Fusion of images obtained from EIT and MRI

A novel and effective methodology of combining images obtained by both electrical impedance tomography (EIT) and magnetic resonance imaging (MRI) data is described. Co-registered and fused image results for an example laboratory phantom based on the polysaccharide gel TX151 are presented. Bespoke software was used to convert an EIT dataset into a form consistent with 3D-Slicer, a powerful software package used for visualisation and image analysis. The data fusion provides a highly effective method of directly comparing EIT images, which typically have good temporal resolution and relatively poor spatial resolution, with those obtained with MRI, which has relatively poor temporal resolution but excellent spatial resolution.
