摘要： Based on heart behavior data, a computation unit determines a first time step at which a heart exhibits a first behavior in response to a first wave of an electrical signal, as well as a second time step at which the heart exhibits a second behavior in response to a second wave of the same. The computation unit reproduces the heart's behavior over time by updating a three-dimensional model of the heart according to the heart behavior data, simultaneously with variations in electrical signal strength over time according to electrocardiogram data. The computation unit coordinates this reproduction such that a first shape of the heart at the first time is reproduced step simultaneously with the first wave of the electrical signal, and such that a second shape of the heart at the second time step is reproduced simultaneously with the second wave of the electrical signal.

摘要： A biological model creation apparatus sets a plurality of control points respectively corresponding to a plurality of target points set on a plurality of valve annuli of a specified heart, on a plurality of valve annuli in a mesh model of a heart. Then, the biological model creation apparatus determines the positions of the control points in the mesh model on the basis of a first and second evaluation value regarding the positions of the plurality of control points. The first evaluation value indicates a degree of matching to relative positions among target points belonging to the same valve annulus. The second evaluation value indicates a degree of matching to relative positions among target points belonging to different valve annuli. Then, the biological model creation apparatus deforms the mesh model such that the positions of the plurality of control points coincide with the positions of their corresponding target points.

摘要： A streakline visualization apparatus sets a partial region including a discrete point at a first position on a first streakline in an analysis space as an analysis target region of the discrete point. Based on a velocity of fluid in the analysis target region indicated by fluid information, the apparatus calculates a second position indicating a destination of a particle on the discrete point at a second analysis time point. Next, based on information about a structure in the analysis target region indicated by structure information, the apparatus determines a region occupied by the structure in the analysis target region at the second analysis time point. Next, based on the first and second positions, the apparatus determines whether a second streakline has entered the occupied region. If the second streakline has not entered the occupied region, the apparatus displays the second streakline passing through the second position.
