Abstract
A method for reconstructing an image may include obtaining scan data relating to a subject. The method may also include determining a first field of view (FOV) and determining a second FOV. The method may further include reconstructing a first image based on a first portion of the scan data corresponding to the first field of view, and reconstructing a second image based on a second portion of the scan data corresponding to the second field of view. The method may also include generating a third image based on the first image and the second image.
Claims23
A method, comprising:
- obtaining scan data relating to a subject;
- determining a first field of view;
- determining a second field of view;
- reconstructing a first image based on a first portion of the scan data corresponding to the first field of view;
- reconstructing a second image based on a second portion of the scan data corresponding to the second field of view;
- and
- generating a third image based on the first image and the second image.
A system, comprising:
- a data acquisition module configured to obtain scan data relating to a subject;
- a FOV determination unit configured to determine a first field of view and a second field of view;
- a weighting function determination unit configured to determine a first portion of the scan data corresponding to the first field of view and a second portion of the scan data corresponding to the second field of view;
- and
- an image generation unit configured to reconstruct a first image based on the first portion of the scan data, a second image based on the second portion of the scan data, and a third image based on the first image and the second image.
