An imaging procedure that involves the use of computer-processed combinations of many X-ray measurements is known as computed tomography or X-Ray CT. These X-ray measurements are taken from different angles in order to create cross-sectional images. The measurement focuses on specific areas of the scanned object. This technique is beneficial as it helps users to see inside the object without cutting. The most common application of X-ray computed tomography is medical imaging. Cross section images of this procedure are utilized for diagnostic and therapeutic purposes in various medical disciplines. Apart from X-ray CT, there are some other types of computed tomography such as positron emission tomography and single photon emission computed tomography. CT is also used in various other fields, such as nondestructive materials testing. It also has archaeological uses such as imaging the contents of sarcophagi and ceramics. This book contains some path-breaking studies in the field of computed tomography. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. The book is appropriate for students seeking detailed information in this area as well as for experts.
