Medical images provide detailed information which doctors can use to diagnose heart disease and plan treatements. Conditions such as myocardial infarctions and dyssynchrony can be recognized by their distinct motion patterns in images. The progression of these diseases however, is influenced by elastic forces and the ability of the muscles to contract. These cannot be viewed in images by themselves, but can instead be determined with the help of a mathematical model which is personalized to a patient.

In his thesis Balaban has developed methods for the creation of personalized models of heart motion using data from medical images. The result is a computer model of a patient's heart which moves the same way as in the images. The personalized model can then be used to provide elastic force and contraction information. Such models have been contructed before, but with the methods developed in this thesis, much greater resolution and accuracy is possible.

Balaban's supervisors have been Senior Research Scientist Marie E. Rognes, Simula Research Laboratory and Senior Lecturer Joakim Sundnes, Department of Informatics, University of Oslo.
