A medical image processing apparatus according to the embodiment includes a region-of-interest acquisition unit, a treatment plan acquisition unit, an influence degree calculation unit, and a display control unit. The region-of-interest acquiring unit acquires an image of partial region of a patient's body as a region-of-interest image. The treatment plan acquisition unit acquires a treatment plan information determined at a planning stage of a radiation therapy to be performed on the patient. The influence degree calculation unit calculates an influence degree indicating an influence exerted on a region of interest in a range until the radiation that radiated on the patient reaches target site in the patient body to be treated. The display control unit generates a display image on which the influence degree information is superimposed on the current fluoroscopic image of the patient and causes the display unit to display the generated display image.實施形態之醫用畫像處理裝置，係具備有關注區域取得部、和治療計畫取得部、和影響度計算部、以及顯示控制部。關注區域取得部，係將病患之體內之一部分的區域作為關注區域而取得。治療計畫取得部，係取得在對於前述病患所進行的放射線治療之計畫階段處所決定之治療計畫資訊。影響度計算部，係計算出影響度，該影響度，係代表照射至前述病患處的放射線之於直到到達前述病患之體內的進行治療之對象之部位處為止的飛行行程中之對於前述關注區域所造成之影響。顯示控制部，係產生於現在的前述病患之透視畫像中而重疊了前述影響度之資訊的顯示畫像，並使顯示部作顯示。
