Tomography computer-aided

The grade determines whether the mica can be used in high technology elecironic instruments, e.g.. computer-aided tomography (CATl scan, or in low technology devices, e.g.. a toaster. Many types of insulators, as well as the base for electronic circuits, are formed from the high quality sheets of mica by a punch pressing operation. 

CT represents Computer-aided Tomography the computer reconstructs a series of measured images of tissue density (tomography). Small differences in tissue density may indicate the presence of a tumor.

The first model proposed for approximated analysis of the left ventricle of the heart was a spherical shell (Pao, 1980a and Mirsky, 1974) which was adopted by Woods in 1892 so that the Laplace law could be applied for calculation of the wall stresses. When the biplane silhouettes can be obtained by the X-ray technique, the left ventricle has since been analyzed as axisymmetric thick-walled shells. The advances in computer-aided tomography in recent years make it possible to image and reconstruct the cross-sectional shapes of the heart (Ritman, 1983). As a result of this development, the true three-dimensional structural shape of the heart can be accurately formed by stacking of the reconstructed cross sections together. Various finite element models have been proposed (Figure 1) for the analyses of the ventricles as well as for the cardiac valves both natural and prothetic (Pao,...
