Abstract:
1. An image processing apparatus comprising: a contrast side obtaining unit configured to, on the basis of contrast data obtained after contrast radiography is performed, obtain a contrast area and a high computed tomography (CT) value area around the contrast area; an estimating unit configured to, on the basis of the contrast data and aligned non-contrast data obtained without contrast, estimate a contrast area in the non-contrast data and corresponding to the obtained contrast area; a simple side obtaining unit configured to obtain a high CT value area around the estimated contrast area on the basis of the non-contrast data; a core area computing unit configured to, on the basis of a distribution of CT values of the contrast data, compute a core area included in the high CT value area of the contrast data and to, on the basis of a distribution of CT values of the non-contrast data, compute a core area included in the high CT value area of the non-contrast data; a synthesizing unit configured to, on the basis of the core area of the contrast data and the core area of the non-contrast data, align the contrast data with the non-contrast data and generate superimposed data by superimposing the high CT value area of the contrast data on the non-contrast data; and a display control unit configured to display the superimposed data on a display device.
