Computed Tomography: Principles, Techniques and Clinical Applications

Computed tomography is an imaging procedure that makes use of computer-processed combinations of many X-ray measurements. The X-ray measurements are taken from different angles to produce cross-sectional images of particular areas of a scanned object. This helps in seeing inside the object without cutting. Computed tomography is an important tool in medical imaging which supplements medical ultrasonography and X-rays. It is primarily used for preventive medicine or screening for disease, such as CT scanning of head, lungs, angiography, etc. CT scanning of the head is used to detect medical conditions such as bone trauma, tumors, infarction and calcifications. CT scanning of lungs is used for detecting both acute and chronic changes in the lungs parenchyma. In angiography, it is used to visualize arterial and venous vessels throughout the body. In cardiac imaging, it is performed to gain knowledge about cardiac and coronary anatomy. This book unravels the recent studies in the field of computed tomography. The topics covered herein deal with the core aspects of this field. This book will prove to be immensely beneficial to students and researchers in medical imaging.
