Bjorn A. J. Angelsen, dr.techn., was born in Vestvågøy, Norway, in 1946. He is Professor of Biomedical Engineering at the Norwegian University of Science and Technology, NTNU, since 1983. He received a degree in electrical engineering (equivalent of MEE) from the same university in 1971, and a dr.techn. degree in electrical engineering (Ph.D) in 1977.

From 1975 to 1982 he was with the Division of Automatic Control, SINTEF (The Foundation of Scientific and Industrial Research at the Norwegian Institute of Technology), Trondheim, Norway. From 1977 to 1979 he was on leave at the Department of Electrical Engineering, University of California, Berkeley, and the Division of Biomedical Engineering, Stanford Research Intstitute, Menlo Park, CA. Since 1980 he was an adjunct professor of Biocybernetics at the Division of Engineering Cybernetics, NTH, and since 1983 a Professor of Biomedical Engineering at the Medical Faculty of NTNU, Trondheim.

He has spent most of his professional life in the field of medical ultrasound imaging, pioneering cardiac applications of ultrasound Doppler measurements in the 1970's. For this work he co-authored with Professor Liv Hatle, MD, the book "Doppler Ultrasound in Cardiology - Physical Principles and Clinical Applications" (1st edition in 1982), which also has been translated to French and Japanese. The work spured product development in the medical ultrasound company Vingmed Sound AS®, which has changed its name to GE Vingmed Ultrasound after being acquired by GE Medical Systems® in 1997. His research interests include nonivasive diagnosis with emphasis on ultrasonic diagnosis and the use of biomathematical models to extract physiologic information from the measurements. He has authored and co-authered more than 60 papers on engineering and medical problems related to ultrasound diagnosis of the vascular system.

In the 1980s he was heavily involved in development of annular array color flow imaging technology with Vingmed Sound® and intravascular ultrasound imaging with CVIS. The work was taken into cardiac physiology and noninvasive measurement of myocardial performance. Since the mid 1990's he has been working on ultrasound wave propagation in heterogeneous tissue, especially with aspects of corrections of phase aberrations and pulse reverberations. Part of this work is reported in the book together with new work on non-linear wave propagation in heterogeneous tissue and non-linear scattering from ultrasound contrast agents.

In 2007, he was bestowed the Ian Donald Medal for Technical Merit.
