Medical imaging is the technique of producing images of the internal parts of the body. It facilitates medical intervention and clinical analysis, along with providing a visual representation of the functioning of tissues and organs. It reveals the internal structures that are covered by bones and skin, and helps in diagnosing and treating various diseases. Medical imaging makes use of various radiological and organic imaging techniques that utilize electromagnetic energies, sonography, isotope, magnetic, and thermal imaging. There are various types of medical imaging that are utilized currently for health care, including radiography, ultrasound, tomography, magnetic resonance imaging, photoacoustic imaging and echocardiography. Medical imaging is developing at a fast pace due to various developments in the techniques of image processing, including recognition, analysis and enhancement of images. Technological advancements that will contribute in presenting in depth visualization at the cell level are the future of medical imaging. This book contains some path-breaking studies on medical imaging. There has been rapid progress in this field and its applications are finding their way across multiple areas of medicine. This book will serve as a valuable source of reference for graduate and post graduate students.
