The website is written by Allen D. Elster. In 1994 y Allen published the first edition of Questions and Answers in Magnetic Resonance Imaging, a collection of notes on MR physics he had distributed to residents and fellows during viewbox teaching over the years. Jonathan Burdette helped him update this material and the second edition appeared in 2001. These books were big hits in the radiology community, and he still take pride how many people tell me they learned most of what they know about MR physics from them. There is no charge for using this site; it is his gift back to the MRI community.

This course presents the fundamentals of digital signal processing with particular emphasis on problems in biomedical research and clinical medicine. It covers principles and algorithms for processing both deterministic and random signals. Topics include data acquisition, imaging, filtering, coding, feature extraction, and modeling. The focus of the course is a series of labs that provide practical experience in processing physiological data, with examples from cardiology, speech processing, and medical imaging. The labs are done in MATLAB® during weekly lab sessions that take place in an electronic classroom. Lectures cover signal processing topics relevant to the lab exercises, as well as background on the biological signals processed in the labs.
