[0017] overview

[0018] Medical procedures, such as electrophysiology (EP), may involve placing one or more body surface electrodes (BSE) on the patient's body. Exemplary BSEs include electrocardiogram (ECG) electrodes and advanced current localization (ACL) electrodes for positioning internal devices such as catheters. Each BSE is typically coupled to a patch that a medical operator can place on the patient's torso.

[0019] In an ACL-based EP procedure, for example, a physician catheterizes a patient's heart and uses multiple ACL electrodes for measuring the body impedance between each of the ACL electrodes and the distal end of the catheter. Integration of impedance measurements allows tracking of the position of the distal tip.

[0020] Proper placement of the patch on the patient's torso (eg, relative to the patient's heart) is important to the accuracy and reliability of the procedure. Occasionally, at least one of the meshes is incorrectly placed, in which case the ...

Abstract

A method for electrode placement includes acquiring an image of a body of a patient, such that the image captures a patch that has been placed on the body. Based on the acquired image and the patch appearing therein, one or more preferred locations are calculated on the body for placing one or more respective electrodes to be used in carrying out a procedure in an internal organ of the patient. The preferred locations are displayed to an operator.

Description

technical field [0001] The present invention relates generally to body surface electrodes, and in particular to methods and systems for determining locations on a patient's body for placement of body surface electrodes. Background technique [0002] Body surface electrodes (BSE) are used in some medical procedures, such as electrophysiology (EP). Examples of prior art techniques for using and determining the location of a BSE are provided below. [0003] PCT International Publication WO 2008 / 032291, the disclosure of which is incorporated herein by reference, describes an adhesive electrode patch assembly, particularly for impedance measurements, having at least one electrode patch assembly. At least one electrode patch includes at least one feeding electrode and at least one sensing electrode respectively arranged in pairs, wherein one feeding electrode and one sensing electrode are combined into a single electrode plate. [0004] U.S. Patent Application Publication 2011 / ...
