Abstract
An X-ray imaging apparatus and method are provided. The X-ray imaging apparatus according to an aspect includes an X-ray source configured to radiate X-rays onto a subject region, an X-ray detector configured to detect the radiated X-rays and obtain a plurality of frame images of the subject region, and an ROI filter located between the X-ray source and the X-ray detector, configured to move toward the X-ray source and the X-ray detector, and configured to filter the X-rays radiated from the X-ray source.
Claims20
An X-ray imaging apparatus, comprising:
- an X-ray source configured to radiate X-rays onto a subject region;
- an X-ray detector configured to detect the radiated X-rays, and obtain a plurality of frame images of the subject region, based on the detected X-rays;
- a collimator disposed between the X-ray source and the X-ray detector, and configured to adjust a range of the subject region;
- and
- a region of interest (ROI) filter disposed between the collimator and the X-ray detector, and configured to filter the X-rays radiated from the X-ray source, the ROI filter comprising a plurality of filter layers,
- wherein a first filter layer among the plurality of filter layers is configured to be disposed above a second filter layer among the plurality of filter layers and along a line orthogonal to surfaces respectively of the collimator and the X-ray detector, the surfaces face each other, and each of the plurality of filter layers is configured to be independently translatable in a direction along the line toward the collimator or the X-ray detector.
A method of controlling an X-ray imaging apparatus, the method comprising:
- controlling an X-ray source to radiate X-rays onto a subject region;
- adjusting a range of the subject region, using a collimator;
- detecting, by an X-ray detector, the radiated X-rays;
- obtaining information of a region of interest (ROI) inside of the subject region, based on the detected X-rays;
- and
- controlling an ROI filter configured to filter X-rays incident on a non-ROI inside of the subject region, based on a movement of the ROI or a size of the ROI, the ROI filter being disposed between the collimator and the X-ray detector, and the ROI filter comprising a plurality of filter layers,
- wherein a first filter layer among the plurality of filter layers is disposable above a second filter layer among the plurality of filter layers and along a line orthogonal to surfaces respectively of the collimator and the X-ray detector, the surfaces face each other, and each of the plurality of filter layers is independently translatable in a direction along the line toward the collimator or the X-ray detector.
