Abstract

After the publication of our obituary of Liv Hatle1 a memorial event was held in her honour in Leuven, at which more details came to light about the development and initial clinical evaluation of the PEDOF machine (Pulsed Echo-Doppler Flowmeter), one of which was used by Professor Hatle in her studies. We would like to share these details as an addendum to our earlier report. After the University of Trondheim (UNiT) was founded in 1968, the head of the local health service, Sjur Børve, wanted to get a medical faculty established in co-operation with NTH (the Technical High School, which later became the Norwegian University of Science and Technology, NTNU). He offered Alf Brubakk, who had organized a medical students’ conference in Trondheim, a research position financed by the county, and Brubakk through a friend heard of Rune Aaslid, a student at NTH who claimed that he could make a mathematical model of the cardiovascular system. From 1970, ‘the ambitious idea was to perform measurements on the model that we could not perform in a patient then use the model to obtain the data that we could not measure in the patient’.2 Supported by Professor Jens Glad Balchen at the Department of Cybernetics, Rune Aaslid made an analogue computer (called ‘Jenny’) (Figure 1) that modelled pressure and flow at multiple sites in the vascular tree.3
