A Course In Physics For Medical And Dental Students Etc PDF Download

This book is intended as a textbook for a course in medical physics in the university for the first year students of the medical ,dental ,pharmacology , and assistances colleges as graduate programs. The book may also be of interest to the large number of professionals, not only physicists, who in their daily occupations deal with various aspects of medical physics and have a need to improve their understanding of physics in medicine . Medical physics is a branch of physics concerned with the application of physics to medicine.It is concerned with the application of physics to medicine mainly, but not exclusively, in the application of light, laser , sound , electricity, ionizing radiation temperature, forces, and nanophysics to diagnosis and treatment of human disease.The main target audience for this book is graduate students in medical physics and these students are assumed to possess the necessary background in physics and mathematics to be able to follow and master the complete textbook. Medical residents, technology students and biomedical engineering students, on the other hand, may find certain sections too challenging or esoteric; however, there are many sections in the book that they may find useful and interesting in their studies.It contains thirteen chapters, each chapter covering a specific group of subjects related to radiation physics that, in my opinion, formthe basic knowledge required from professionals working in contemporary medical physics. Most of the subjects covered in this textbook can be found discussed in greater detail in many other specialized physics texts, such as quantum mechanics, modern physics, etc.; however, these texts are aimed at students in a specific physics specialty. They provide more in-depth knowledge of the particular specialty but provide no evident link with medical physics.To recognize the importance of terminology , Appendix 1, provides terminology in medicine and dents. In diagnostic procedures relatively low energy x rays (diagnostic radiology) and gammarays (nuclear medicine) are used; in therapeutic procedures most commonly high energy (megavoltage) x rays and gamma rays or megavoltage electrons are used (radiation therapyor radiation oncology or therapeutic radiology). Other applications of physics to medicine include the use of nuclear mag-netic resonance in diagnosis of disease (magnetic resonance imaging), ultra-sound in imaging, bioelectrical investigations of the brain (electroencephalog-raphy) and heart (electrocardiography), biomagnetic investigations of the brain (magnetoencephalography), medical uses of infrared radiation (thermog-raphy), heat for cancer therapy (hyperthermia), and lasers for surgery (laser surgery).The four important sub-specialties in medical physics are related to:1. Diagnostic imaging with x rays (diagnostic radiology physics).2. Diagnostic imaging with radio-nuclides (nuclear medicine physics).3. Treatment of cancer with ionizing radiation (radiation oncology physics).4. Study of radiation hazards and radiation protection (health physics).
