Principles of Computerized Tomography (CT)

Fundamentally, tomographic imaging deals with reconstructing an image from its projections. For some applications, the harm caused by the use of x-rays, an ionizing radiation, could outweigh any benefits that might be gained from the tomogram.The term “ computed tomography ,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images, or “slices. Tomography refers to the cross-sectional imaging of an object from either transmission or reflection data collected by illuminating the object from many different directions. Look for editions of this book at your library, or elsewhere.

Principles of Computerized Tomography Imaging

The errors discussed in the last chapter are fundamental to the projection process and depend upon the interaction of object inhomogeneities with the form of energy used.While the book focuses on computerized tomog-raphy with x-rays, variations of tomography are also discussed.

Principles of computerized tomographic imaging:

In the strict sense of the word, a projection at a given angle is the integral of the image in the direction specified by that angle, as illustrated in Fig.Tomography refers to the cross-sectional imaging of an object from either transmission or reflection data collected by illuminating the object from many different directions. In the case of straight ray propagation, the measurement can be of either the amplitude or the time of . This paper gives an overview of the mathematical .1 Introduction The tomographic images up to this point have generally been formed by illuminating an object with some form of energy (x-rays, microwaves, or ultrasound) and measuring the energy that passes through the object to the other side.In this chapter we will deal with the mathematical basis of tomography with nondiffracting sources.March 24, 2006.
