CONSTRUCTION OF BODY SURFACES FROM LOCALISED ELECTRODE POSITIONS TAKEN BY STEREO IMAGES

Detailed information about the electrophysical behaviour of the heart can be obtained by measuring electrical potentials in combination with the position of the measurement electrodes and the conductivity distribution in the body. This study describes a less expensive approach to create a model of a human thorax, and thus, the conductivity distribution. In a preprocessing step, a rigid electrode set is matched onto a standard volume dataset. The radial basis functions are introduced to deform this dataset. Different radial basis functions are analysed and the results presented.
