Computed tomography is rather advanced and experienced an immense innovation boost in the past decade. Nowadays the reconstruction algorithms for rigid objects exhibit excellent image quality. Contrast and spatial resolution are sufficient for many diagnostic and interventional procedures.
The major problem that is still considered to be unsolved in CT is the reconstruction of non-rigid objects in the presence of a sparse set of projections and unknown motion parameters.
Periodic and non-periodic deformations can be due to patient motion, respiratory motion or cardiac motion.
In this talk I will present several novel approaches to cardiac reconstruction algorithms. I will start with the description
of an acquisition protocol for motion compensated reconstruction. We will show that image based gating for cardiac reconstruction
is superior to standard ECG gating in the presence of irregular cardiac motion. The core of the talk will focus on the design of
objective functions for motion compensated reconstruction and their efficient optimization.
All introduced methods are tested on real clinical data, and an overview of initial experimental results
will be presented.
