Reproduction and representation of an object's form in a visual representation is referred to as imaging. The application of methods and materials for generating, preserving and making duplicate images is known as imaging technologies. In medical intervention and clinical analysis, processes and techniques of imaging the internal body is known as medical imaging. It creates a database of physiology and normal anatomy, in order to detect abnormalities. It is a subset of biological imaging that includes radiology, which employs imaging technologies such as X-ray radiography, ultrasound, magnetic resonance imaging, endoscopy, tactile imaging, elastography, thermography and medical photography. It facilitates rapid diagnosis with quantitative assessment and visualization, which has made it a significant tool in clinical analysis. This book attempts to understand the multiple technologies that are used for medical imaging. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study.
