The known fishes fall into rather sharply defined taxa, the relations of which are not altogether clear. The earliest group, the heterostracans, appears in the

The book is now inevitably longer, but its scope remains the same and the original approach has been main­ tained as far as possible. I have, however, undertaken a certain amount ofre­ arra

Basic Principles of Tomography,raphic image can obtained from its measurements using two simple examples. The concept of projection is then explained. Next, the filtered backprojection image reconstruction method is introduced using a point source example. Finally, the concept of backprojection is discussed.

Parallel-Beam Image Reconstruction,he Fourier domain. From this theorem, many image reconstruction algorithms are derived. Among these algorithms, the filtered backprojection (FBP) algorithm is the most popular one, which consists of a ramp-filtering step and a backprojection step. The filtering can be implemented as a multiplication

Fan-Beam Image Reconstruction,not along parallel lines, the image reconstruction algorithms presented in Chapter 2 cannot be applied directly. This chapter uses the flat detector and curved detector fan-beam imaging geometries to illustrate how a parallelbeam reconstruction algorithm can be converted to user’s imaging geometry f

叙述

Transmission and Emission Tomography,a. If the radiation sources are inside the patient, the imaging system acquires the emission data. For transmission scans, the image to be obtained is a map (or distribution) of the attenuation coefficients inside the patient. For the emission scans, the image to be obtained is the distribution of t
