To enable easily diagnosing or examining the pancreas even when the main pancreatic duct is visualized partially interrupted on an image.SOLUTION: A medical image processing apparatus according to an embodiment includes an obtaining unit, a first extracting unit, a second extracting unit, an identifying unit, and an estimating unit. The obtaining unit is configured to obtain a medical image related to a pancreas. The first extracting unit is configured to extract a pancreas region included in the medical image. The second extracting unit is configured to extract at least one tubular structure region from the inside of the pancreas region. The identifying unit is configured to identify a first end part and a second end part related to the pancreas on the basis of the pancreas region. The estimating unit is configured to estimate a primary pancreatic duct centerline of the pancreas on the basis of the tubular structure region, the first end part, and the second end part.SELECTED DRAWING: Figure 1 【課題】画像上で主膵管の一部が途絶して描出される場合でも、膵臓の診断や検査を容易に行うことができるようにすること。【解決手段】実施形態に係る医用画像処理装置は、取得部と、第１の抽出部と、第２の抽出部と、特定部と、推定部とを備える。取得部は、膵臓に関する医用画像を取得する。第一の抽出部は、前記医用画像に含まれる膵臓領域を抽出する。第２の抽出部は、前記膵臓領域内から少なくとも一つの管状構造領域を抽出する。特定部は、前記膵臓領域に基づいて、前記膵臓に関する第１の端部及び第２の端部を特定する。推定部は、前記管状構造領域、前記第１の端部及び前記第２の端部に基づいて、前記膵臓における主膵管芯線を推定する。【選択図】図１
