Abstract:
Provided is an in vivo movement tracking apparatus configured to track a portion of interest that moves in vivo, in which accuracy and robustness of tracking are improved. The apparatus is configured to determine an estimated position of ah organ in a biological image based on the past movement of the organ and search for contour points corresponding to a plurality of control points, respectively, representing a contour shape of the organ in a region corresponding to the estimated position, to thereby determine an estimated contour of the organ based on the contour points. The in vivo movement tracking apparatus is configured to determine a position of a portion of interest, which moves in association with the organ, based on the estimated contour with reference to previously acquired sample data regarding a positional relationship between a contour of the organ and the portion of interest.

Claim (Index 2):
The in vivo movement tracking apparatus according to  claim 1 , therein the portion-of-interest tracking processing includes, in a position model representing the position of the portion of interest corresponding to a contour of interest of the organ of concern with a sum of a reference position and a linear combination of a plurality of displacement modes corresponding to the plurality of deformation modes:\n setting an average position of the portion of interest, which is based on the sample data, as the reference position; setting the coefficient in the linear combination of each of the plurality of deformation modes in the shape model corresponding to the contour of interest as a coefficient in the linear combination of each of the plurality of displacement modes; setting the plurality of displacement modes obtained by applying the position model to the sample data; and determining the position of the portion of interest corresponding to the estimated contour through use of the position model.
