MOTION PARAMETER ESTIMATION |
| 摘要 |
An object motion parameter determiner (122) includes a deformation vector field determiner (210) that determines deformation vector fields for a 4D image set, which includes three or more images corresponding to three or more different motion phases of motion of a moving object. The object motion parameter determiner further includes a volume curve determiner (212) that generates a volume curve for the voxel based on the deformation vector fields. The object motion parameter determiner further includes a model fitter (214) that fits a predetermined motion model to the volume curve. The object motion parameter determiner further includes a parameter determiner (218) that estimates at least one object motion parameter based on the fitted model. |

1. An object motion parameter determiner, comprising:
a deformation vector field determiner that determines deformation vector fields for a 4D image set, which includes three or more images corresponding to three or more different motion phases of motion of a moving object; a volume curve determiner that generates a volume curve for a voxel based on the deformation vector fields; a model fitter that fits a predetermined motion model to the volume curve; and a parameter determiner that estimates at least one object motion parameter based on the fitted model. |
