Tomographic images

It seems to be expidiently to develop new scanning geometries, which combining with exact reconstruction methods provide high quality of 3D tomographic images. [Pg.219]

In sections, where exists high probability of presence of defects, on the base formed in the binary type of projections acoustical tomographic images of only defective structure elements of sections is restored. IT of restoring stipulates such operations ... [Pg.249]

For restoring of three-dimensional SD is used stated above approach. Under restoring of tomographic images for the base undertakes a function of three-dimensional total image, which after double differentiation and inverse projecting describes sought SD 8 (1) ... [Pg.251]

A 3D summation tomographic image is generated and layers in any direction may be viewed. Image quality is improved by filters. The method has been proved satisfactory on a high radiographic contrast cylindrical object and on more complex items. [Pg.476]

Computerized Tomographic Imaging (CT), a well established method in medical diagnostics for 25 years now, also makes its arrival into non-destructive testing since the last decade. [Pg.492]

The introscopic image of power reactor fuel assembly reveals the presence the fuel elements, the tomographic image reveals their filling by fuel and location. [Pg.602]

Detectors. Two general types of detectors are used in x-ray medical imaging scintillation and gas ionisation. Scintillation detectors are used for both conventional projection and computerized tomographic imaging. Ionization detectors have been used only in CT appHcations. All detectors used in detection of x-ray radiation must be linear and have a maximum efficiency at the wavelength of the x-ray photon to be detected. [Pg.50]

Mag netic Resonance Magnetic resonance imaging (MRI) is a tomographic imaging modaHty. The basis of MRI, equation 6,... [Pg.54]
