Chesneys Equipment for Student Radiographers

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.
