PROBLEM TO BE SOLVED: To provide a trabecula analyzer capable of more accurately executing trabecula analysis based on a two-dimensional image.SOLUTION: A texture analysis index t1 obtained by performing image analysis on a tomographic image Da is a parameter which varies depending on a state of a trabecula, and does not accurately show the state of the trabecula because a state of a three-dimensional structure of the trabecula is not considered. Estimation of an evaluation value obtained in the case of presuming that a subject in the tomographic image Da is three-dimensionally analyzed is performed on the basis of the texture analysis index t1 obtained from the tomographic image Da. Thereby, the texture analysis index easily obtained from the tomographic image Da makes it possible to provide a trabecula analyzer capable of understanding of an accurate state of a trabecula which is impossible in a conventional art.
