Niels Alexander Lassen (December 7, 1926 – April 30, 1997) was a Danish nuclear medicine physician, neurologist and pioneer in the fields of neuroimaging, neuropsychiatry and nuclear medicine. He was born and died in Copenhagen.
Lassen has been called the greatest Danish brain researcher since Niels Steensen.[1]
Career
editHis father, H. C. A. Lassen, was professor at the University of Copenhagen, and Niels Lassen graduated as medical doctor from the same university in 1951. With his colleague Ole Munck he began in the 1950s to use radioactive isotopes for the measurement of the blood circulation in the brain, and in the beginning of the 1960s he together with David H. Ingvar from University of Lund began the development of methods for regional measurements on the brain with krypton-85 and xenon-133 isotopes.[2][3] These efforts were summarized in a Scientific American article in 1978.[4]
He was employed at Bispebjerg Hospital in 1958 to 1996. From 1963 he established and lead the department of Clinical Physiology. He wrote 710 scientific publications in the periode 1954-2000+. He was married to Edda Sveinsdottir who as a computer scientist helped with the development of the (at that time) advanced computer technology for image construction of the regional brain measurements.
The Niels Lassen Award
editThere is a Niels Lassen Award[5] presented by the International Society for Cerebral Blood Flow and Metabolism (ISCBFM). ((The Danish medical doctor, brain researcher and "science entertainer" Peter Lund Madsen was a student of Niels A. Lassen, and Peter Lund Madsen received the Niels A. Lassen Prize in 2002.[6]))
