摘要： Provided are a tomography imaging apparatus and a method of reconstructing a tomography image which may more accurately measure a motion of an object to be tomography-imaged. In detail, the tomography imaging apparatus and the method of reconstructing a tomography image may obtain information indicating a motion of a moving object according to a time, may perform motion correction based on the obtained motion information, and may reconstruct a target image with reduced motion artifacts.

摘要： 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.

摘要： A tomography imaging apparatus is provided, including: a data acquisition unit configured to acquire a plurality of partial data respectively corresponding to a plurality of consecutive angular sections by performing a tomography scan on a moving object; and an image processing unit configured to measure global motion of the object and motion of a first region in the object based on the plurality of partial data, acquire first information representing motion of the object by reflecting the global motion in the motion of the first region, and reconstruct a final tomography image representing the object based on the first information.
