According to one implementation, the system includes, a capturing unit, a deforming unit, and a generating unit. The capturing unit captures a dynamic state of a thoracic portion to generate a plurality of frame images. The deforming unit sets a reference point in a position corresponding to each other among the plurality of generated frame images. The deforming unit extracts a lung field region from each of the frame images. The deforming unit deforms a shape of the lung field region so that a distance from the set reference point to an outline of an outer side of the lung field region becomes a certain distance. The generating unit analyzes a dynamic state in the lung field region and generates an analysis result image showing a result of the analysis in a corresponding position in the deformed lung field region.
