1. A medical image processing device for making a display device display medical image information based on two or more different energy intensities obtained by irradiating an examinee with X-ray, characterized by comprising: statistic amount information acquiring means for acquiring statistic amount information corresponding to a type of a biomedical tissue of the examinee, for each energy intensity amongst the two or more different energy intensities; identification map creating means for creating an identification map for identifying the type of the biomedical tissue, on the basis of the statistic amount information, the identification map including areas corresponding to respective biomedical tissues; tissue identifying means for identifying the type of the biomedical tissue in the acquired medical image information on the basis of the identification map; identification probability map creating means that sets an identification probability value of the biomedical tissue on the basis of an existence probability value of the biomedical tissue and distance from a boundary of the type of the biomedical tissue to each point on the identification map, for each particular area on the identification map associated with a corresponding biomedical tissue, thereby creating an identification probability map representing an identification degree of the biomedical tissue; and display means for making the display device display an identification result of the tissue identifying means as the medical image information on the basis of the identification degree.
