Abstract:
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.

PROBLEM TO BE SOLVED: To provide an apparatus and a method for acquiring an optimal multi-energy X-ray image.SOLUTION: An apparatus for acquiring a multi-energy X-ray image includes an X-ray source to generate an X-ray and to irradiate the X-ray, an energy identification detector to acquire a multi-energy X-ray image that is generated when the irradiated X-ray penetrates an imaging object, and a multi-energy X-ray processor to generate an optimal multi-energy X-ray imaging parameter based on a characteristic of the imaging object and to control at least one of the X-ray source and the energy identification detector based on the generated optimal multi-energy X-ray parameter.
Abstract:
An image processing system and method are provided to adaptively discriminate hard tissues and soft tissues of a target in a multi-energy X-ray system. The image processing system and method may minimize a decrease in a dynamic range (DR) for soft tissues affected by hard tissues in a target where the soft tissues and hard tissues are mixed.
Abstract:
Disclosed are a multi-energy X-ray system, an image processing apparatus for discriminating a multi-energy X-ray material, and an image processing method for material discrimination of a multi-energy X-ray system. The image processing apparatus for discriminating a multi-energy X-ray material according to one aspect of the present invention comprises: a table for recording attenuation information and multi-energy X-ray spectrum information which correspond to one or more materials; an initial image estimating portion for estimating an initial image of each of the materials with respect to a projection image of each of the energy bands generated when a multi-energy X-ray spectrum passes through a detecting target formed with one or more materials; and an image update portion for updating the initial image as the material discrimination image using the estimated initial image and the spectrum information recorded in the table and the attenuation information recorded in the table.
Abstract:
A method of determining a pose of a target object in a query image may include: obtaining a query image; obtaining a plurality of reference images corresponding to the query image; and determining a pose of a target object based on a first semantic feature corresponding to the query image and a second semantic feature corresponding to each of the plurality of reference images.
