Abstract

A three-dimensional ventilation image generation method, and a controller and an apparatus. The method comprises: generating a three-dimensional ventilation image by means of a signal extraction algorithm and an image reconstruction algorithm and according to an electrical impedance signal obtained by performing electrical impedance measurement on a target region to be measured, wherein performing electrical impedance measurement on said target region is implemented by using an electrode array that is three-dimensionally distributed on the periphery of said target region.
