About the Author

Dr. Timothy G. Feeman, veteran mathematics professor at Villanova University, has been published in all of the leading mathematics journals and has received an award for expository writing from the Mathematical Association of America. In 2002, the American Mathematical Society published his first book, "Portraits of the Earth: A Mathematician Looks at Maps."

Reviews

From the reviews: "This new book by Timothy Feeman, truly intended to be a beginner's guide, makes the subject accessible to undergraduates with a working knowledge of multivariable calculus and some experience with vectors and matrix methods. ... The current book begins with a description of the imaging problem in the simplest possible situation, where the physics and geometry are clearest. ... author handles the material with clarity and grace. ... Doing that in a system like MATLAB or Maple would make for a very nice independent project." (William J. Satzer, The Mathematical Association of America, February, 2010) "This concise and nicely written book grew out of a course offered by the author in 2008 to undergraduate mathematics majors and minors at Villanova University. ... The book is well structured; the exposition is neat and transparent. All theoretical material is illustrated with carefully selected examples which are easy to follow. ... I highly recommend this interesting, accessible to wide audience and well-written book dealing with mathematical techniques that support recent ground-breaking discoveries in biomedical technology both to students ... and to specialists."
