Abstract

Successful, modern medical imaging is possible thanks to high-speed digital computers and efficient, signal processing algorithms. The introduction of the first CT scanner in 1972 revolutionized medical imaging and has improved contemporary health care. There are many types of interaction phenomenon that can image the human body, thus giving the physician an array of diagnostic tools. However, the field of image reconstruction from projections is not limited to medical imaging. The diverse fields of radio astronomy, electron microscopy, geophysics and nondestructive testing all use the same CT concepts. The emerging localized tomography promises to provide solutions to problems containing only a partial set of projection data. Localized tomography will also help in cases where only a portion of the object is of interest
