BUSHBERG ESSENTIAL PHYSICS OF MEDICAL IMAGING PDF

The frst edition of this text was written in , and the second edition followed in Recognizing this, we have substantially reduced the treatment of analog modalities in this edition, including only a short discussion on screen-flm radiography and mammography, for example. Because the picture archiving and communication system PACS is now a concrete reality for virtually all radiological image interpretation, and because of the increasing integration between the radiology information systems RISs , the PACS, and the electronic medical record EMR , the informatics section has been expanded considerably. There is more to know now than 10 years ago, so we reduced some of the detail that existed in previous editions that may be considered nonessential today. Detailed discussions of x-ray tube heating and cooling charts, three-phase x-ray generator circuits, and CT generations have been shortened or eliminated.

The frst edition of this text was written in , and the second edition followed in Recognizing this, we have substantially reduced the treatment of analog modalities in this edition, including only a short discussion on screen-flm radiography and mammography, for example.

Because the picture archiving and communication system PACS is now a concrete reality for virtually all radiological image interpretation, and because of the increasing integration between the radiology information systems RISs , the PACS, and the electronic medical record EMR , the informatics section has been expanded considerably.

There is more to know now than 10 years ago, so we reduced some of the detail that existed in previous editions that may be considered nonessential today. Detailed discussions of x-ray tube heating and cooling charts, three-phase x-ray generator circuits, and CT generations have been shortened or eliminated.

The cumulative radiation dose to the population of the United States from medical imaging has increased about sixfold since , and the use of unacceptably large radiation doses for imaging patients, including children, has been reported.

In recent years, radiation dose from medical imaging and radiation therapy has become the focus of much media attention, with a number of radiologists, radiobiologists, and medical physicists testifying before the FDA and the U. Congress regarding the use of radiation in imaging and radiation therapy. The media attention has given rise to heightened interest of patients and regulatory agencies in the topics of reporting and optimizing radiation dose as well as limiting its potentially harmful biological effects.

In this edition, we have added an additional chapter devoted to the topic of x-ray dose and substantially expanded the chapters on radiation biology and radiation protection. The current International Commission on Radiological Protection system of estimating the potential detriment harm to an irradiated population; the calculation of effective dose and its appropriate use; as well as the most recent National Academy of Sciences Biological Effects of Ionizing Radiation BEIR VII report recommended approach of computing radiation risk to a specifc individual are discussed in several chapters.

Our publisher has indicated that the second edition was used by increasing numbers of graduate students in medical imaging programs. While the target audience of this text is still radiologists-in-training, we have added appendices and other sections with more mathematical rigor than in past editions to increase relevance to scientistsin-training. The goal of providing physicians a text that describes image science and the radiological modalities in plain English remains, but this third edition contains an appendix on Fourier transforms and convolution, and Chapter 4 covers basic image science with some optional mathematics for graduate student readers and for radiologists with calculus-based undergraduate degrees.

Some new technologies offer the possibility of substantially reducing the radiation dose per imaging procedure. All of the authors of this book are involved in some way or another with national or international advisory organizations, and we have added some perspectives from published documents from the American Association of Physicists in Medicine, the National Council on Radiation Protection and Measurements, the International Commission on Radiation Units and Measurement, and others.

Lastly, with the third edition we transition to color fgures, tables, text headings, and photographs. Most of the fgures are newly designed; some are colorized versions of fgures from previous editions of the text.

This edition has been completely rewritten and a small percentage of the text remains as it was in previous editions. We hope that our efforts on this third edition bring this text to a completely up-to-date status and that we have captured the most important developments in the feld of radiology so that the text remains current for several years to come.
