Computed Tomography Fundamentals, System Technology, Image Quality, Applications.(Book review)

COMPUTED TOMOGRAPHY FUNDAMENTALS, SYSTEM TECHNOLOGY, IMAGE QUALITY, APPLICATIONS. 2nd ed. Kalendar W. 2006. 304 pgs. Wiley-VCH Verlag GmbH & Co, Weinheim, Germany. www.wiley.com. $75.00.

This textbook is a comprehensive reference book for computed tomography (CT) radiographers, radiologists and other individuals associated with CT technology. The author's introduction states that the second edition contains additional and updated information on the newest technology in CT.

The book begins with a historical overview of CT and basic concepts of CT imaging, followed by a discussion of new and modern CT technology. Multislice spiral CT and cone-beam spiral CT scanning, spatial and low contrast resolution and sampling in the Z-direction also are discussed in depth.

The textbook includes information on quality control in the newer technologies and reducing radiation dose. Two-dimensional and 3-D image displays are provided, along with recommendations on the choice of display. Mathematical aspects of CT image reconstruction are simply, yet thoroughly, explained so that individuals without a physics background can comprehend the material.

Cardiac and quantitative CT imaging and their uses are discussed. The charts, graphs and formulas are easy to read and follow. The glossary in the back of the book, with quick references for formulas and definitions, is an excellent reference guide.

I especially like the author's "5 wishes" segment, which discusses current needs in the CT technology field and shows the author's personal side. Personally, I believe that his fifth wish is extremely important: "Make known to the users and to the public that CT is a safe low-dose imaging modality." This is valuable information and health care workers in the CT field probably would agree.

The CD-ROM that accompanies the text adds additional insight into CT imaging by allowing the reader to review case histories and images. This information is a valuable tool. Any weaknesses in this textbook are too minor to mention. I feel this textbook is an excellent resource for individuals in the imaging field.
