Abstract: A gastro-electrical activity mapping system and method may comprise a catheter insertable through a natural orifice into the gastro-intestinal (GI) tract and comprising an array of electrodes for contacting an interior surface of a section of the GI tract to detect electrical potentials at multiple electrodes, and comprises a signal analysis and mapping system arranged to receive and process electrical signals from multiple electrodes of the array and spatially map GI smooth muscle electrical activity as an activation time map, a velocity map, or an amplitude map, which may be in the form of contour plots and may be mapped on an anatomical computer model of at least the section of the GI tract and may be animated.

Abstract: A biophysical virtual model of a body or body section of a human subject contains measured parameter values, scan data and images from surface or full body imaging systems, and also descriptive and subject identification data. Data in the model are applied to customize external objects ergonomically to fit a subject, by adjustment or by selection when the objects are configured for one or a group of subjects. The database can be centralized and/or mobile devices carried by users can supply model data to external apparatus. Where a parameter value needed for a subject is unknown, the statistical distribution of the database and the correlation of parameters can supply a probable value and level of certainty. In connection with values that are known for an individual, complexities inherent in the combination of plural parameters can be collected in the model and used in later security screens to confirm the identity of a subject.
