This study guide is for students majoring in the natural sciences or technical fields who have a solid basic education in physics. It covers in turn the physics of the body, and the physics of diagnostic and therapeutic methods. The topics include breathing and metabolism, fluid dynamics of the circulatory system, heat, X-ray diagnostics and computer tomography, ultrasound, nuclear diagnostics and positron emission tomography, radiation medicine and protection, and laser therapy.
