Publisher Summary This chapter reviews linear tomographic movement. It is noticed that in this tomographic movement the focal spot moves along a line parallel to the film movement. During this movement, the X-ray tube is itself rotated about the focus as axis in order to keep the beam directed at the film and so achieve uniform exposure rate during ...

Tomography is traditionally associated with medical ‘CT’ scanners that have been in use for over 30 years now. This mathematical concept is now applied widely by scientists and engineers in a variety of measurements involving solids, fluid, gases and plasmas.

Relation between computed tomography and diffraction tomography
Journal of the Optical Society of America A, 2001The relationship between computed tomography (CAT) and diffraction tomography (DT) is investigated. A simple condition with a clear physical meaning is derived for the applicability of CAT. Corrections due to scattering are incorporated into CAT, and it is shown that the effect of scattering may be characterized by a two-dimensional fractional Fourier ...

The machine whirs and clicks from slice to slice, as thetechnician watches through a shielded window and theimmobile patient moves on a pallet through a series ofstations. The mass of data from this exercise goes to afast computer and is integrated into detailed cross sec-tions in three dimensions.

Quantitative computed tomography
Radiologic Clinics of North America, 2003Unlike dual x-ray absorptiometry and high-resolution CT scan and MR imaging techniques, which are largely restricted to the peripheral skeleton owing to radiation dose and signal-to-noise considerations, volumetric quantitative measures provide measures of cortical and trabecular volumetric bone mineral density, cross-sectional geometry, and estimates ...
