Radiography apparatus and radiography method using same

Abstract

The present invention relates to a radiography apparatus and a radiography method using the same and, more particularly, to a radiography apparatus for capturing an image of an object by using radiation, and a radiography method using the same. The radiography apparatus according to an embodiment of the present invention comprises: a radiation emitting unit for emitting radiation at an object; a driving unit for moving the radiation emitting unit; a radiation detection unit for detecting radiation emitted from each of a plurality of capturing positions provided per capturing angle for the object, so as to acquire a plurality of radiation images; and a plurality of radiation sources provided in the radiation emitting unit, such that at least one thereof is arranged at one capturing positionand at least one thereof is arranged at a position spaced apart from each capturing position, according to the movement of the radiation emitting unit.

Description

technical field [0001] The present invention relates to a radiographic apparatus and a radiographic method using the same, and more particularly, to a radiographic apparatus that uses radiation to take an image of a target, and a radiographic method using the same The radiographic method of the equipment. Background technique [0002] Recently, as radiographic techniques have been applied to the semiconductor field, the radiographic techniques have rapidly developed into digital imaging techniques with advantages such as relatively high resolution, dynamic Wide area, easy to generate electrical signals and convenient data processing and storage. Digital imaging technology strongly reflects the need for early diagnosis of disease in a clinical environment that relies on the excellent diagnostic capabilities of digital images. [0003] Therefore, a digital mammography technique was introduced, which is a radiographic technique specifically for the breast, which utilizes the ...

Problems solved by technology

[0006] In this conventional radiography apparatus, there occurs a phenomenon of motion blur, that is, the boundary of an image acquired by the radiation detection unit cannot be clearly shown due to the movement of the radiation source, and thus the image quality is degraded

To prevent this motion blur phenomenon, a stop and shoot method is also used: the radiation source in a completely stopped state takes the projected image at an angle for imaging, and then moves the radiation source to the next position for imaging ; however, since in this method the radiation source should perform imaging in a state of complete stop, there is a problem of total imaging time delay
