Abstract
A local high-resolution imaging method and apparatus for a three-dimensional (3D) skeletal image is provided. The method includes determining a volume of interest (VOI) to perform high-resolution imaging from the 3D skeletal image in which an object to be inspected is captured, localizing the VOI based on a finite element method (FEM), and setting a multi-resolution constraint based on a bone mineral density (BMD) between the 3D skeletal image and the localized VOI and reconstructing a skeletal image in which high-resolution imaging is performed on the localized VOI.

A local high-resolution imaging method for a three-dimensional (3D) skeletal image, the method comprising:
- determining a volume of interest (VOI) to perform high-resolution imaging on the 3D skeletal image in which an object to be inspected is captured;
- localizing the VOI based on a finite element method (FEM);
- and
- setting a multi-resolution constraint based on a bone mineral density (BMD) between the 3D skeletal image and the localized VOI and reconstructing a skeletal image in which high-resolution imaging is performed on the localized VOI.
A local high-resolution imaging apparatus for a 3D skeletal image, the apparatus comprising:
- a VOI determining unit configured to determine a VOI to perform high-resolution imaging on the 3D skeletal image in which an object to be inspected is captured;
- a VOI localizing unit configured to localize the VOI based on an FEM;
- and
- an image reconstructing unit configured to set a multi-resolution constraint based on a BMD between the 3D skeletal image and the localized VOI and to reconstruct a skeletal image in which high-resolution imaging is performed on the localized VOI.
A local high-resolution imaging apparatus for a 3D skeletal image, the apparatus comprising:
- a memory into which at least one program is loaded;
- and
- at least one processor,
- wherein the at least one processor determines a VOI to perform high-resolution imaging on the 3D skeletal image in which an object to be inspected is captured, localizes the VOI based on an FEM, and sets a multi-resolution constraint based on a BMD between the 3D skeletal image and the localized VOI and reconstructs a skeletal image in which high-resolution imaging is performed on the localized VOI, under control of the at least one program.
A computer-readable storage medium comprising instructions for controlling a computer system to perform high-resolution imaging of a 3D skeletal image, the instructions controlling the computer system by a method, the method comprising:
- determining a VOI to perform the high-resolution imaging on the 3D skeletal image in which an object to be inspected is captured;
- localizing the VOI based on an FEM;
- and
- setting a multi-resolution constraint based on a BMD between the 3D skeletal image and the localized VOI and reconstructing a skeletal image in which high-resolution imaging is performed on the localized VOI.
