Abstract
A collimator for adjusting the shape of a region irradiated by radiation and a control method thereof. The collimator includes a plurality of irises to adjust the shape of the irradiation region, a light source outputting light to display the irradiation region, a reflective mirror to adjust a path of light radiated from the light source toward the irradiation region, and an image output unit outputting to the irradiation region a visible image representing the shape of a target object for radiography or a mark indicating the center of the radiation region.
Claims23
A collimator for adjusting an irradiation field of radiation to be used for radiography, comprising:
- a plurality of irises for adjusting a shape of a radiation path of X-rays and an irradiation region onto which the X-rays are radiated;
- a light source outputting visible light to display the irradiation region;
- a reflective mirror to adjust a path of light radiated from the light source;
- and
- an image output unit responsive to visible light output from the light source for outputting data in accordance with a user selection representing a designated image showing a representative shape of a target object for radiography.
A method of control of a collimator for adjusting an X-ray irradiation region of radiation, the control method comprising:
- determining an image corresponding to a target object for radiography, in response to input of information about the object;
- outputting visible light to show an X-ray irradiation region;
- and
- transmitting a control signal to a display unit to cause the display unit to visibly display in accordance with a user selection a designated image comprising the visible light showing a representative shape of the target object for radiography.
