Abstract: A radiographic image analysis apparatus includes a hardware processor that calculates an area of a lung field from a chest image obtained by radiation imaging of a chest in one direction, and estimates a residual volume, a functional residual capacity, a total lung capacity or a residual volume ratio of the lung field, based on the calculated lung field area.
