Abstract
Positron emission tomography (PET) scans of brains result in
large datasets that are traditionally analyzed using visual
displays and statistical analyses. Due the complexity and multidimensionality
of the data, there exist many challenges in the
interpretation of the scans. This paper describes the use of a
sonification method to assist in improving the diagnosis of
patients with different levels of Alzheimer’s dementia. A tripletone
method is introduced, and the audible beating patterns
resulting from the interaction of the three tones is explored as a
metric to interpret the data. The sonification method is
presented and evaluated using subjective listening tests. Results
show the triple-tone sonification method is effective at
evaluting PET scan brain data, even for listeners with no
medical background.
