Abstract:
We present a novel method for representing
the electrical depolarisation and
repolarisation of cardiac cells using real-time
volumetric animation techniques. The visual
representation coincides with automatically
synchronized electrocardiogram (ECG) input.
Whilst other projects in similar fields use
super-computers or vastly complex cellular
structures, one of the aims of this project is to
simplify the process for real-time
optimization. The current techniques are
being used in a teaching tool and also are
being implemented in a myocardial infarction
diagnostic tool. Cellular automata are used to
demonstrate the electrical progression with a
multi-pass nearest-neighbour algorithm and
automatic ECG recognition and detection
algorithms are used to synchronize the
animation with the inputted ECG. We use
texture-based slices to represent the
myocardial volume to improve speed.
