PROBLEM TO BE SOLVED: To identify the area of a treatment target in a necessary and sufficient range for an abnormal area when an image diagnosis is conducted using a three-dimensional medical image representing an inner structure of a subject constituted by a branch structure and a peripheral structure.SOLUTION: A lesion area detection unit 33 detects an abnormal peripheral structure (lesion area) from the three-dimensional medical image, a pulmonary blood vessel extraction unit 32 extracts a branch structure (pulmonary blood vessel) from the three-dimensional medical image, an associated blood vessel identification unit 35 identifies an associated branch structure functionally associated with the abnormal peripheral structure based on position information of each point in the extracted branch structure, and an associated lung parenchymal area identification unit 36 identifies an associated peripheral structure (lung parenchyma) functionally associated with the identified associated branch structure based on the position information of each point in the extracted branch structure. |
