Description

Imaging apparatus and method using radioactive radar The embodiments disclosed in this document relate to a radiographic device and a radiographic method. Generally, devices that utilize radiation to acquire internal images of objects are used across various industrial and medical fields. These devices are called CT (Computer Tomography) and can visualize information regarding the internal structure or tissue condition of an object in the form of images. In particular, petrochemical facilities have many areas where diagnosis is possible by acquiring internal images using radiation, such as distillation towers, fixed-bed reactors, and process piping, and some technologies, such as gamma-ray distillation tower inspection, are currently being commercialized. FIG. 1 is a block diagram of a radiographic device according to one embodiment disclosed in this document. FIG. 2a is a drawing showing an example of photographing an object using a radiographic device according to one embodiment disclosed in this document. FIG. 2b is a drawing showing an example of image information according to one embodiment disclosed in this document. FIG. 3 is a drawing showing the configuration of a seaman according to one embodiment disclosed in this document. FIG. 4 is a drawing showing the configuration of a detection unit according to one embodiment disclosed in this document. FIG. 5 is a flowchart illustrating a radiographic imaging method according to one embodiment disclosed in this document. Hereinafter, various embodiments of the present invention are described with reference to the accompanying drawings. However, this is not intended to limit the present invention to specific embodiments and should be understood to include various modifications, equivalents, and/or alternatives of the embodiments of the present invention. In this document, the singular form of a noun corresponding to an item may include one or more of said items unless the relevant context clearly indicates otherwise. In this document, phrases such as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B or C,” “at least one of A, B and C,” and “at least one of A, B, or C” may each include any one of the items listed together in the corresponding phrase, or all possible combinations thereof. Terms such as “first,” “second,” or “first” or “second” may be used simply to distinguish a component from another corresponding component and do not limit the components in any other aspect (e.g., importance or order). Where any (e.g., 1st) component is referred to as “coupled” or “connected” to another (e.g., 2nd) component, with or without the terms “functionally” or “communicationly,” it means that said any component may be connected to said other component directly (e.g., via a wire), wirelessly, or through a third component.
