Abstract
Disclosed herein are an X-ray imaging apparatus and a control method thereof in which a clear 3D volume of an object may be acquired when the 3D volume of the object is reconstructed from X-ray images acquired by radiating X-rays to the object. The X-ray imaging apparatus includes an image processing unit configured to acquire a plurality of X-ray images of an object from converted electrical signals, group the plurality of X-ray images into groups of X-ray images acquired from the same cardiac phase, and perform image reconstruction of each of the groups acquired as a result of the grouping.
Claims20
An X-ray imaging apparatus comprising:
- an image processing unit configured to acquire a plurality of X-ray images of an object from converted electrical signals, group the plurality of X-ray images into groups of X-ray images acquired from the same cardiac phase, and perform image reconstruction of each of the groups acquired as a result of the grouping.
A control method of an X-ray imaging apparatus, the control method comprising:
- radiating X-rays to an object from different positions using an X-ray generator;
- detecting X-rays transmitted through the object and converting the detected X-rays into electrical signals using an X-ray detector;
- acquiring a plurality of X-ray images of the object based on the converted electrical signals;
- grouping the plurality of X-ray images into groups of X-ray images acquired from the same cardiac phase;
- and
- performing image reconstruction of each of the groups acquired as a result of the grouping.
An imaging device, comprising:
- an X-ray generator configured to transmit X-rays towards a living object;
- an X-ray detector configured to detect a portion of the X-rays transmitted through the living object;
- and
- an image processor configured to generate X-ray images based on the detected X-rays and group the X-ray images into groups according to a cardiac cycle of the object.
