three-dimensional speckles
Technical Physics, 1998The well-known model of a diffusely scattering surface as a set of randomly distributed point scatterers is generalized to the case of a volume diffuser. Assuming that the coordinates of the coherent radiation source, the observer, and also the diffuser shape are arbitrary, a formula is obtained for the spatial correlation function of the scattered ...

Three-dimensional echocardiography
Heart, 2009Over the past two to three decades echocardiography has come a considerable distance from the early M-mode machines, and has become an indispensable diagnostic tool in any cardiovascular department. It has long been proved to be safe and cost-effective, and its clinical versatility has steadily increased with the continued integration of newer ...

This chapter deals with perhaps the most difficult task of conceptualising 3D form and space. First, I examine the constituent parts of 3D form, and then I unfold what a person registers in sequence when entering a space. Light defines how a space is seen, by reflecting off surfaces and form. Design is about expression of identity and 3D form will play

Three-dimensional echoventriculography
American Heart Journal, 1983A method of generating a three-dimensional image of the human left ventricle by computer techniques is described. The volume of each image was estimated by a modification of Simpson's rule. The method was applied to nine suitable patients and estimations of end-diastolic and end-systolic volumes were compared to volumes determined by cineangiography ...

Three-Dimensional Photoelasticity
Journal of Applied Physics, 1951The classical Sommerfeld-Runge method for deriving the laws of geometric optics in isotropic inhomogeneous media from Maxwell's equations is applied to problems in ``weakly'' anisotropic and inhomogeneous media. This leads to a generalized Hamilton-Jacobi partial differential equation for the phases of the two waves (eikonals) which can propagate with ...

“Three-Dimensional” ultramicrotomy
Journal of Ultrastructure Research, 1965A method is described for the routine production of ultrathin sections, cut alternately at right angles to each other. Two separate ribbons of sections are obtained, each being the right-angled complement of the other, and they share a common side along their entire length.

Veterinary Record, 2015
After her final year studying veterinary medicine at the Royal Veterinary College (RVC) and before starting an internship, Vicky Simons took on the job of creating a life‐size equine anatomical model ‘anatohorse’ (also known as Geoff)

Three-dimensional echocardiography.
Minerva cardioangiologica, 2005Three-dimensional (3-D) echocardiography has been an important research goal ever since the introduction of two-dimensional (2-D) echocardiography. Most approaches towards 3-D echocardiography were off-line and based on the sequential rotational scanning and acquisition of multiple cross-sectional images together with external or internal reference ...
