Abstract
A tomography apparatus that may reduce partial scan artifacts includes: a data acquirer configured to acquire tomography data when X-rays are emitted as a cone beam to an object while rotating by one cycle angular section that is less than one rotation; and an image reconstructor configured to reconstruct a tomography image by using corrected tomography data that is obtained by applying to the tomography data a weight that is set based on at least one of a view that is included in the one cycle angular section and a cone angle in the cone beam.
Claims15
A tomography apparatus comprising:
- a data acquirer configured to acquire tomography data when X-rays are emitted as a cone beam to an object while rotating by one cycle angular section that is less than one rotation;
- and
- an image reconstructor configured to reconstruct a tomography image by using corrected tomography data that is acquired by applying to the tomography data a weight that is set based on at least one of a view that is included in the one cycle angular section and a cone angle in the cone beam.
A method of reconstructing a tomography image, the method comprising:
- when X-rays that are emitted as a cone beam to an object while rotating by one cycle angular section that is less than one rotation, acquiring tomography data;
- acquiring a weight based on at least one of a view that is included in the one cycle angular section and a cone angle in the cone beam;
- and
- reconstructing a tomography image by using corrected tomography data that is acquired by applying the weight to the tomography data.
The method of claim 16, wherein the reconstructing of the tomography image further comprises
- reconstructing the tomography image by compensating for artifacts that occur due to a difference between data in a first view that is included in the one cycle angular section and data in a second view that faces the first view in the tomography data by using the weight.
