Radiographic device and radiographic method using same

A radiographic device comprising:

• an X-ray irradiator radiating X-rays;
• an image acquisition unit acquiring an image by receiving the X-rays which are radiated from the radiation irradiator and pass through an irradiation target object;
• a C arm supporting the X-ray irradiator and the image acquisition unit;
• a driving unit driving the C arm;
• a position information detector detecting position information of at least one of driving elements of the driving unit of the C arm;
• a storage unit setting position information in which an image is captured by the X-ray irradiator and the image acquisition unit as reference position information, associating the reference position information and X-ray output information in which the image is captured, and storing the associated information as positioning information;
• and
• a determination controller controlling an operation of the X-ray radiator based on the position information detected by the position information detector,
• wherein the determination controller performs an operation of associating the X-ray output information for driving the X-ray irradiator to capture the image when the image is captured by the X-ray irradiator and the image acquisition unit and the reference position information indicating a position at which the image is captured and storing the associated information as the positioning information, and an operation of, when the position information of the driving element detected by the position information detector matches any one piece of reference position information of the positioning information, controlling the X-ray irradiator to be driven under an X-ray output condition according to the X-ray output information associated with the reference position information so that the image is captured,
• wherein the positioning information further includes a radiographic image acquired at a position of the reference position information.

A radiographic method, which is performed using a radiographic device including a radiation irradiator radiating radiation, and an image acquisition unit acquiring an image by receiving the radiation which is radiated from the radiation irradiator and penetrates an irradiation target object, the radiographic method comprising:

• associating reference position information indicating a position of the radiation irradiator during radiography and radiation output information including a driving condition of the radiation irradiator with each other and storing the associated information in a storage unit as positioning information;
• determining whether position information indicating a position of the radiation irradiator detected in real time matches any one piece of reference position information in the positioning information stored in the storage unit;
• and
• when the detected position information matches the reference position information in the positioning information, controlling the radiation irradiator to be driven according to the radiation output information associated with the reference position information so that an image is captured,
• wherein the positioning information further includes a radiographic image captured according to the radiation output information at a reference position.
