    Abstract: Apparatus, including: a mockup probe, having a distal end and a proximal end adapted to be held by a human operator. The apparatus further includes a mockup patient, simulating an actual patient, the mockup patient having an aperture allowing penetration of the distal end of the mockup probe into the mockup patient. The apparatus includes a force generator, coupled to the mockup probe so as to apply a force to the proximal end that can be felt by the human operator, and a system controller. The controller is configured to: track a location of the distal end during the penetration thereof into the mockup patient, access an indication of a value of contractility of a region of an organ of the actual patient corresponding to the location, and activate the force generator so that the force applied to the proximal end corresponds to the indication.

    Abstract: A position sensing system includes a probe adapted to be introduced into a body cavity of a subject. The probe includes a magnetic field transducer and at least one probe electrodes. A control unit is configured to measure position coordinates of the probe using the magnetic field transducer. The control unit also measures an impedance between the at least one probe electrodes and one or more points on a body surface of the subject. Using the measured position coordinates, the control unit calibrates the measured impedance.

    Abstract: A reliable endocardial map is obtained by constructing a matrix relationship between a small number of endocardial points and a large number of external receiving points using a multi-electrode chest panel. Inversion of the matrix yields information allowing the endocardial map to be constructed. Subsequent maps are obtained noninvasively using the multi-electrode chest panel, applying new electrical signals to the matrix relationship, and again inverting the matrix to generate new endocardial electrical maps.
