Method and device for simplifying information obtained from electrical impedance tomography

摘要

A method and apparatus to simplify information obtained through electrical impedance tomography, the method comprising the steps of data collection through electrical impedance tomography and the respective processing thereof; the application of at least one algorithm to detect conditions, trends and specific events, so as to allow the identification of at least one region of interest as well as the production of an image including at least such region, which can be pre-defined or defined by the user. The graphical representation of the region of interest can be obtained through the use of a color, texture, figure, contour, etc. The data processed can consist of the impedance values or data derived thereof.

1. A method to generate and display a simplified representation of information obtained through electrical impedance tomography, the method comprising:
collecting electrical impedance tomography (EIT) data through operation of an electrical impedance tomography apparatus on a body; processing the EIT data to detect one or more of a major condition, trend, or event therefrom; defining at least one region of interest of a lung from the EIT data, the at least one region of interest comprising a set of two or more pixels determined to have in common the major condition, trend, or event detected from analyzing the EIT data, wherein at least some pixels of the set have different impedance values; and generating and displaying a graphical representation of the lung of the EIT data on an electronic display, the graphical representation of the lung displayed with a common visual feature over the at least one region of interest that overrides display of impedance information of each individual pixel within the at least one region of interest.
