Abstract
A tomography apparatus includes a data obtainer and an image processor. The data obtainer performs a tomography scan on a moving object and obtains raw data of the object The image processor reconstructs a first tomography image of the object for a first slice section in a first phase from the raw data and reconstructs a second tomography image in a second phase, which is different from the first phase, for the first slice section of the object by using the raw data. The image processor also generates motion information indicating a three-dimensional (3D) motion of the object. The second phase is a phase beyond a phase range of the raw data.

A tomography apparatus comprising:
- a data obtainer configured to perform a tomography scan on a moving object and obtain raw data of the object;
- and
- an image processor configured to:
- reconstruct a first tomography image of the object for a first slice section in a first phase from the raw data;
- and
- reconstruct a second tomography image in a second phase, which is different from the first phase, for the first slice section of the object by using the raw data and motion information indicating a three-dimensional (3D) motion of the object,
- wherein the second phase is a phase beyond a phase range of the raw data.
A method of reconstructing a tomography image, the method comprising:
- performing a tomography scan on a moving object and obtaining raw data of the object;
- reconstructing a first tomography image of the object for a first slice section in a first phase from the raw data;
- and
- reconstructing a second tomography image in a second phase, which is different from the first phase, for the first slice section of the object by using the raw data and motion information indicating a three-dimensional (3D) motion of the object,
