5Preface
Radiographic technologists and darkroom laboratory technicians are responsible for the important task of exposing the patient in the X-ray machine for tests and processing the exposed film, resulting in a perfect radiograph. The usefulness of the radiograph depends on its quality; result of technique used and processing.
This book is intended to provide a reliable guidance to these technicians and also to those who want to take up this field as a profession.
These technologists are aware that a wrongly handled X-ray test will necessitate a repetition, resulting in additional cost, difficulties in getting the patient again and sometimes serious problems in urgent cases. This also involves additional radiation to the patient. It is well known that the use of X-rays for diagnostic purpose needs to be kept at the minimum. Thus, the technologists have a great responsibility in taking a radiographic test.
Manufactures of equipments, films, processing chemicals and other gadgets have been continuously improving the quality and reliability of their products by research and development and also introducing automation so that human error is minimized and good quality radiographs are possible. It is believed that this book will help in making this possibility into everyday reality.
Since the work of the radiographer and processing assistant are complementary to each other, both subjects are included in this volume.
This book is, as already stated above, is a guide and useful to those who already have undergone a basic training and also as a textbook for the new entrants.
