Abstract

Un método incluye recibir, desde una sonda que comprende electrodos y se ubica dentro de una cavidad en un órgano de un paciente, (i) señales de proximidad indicativas de la proximidad de los electrodos a una pared de la cavidad, y (ii) señales de posición indicativas de las posiciones de los electrodos dentro de la cavidad; basada en las señales de proximidad y las señales de posición, al menos una porción de un volumen de la cavidad está representada por un modelo de esfera que incluye múltiples esferas; se identifica una dirección a lo largo de la cual una o más esferas son más grandes que una o más esferas circundantes por al menos un factor dado; basada en la dirección indicada, se estima y presenta a un usuario una ubicación de una abertura en la pared de la cavidad.
