RECONSTRUCTION OF TIME-VARYING DATA |
| 摘要 |
Systems and methods are provided for data reconstruction. In accordance with one aspect, data interpolation is performed on a time-varying three-dimensional (3D) image dataset of one or more vessel-like structures to generate at least one interpolated voxel value. The interpolated voxel value is used to correct at least one value of a vessel voxel representing the one or more vessel-like structures in the time-varying 3D dataset. |

1. A non-transitory computer readable medium embodying a program of instructions executable by machine to perform steps for facilitating iterative data reconstruction, the steps comprising:
(i) receiving a time-varying two-dimensional (2D) image dataset of one or more vessel-like structures; (ii) forward projecting temporal volumes in a current estimated time-varying three-dimensional (3D) dataset and determining an error between the current estimated time-varying 3D dataset and corresponding projection data from the time-varying 2D image dataset; (iii) back projecting the error across the temporal volumes in the current estimated time-varying 3D dataset; (iv) applying a regularization function to the current estimated time-varying 3D dataset; and (v) repeating at least steps (ii), (iii) and (iv) until a terminating condition is met. |
