Recommended further reading:
Geoff Dougerty: "Digital Image Processing for Medical Applications",
Cambridge 2009, ISBN 978-0-521-86085-7
Excellent book that combines both the physics of imaging modalities
and the computer processing steps needed for image formation
and for further image processing.
This book is a great complement for the class notes and strongly recommended.
Essential Physics of Medical Imaging
by G. Bushberg et al.
Lippincott Williams & Wilkins
This textbook covers all aspects of medical image acquisition. Presents an
understanding of the theory and applications of the science including basic
concepts, X-ray imaging, ultrasound, MRI, nuclear medicine, radiation
protection, radiation dosimetry, and radiation biology. Abundant illustrations.
This book is directed at students with a medical background.
The Image Processing Handbook
by John C. Russ
CRC Press
A very comprehensive and extensive book covering all aspects of image
processing in Engineering and Science. Unfortunately, this comes at
a relatively high price.
Digital Image Processing Algorithms and Applications
by Ioannis Pitas
Wiley-Interscience
This book is a good reference for those of you who are
interested in actually programming those algorithms. It provides
lots of C source code. However, algorithms are limited to entry-level image processing
methods.
Magnetic Resonance Imaging: Physical Principles and Sequence Design
by E. Mark Haacke, Robert W. Brown, Michael R. Thompson, Ramesh Venkatesan
John Wiley & Sons
For those of you who really want to get into MRI, this book provides
even more in-depth MRI knowledge, covering the special area of sequence design
for specific medical and research applications

The grade will be based about equally on the homeworks, the midterm exam, and the final exam. You will receive score points based on the fill-the-bucket principle, i.e. for each homework assignment and for each test, you accrue score points. Your final grade will be determined from the score you achieved relative to the maximum score achievable. Typically, you receive a maximum of 20 points per homework, and 100 points per test, resulting in a maximum score of around 300 points.
We use a fixed grading system. There will be no adjustment based on the overall class performance. To earn a passing grade, you will have to achieve an overall score of at least 45%. The following table shows the percentage of your score you need to reach for a specific grade:
Grade | Minimum percentage | Grade | Minimum percentage | Grade | Minimum percentage |
A | 95% | A- | 90% | ||
B+ | 85% | B | 80% | B- | 75% |
C+ | 70% | C | 65% | C- | 60% |
D+ | 50% | D | 45% |
If you reach a cumulative score of 90% or more through homeworks and Midterm by the last day of classes, you may opt out of the Final. Your grade will then be based on your cumulative score in percent of the achievable score up to that point. To opt out of the Final, you need to let me know before the last day of class.
