With every chapter revised & updated Physics for Diagnostic Radiology Third Edition continues to emphasise the importance of physics education as a critical component of radiology training. This bestselling text helps readers understand how various imaging techniques work from planar analogue & digital radiology to computed tomography (CT) nuclear medicine & positron emission tomography (PET) to ultrasound imaging & magnetic resonance imaging (MRI). New to the Third Edition Material on digital receptors Emphasis on the differences between analogue & digital images Coverage of multi-slice CT & three-dimensional resolution dual energy applications & cone beam CT Special radiographic techniques including subtraction techniques & interventional radiology New chapter on PET with discussion of multi-modality imaging (PET/CT) Additional material on radiation doses & risks to patients New chapter covering picture archiving & communication system (PACS) teleradiology networks archiving & related factors A summary of the main teaching points at the beginning of each chapter After an introductory chapter on basic physics the book follows the x-ray imaging process: production of x-rays interaction with the patient radiation measurement the image receptor the radiological image & image quality assessment. It then covers more advanced x-ray techniques as well as imaging with radioactive materials. The text also focuses on radiobiology risk & radiation protection & imaging with non-ionising radiation. The final chapter discusses data handling in a modern electronic radiology department.
