Three-dimensional echocardiography
Current Opinion in Cardiology, 1998Three-dimensional echocardiography depicts the heart and its structures in their realistic forms. This capability decreases variability both in the quality and the interpretation of complex pathology, among investigators. Therefore, it is likely that the method will become the standard echocardiography examination in the future.

Acta Oto-Laryngologica, 1994
We used a three-dimensional audiogram which displays duration of the disease on the X-axis, frequency on the Y-axis, and hearing level on the Z-axis, to aid observation of hearing changes during the course of various otologic diseases. An overall, quantitative view of the changes in a patient's hearing level with time was easily obtainable with this ...

Applied Optics, 1988
This paper describes the optical and control principles of a newly developed three-dimensional optometer (TDO). The TDO makes it possible to measure simultaneously three basic ocular responses in an actual work situation: accommodation; eye movement; and pupil area.

THREE DIMENSIONAL ROENTGENOGRAPHY
American Journal of Roentgenology, 1969A technique for producing a three-dimensional image of an object from a set of roentgenograms has been demonstrated. N individual roentgenograms, taken from different directions, are combined in a simple optical system producing a real image of the object in space.

Three-dimensional modes of three-dimensional microlasers
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017On-chip photonic devices are often considered in the framework of a two-dimensional (2D) approximation, with light propagating within a defined horizontal plane. Nethertheless, the finite cavity thickness plays an important role in understanding relevant three-dimensional (3D) effects. For instance, the light propagating in the device is diffracted and

Surgical Endoscopy, 1996
Laparoendoscopic surgery is fueled by technology, and advances in medical imaging may bring about further progress. The application of three-dimensional ultrasound to minimally invasive surgery represents technology "just over the horizon." This article describes the scientific basis of three-dimensional ultrasound and its ability "to see" anatomy not ...

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 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 ...
