Description

Bidirectionally flexible radiation detector The present invention relates to a radiation detector. Radiation imaging devices that acquire internal images of an object using radiation such as X-rays or gamma rays are used in various fields, including the medical and industrial sectors. Radiation imaging devices include a radiation source that generates radiation and a radiation detector that detects radiation that has passed through an object. Radiation detectors used to acquire images of objects such as pipes are commonly referred to as industrial radiation detectors. Since industrial radiation detectors must be able to perform imaging while positioned in close proximity to objects of various shapes, it is desirable for them to be manufactured in a flexible form. Radiation detectors configured for radiographic imaging for the non-destructive inspection of pipes must be capable of capturing both the inner and outer diameters of the pipe and must be designed to acquire and interpret images of the desired quality according to the application and imaging environment.
