Abstract
Provided is a method for applying filters for dental CT imaging, including: acquiring the dental CT imaging using a dental CT apparatus; extracting an artifact region from the acquired image; applying a first filter to a region other than the artifact region in the acquired image; and outputting the dental CT imaging to which the filter is applied. Dental CT imaging is provided without an artifact region to assist in medical treatment. More specifically, the dental CT imaging without the artifact region around the metal or tooth is able to be provided to assist in dental treatment. Further, the dental CT imaging without a white artifact region is able to be provided at a boundary portion of field of view (FOV) to assist in dental treatment.
Claims18
A method for applying filters for dental CT imaging, the method comprising:
- acquiring a dental CT image using a dental CT apparatus;
- extracting a region where an artifact is to occur from the acquired dental CT image;
- applying a first filter to a region other than the extracted region in the acquired dental CT image;
- and
- outputting the dental CT image in which the artifact is unshown after the first filter is applied,
- wherein the extracting of the region where the artifact is to occur includes applying a second filter to the acquired dental CT image and inverting a gray level of the dental CT image to which the second filter is applied.
A method for applying filters for dental CT imaging, the method comprising:
- acquiring a dental CT image using a dental CT apparatus;
- extracting a region where an artifact is to occur from the acquired dental CT image;
- applying a first filter to a region other than the extracted region in the acquired dental CT image;
- and
- outputting the dental CT image in which the artifact is unshown after the first filter is applied,
- wherein the extracting of the region where the artifact is to occur artifact region includes applying a third filter to the acquired dental CT image and inverting a gray level of the dental CT image to which the third filter is applied, and
- wherein the region where the artifact is to occur is corresponds to a region having the gray level exceeding a third value at a boundary of field of view (FOV) when the first filter is applied to the acquired dental CT image.
A system for applying filters for dental CT imaging, the system comprising at least one processor configured to:
- acquire a dental CT image using a dental CT apparatus;
- extract a region where an artifact is to occur from the acquired dental CT image;
- apply a first filter to a region other than the extracted region in the acquired dental CT image;
- and
- output the dental CT image in which the artifact is unshown after the first filter is applied,
- wherein the at least one processor is further configured to apply a second filter to the acquired dental CT image, and invert a gray level of the dental CT image to which the second filter is applied, to extract the region where the artifact is to occur.

- wherein the at least one processor is further configured to apply a third filter to the acquired dental CT image and invert a gray level of the dental CT image to which the third filter is applied, to extract the region where the artifact is to occur, and
- wherein the region where the artifact is to occur is a region having the gray level exceeding a third value at a boundary of field of view (FOV) when the first filter is applied to the acquired dental CT image.
