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.

Apparatus and method for visualization

A shape data generation apparatus includes a detection unit and a generation unit. With reference to model information indicating the thicknesses and the positions of both ends of a plurality of elements each having a cylindrical surface, the detection unit detects a connection point where two or more elements are connected to each other, on the basis of the positions of both ends of the elements. The generation unit generates a curved surface collectively covering the connecting ends of the two or more elements, on the basis of the thicknesses and the positions of both ends of the two or more elements connected at the connection point.

Apparatus and method for generating shape data

A magnetization analysis apparatus includes a processor configured to execute a process. The process includes: first calculating, using a magnetization vector of each of elements obtained by mesh division in which a magnetic substance is divided into a plurality of meshes and a magnetization vector of an element adjacent to each element, intermediate magnetization that is a magnetization vector at the halfway point between each element and an element adjacent to each element; second calculating an effective magnetic field using the intermediate magnetization calculated at the first calculating; and third calculating a magnetization vector of each element after a unit time based on the effective magnetic field calculated at the second calculating.

A disclosed method includes: performing a processing for adjusting positions of voxel data for an object and data of a geometric model for the object; calculating, for each voxel included in a range defined by a cross section among plural voxels that are included in the voxel data, a voxel value of the voxel from physical values in elements of the geometric model, which are included in a predetermined range of the voxel, based on a relation between the cross section and vectors; and rendering an image by using the voxel value calculated for each voxel. A vector of the vectors is set for one element of plural elements included in the geometric model, the vectors represent a direction of an inner structure of the object, and the cross section is set for the voxel data and the geometric model data.
