In this dataset we can find geometrical setups that served as an input to carry forward electrical impedance simulations with EIDORS. A 3D geometrical models of one ablation catheters combining measurements of local impedance (LI) and contact force (CF) commercially available is included. The objective of these in silico experiments laid on understanding how CF and tissue deformation affect LI measurements.To achieve it, using the catheter against the tissue, several grams of force are applying.The dataset consists of the original geometrical models before deformation and a couple of examples of the deformed one. Data structure geos: original geometries of the catheter and the tissue in stl catheter.stl tissue.stl geos_deformed: deformed geometries at 5 and 10 grams, respectively.
