Abstract
An imaging method includes calculating a derivative back projection (DBP) result value using a DBP method with respect to a projection image of a field of view (FOV) inside an object, and reconstructing an image of the FOV by applying a regulation function to the FOV while reconstructing the image of the FOV using the DBP result value.
Claims19
A method of reconstructing an image, comprising:
- calculating a derivative back projection (DBP) result value using a DBP method with respect to a projection image of a field of view (FOV) inside an object;
- and
- reconstructing an image of the FOV by using the DBP result value, and further using a regulation function which defines an internal luminance value of the FOV inside the object.
An X-ray imaging apparatus comprising:
- an X-ray radiator configured to irradiate a field of view (FOV) inside an object with X-rays;
- an X-ray detector configured to output electrical signals by converting the X-rays having passed through the FOV;
- and
- an image processor configured to acquire a projection image of the FOV inside the object based on the electrical signals, calculate a derivative back projection (DBP) result value using a DBP method with respect to the projection image, and reconstruct an image of the FOV by using the DBP result value and a regulation function which defines an internal luminance value of the FOV inside the object.
