3-D imaging of coronary vasculature using C-arm CTCoronary heart disease is the most common cause of death in
the developed world.
Its main cause is obstruction of the coronary arteries.
Today, the evaluation of
these stenoses in the interventional lab is performed using
C-arm fluoroscopy.A full 3-D visualisation can improve the clinical
assessment. Unfortunately, 3-D
reconstruction of the coronary tree from C-arm data is a
mathematically
ill-posed problem. Due to the long acquisition time of ca. 5
seconds, heart
motion blurs the resulting image. There is previous work on
the estimation of
and compensation for coronary vessel movement, achieving a
good visualisation of
the coronary morphology. However, heart motion estimation is
only approximate,
resulting in e.g. uncertainties in the quantitative
determination of vessel
diameters. The research goal in this project is the optimisation of the
3-D reconstruction
of coronary vasculature towards a quantitative
representation. The following
aspects are considered:
generation
motion estimation
