New Direction of Biplane Transesophageal Echocardiography with Special Emphasis on Real‐Time Biplane Imaging and Matrix Phased‐Array Biplane Transducer

Echocardiography, 1990
This article reports on the technical aspects of an online real‐time biplane transesophageal echocardiographic imaging system and of a single‐matrix, phased‐array transducer capable of transverse and longitudinal scanning.

Biplanes and near biplanes

Journal of Geometry, 1991
The authors produce an infinite class of combinatorial objects which they call near biplanes. A near biplane is defined as follows: it is a square 1-design with the property that its \(V\times V\) incidence matrix satisfies (i) the inner product of any two distinct rows is 0, 2 or 4; (ii) for any fixed row the sum of the inner products with the ...

Value of Biplane Splenoportography

Radiology, 1963
Splenoportography is a useful technic in the evaluation of a variety of diagnostic problems (1, 2). Our procedure differs basically in no significant way from that of Ruzicka and Rousselot's group (3). In view of the difficulty experienced in interpreting some of 100 splenoportograms in the anteroposterior views, however, biplane studies were added in ...

Biplane ventriculography in the rat

American Journal of Physiology-Heart and Circulatory Physiology, 1986
Biplane ventriculography was performed on nine intact anesthetized rats. Images of the left ventricle large enough for analysis were obtained by placing the rats close to the radiographic tubes (direct enlargement). Sampling rates, adequate for heart rates of 500 beats/min, were obtained by filming at 500 frames/s.

Biplane Cine-Angiocardiography

Australasian Radiology, 1962
Summary A practical method of biplane cine-angio-cardiography is described and its advantages are enumerated. The method has worked g satisfactorily and no unexpected problems have arisen.

Topological Homology Semi-Biplanes

Monatshefte f�r Mathematik, 2001
A semi-biplane is an incidence structure where each pair of points is incident with either \(0\) or \(2\)~blocks, and dually. In order to avoid anomalies one further requires that the incidence graph is connected and that the usual richness conditions are satisfied.
