Method and system of processing multi-energy X-ray images

摘要

Provided is a method and system of processing a multi-energy X-ray image. Through the method and system, a plurality of target images may be acquired using an X-ray detector enabling an energy separation to be performed in a predetermined time interval, with respect to a target where a contrast agent is applied, and a signal processing may be performed on the acquired target images, thereby detecting and reading benign/malignant lesions or masses.

主权项

1. A method of processing a multi-energy X-ray image, the method comprising:
acquiring, in a predetermined time interval, a plurality of target images for each of at least two energy bands formed by a multi-energy X-ray after passing through a target where a contrast agent is applied, from a multi-energy X-ray source; and performing an image signal processing on the plurality of target images, further comprising: estimating respective initial images for at least one of plural materials, over the predetermined time interval, using the plurality of target images; updating an initial estimated image of the estimated respective initial images based on, at least, one of later estimated images of the estimated respective initial images for the at least one of plural materials; and generating a material decomposition image based on the updating of the initial estimated image.
