Opis

The new edition of this established text has been thoroughly revised and updated. It is divided into six parts. The first two parts cover the X-ray tube and X-ray generators. Part three looks at general, multipurpose radiographic equipment. Part four considers fluroscopic equipment, and the remaining two parts provide accounts of more specialized radiographic equipment and computer-based imaging modalities.
