Abstract
A radiographic imaging apparatus includes: a radiographic image obtainer configured to acquire a first radiographic image of an object; and a processor configured to obtain attenuation information of the object based on the first radiographic image, determine candidate tube voltages and tube currents based on a quality of a second radiographic image to be obtained, and determine expected exposure doses corresponding to the determined candidate tube voltages and tube currents.

A radiographic imaging apparatus comprising:
- a radiographic image obtainer configured to acquire a first radiographic image of an object;
- and
- a processor configured to obtain attenuation information of the object based on the first radiographic image, determine candidate tube voltages and candidate tube currents based on a quality of a second radiographic image to be obtained, and determine expected exposure doses corresponding to the determined candidate tube voltages and tube currents.
A method of controlling a radiographic imaging apparatus, the method comprising:
- obtaining a radiographic image of an object;
- obtaining attenuation information of the object based on the radiographic image;
- determining candidate tube voltages and candidate tube currents based on set quality of an image;
- and
- determining expected exposure doses corresponding to the obtained candidate tube voltages and tube currents.
A computed tomography (CT) apparatus comprising:
- a gantry;
- a radiation source which is installed in the gantry and configured to irradiate an object with radiographic rays;
- a radiographic detector which is installed in the gantry, and is configured to receive the radiographic rays transmitted through the object and output electrical signals corresponding to the received radiographic rays;
- an image processor configured to obtain a first radiographic image based on the output electrical signals;
- and
- a processor configured to obtain attenuation information of the object based on the first radiographic image, determine candidate tube voltages and candidate tube currents based on quality of a second radiographic image to be obtained, and determine expected exposure doses corresponding to the candidate tube voltages and tube currents.
