This concise and completely up-to-date study guide bridges the gap between a physics textbook and a self-test format exam aid. It comprehensively covers all the areas examined in the FRCR part 1, and by focusing on understanding the key concepts, rather than simply being able to answer questions correctly, this guide adopts a comprehensive, wide-ranging approach. It includes the latest updated radiation safety legislation (IR(ME)(A)R), and all information has been checked by a medical physicist as well as radiologists. The unique format features self-test MCQs with correct answers and associated key concepts. Test yourself over an entire topic, then check your answers at the back of the book. If you were not successful, you will not only be able to find the correct answers, you will understand where you have gone wrong. This book is highly recommended for candidates for the Fellowship of the Royal College of Radiologists (FRCR) part 1 examination.
