radiation has been used in medicine since from the discovery of x-rays in 1895 by the german physicist wc roentgen. over the period, its application has grown enormously and it is used today in the form of radiography, fluoroscopy, mammography and computed tomography. nonradiation tools are also competing in medicine in the form of ultrasound and magnetic resonance imaging. these tools not only provide early differential diagnosis of the disease but also improve the accuracy of clinical diagnosis. the uniqueness of the above tools is that they all work on the basis of physics principle. understanding the physics of the above instruments is very much essential, for those connected with radiological sciences. it helps not only the education, but also the equipment selection, its optimal use, maintenance, and safety. hence, an attempt is made to explain the physical principle, instrumentation, function, its application and limitations in the form of a single book. attempt is also made to incorporate nuclear imaging and radiological safety in the same book. large numbers of figures and tables are incorporated wherever it is necessary, for better understanding of the concept. this book is intended for postgraduate students of medical physics, diagnostic radiology, diplomat national board (dnb), and frcr. this is the first book of its kind from an indian author, giving single solution for the entire range of radiology and imaging equipment. ‘the physics of radiology and imaging’ written by professor dr k thayalan, former professor and head of the department of radiology physics, barnard institute of radiology, is a quintessence of basic and applied physics thoroughly explaining principles of physics of computed and digital radiography, image intensifier fluoroscopy, mammography, ultrasound, computed tomography and magnetic resonance imaging. all the chapters are well laid out with good explanations and illustrations. fundamentals have been brought out in a unique way for easy assimilation into memory of teachers and students. explanations on image resolution, contrast, artifacts on different modalities are very vivid and nice for good understanding of the complex details.
