 where his ability to apply techniques from one field to another did not go unnoticed. He was universally characterized as "likable", "friendly", "amusing", "creative", "intense", and "humble".

Oldendorf's interest neuroimaging was precipitated by a dislike for invasive procedures (like pneumoencephalography

At UCLA, he started his seminal investigations into the two major lines of research that would define his career: X-ray shadow radiography

Role in development of neuroimaging

In 1959, Oldendorf conceived an idea for "scanning a head through a transmitted beam of X-rays, and being able to reconstruct the radiodensity patterns of a plane through the head" by watching an engineer who was working on an automated apparatus to reject frost-bitten fruit by detecting dehydrated portions. Not until 1961 did he complete a working prototype of his idea, apply (for $1700) for a patent on his idea, and publish an article detailing the work. Ingeniously, by using materials found in his home (such as his son's toy train, a phonograph turntable, and an alarm clock motor), Oldendorf demonstrated a method of producing cross-sectional images of soft tissue by back-projection and reconstruction

. In his landmark paper, also published in 1961, he described the basic concept later used by Allan McLeod Cormack

 of blood-brain permeability. The idea of the blood-brain barrier was already entrenched in medical science by this time, but had never been quantified.

His methods of assessing blood-brain barrier permeability increased knowledge of the mechanisms whereby drugs

Today, most of what is known of the selective permeability of the blood-brain barrier was either established by Oldendorf in his laboratory, or by others using his ingenious techniques. These results have been essential in developing PET and SPECT imaging; in studying glucose

Professional publications and societies

In his lifetime, Oldendorf wrote three textbooks and over 250 scientific articles, including The Quest for an Image of the Brain: Computerized Tomography in the Perspective of Past and Future Imaging Methods (Raven Press, New York, 1980) and Basics of Magnetic Resonance Imaging (Kluwer Academic Press, Boston, 1988).

. He participated in the ad-hoc committee that unanimously voted to form the Society for Computerized Tomography so as to continue its educational activities. Realizing that other imaging modalities may eventually be prominent, the following year Oldendorf pushed to have the name of the society changed to Society for Computerized Tomography and Neuroimaging, and served as its president from 1978 to 1979. This society was to rename itself the American Society for Neuroimaging (ASN) in 1981, also with the prodding of Oldendorf.

 degrees). Rosalyn Yalow, a Nobel laureate herself, nominated Oldendorf for the prize and was reportedly upset that he did not get it. In the January 1980 issue of the journal Science (vol. 207, page 31), William J. Broad wrote an article titled "The Riddle of the Nobel Debate" in which he posited that politics in Stockholm forced the removal of Dr. Oldendorf's name during the nomination process. It was theorized that giving the prize to another American could sway pending patent litigation in Europe over the rights to the CT Scanner.
