Abstract: A pulmonary function identifying and treating method includes: obtaining a first image, having first image elements, and a second image, having second image elements, respectively corresponding to a first state and a second state of a lung; extracting first feature points of the first image and second feature points of the second image; registering the first image with the second image using a boundary point set registration method and an inner tissue registration method according to the first feature points and the second feature points, so that the first image elements correspond to the second image elements and tissue units of the lung; determining functional index values representative of the tissue units of the lung using a ventilation function quantification method according to the first image elements and the second image elements corresponding to the first image elements; and treating the lung according to the functional index values.
