Medical Imaging is the technique and process used to create images of the human body for medical procedures seeking to reveal, diagnose, or examine disease to provide treatment. In this book attempts have been made to present the study format for ancient and modern medical imaging practices. The book is divided in three units. Each unit contains full explanation of theories and solution of research related problems. The first unit introduces about the Radiology basic theme and its specification and general criteria. Second unit deals with the general practical approach with X-ray diagnostic. Third unit deals with the modern technicality and important aspects of imaging in CT and MRI. Any suggestion and constructive criticism in the development of this book will be appreciated.
