Abstract
Provided is a method and apparatus for metal artifact reduction in industrial three-dimensional (3D) cone beam computed tomography (CBCT) that may align computer-aided design (CAD) data to correspond to CT data, generate registration data from the aligned CAD data, set a sinogram surgery region corresponding to a metal region based on the registration data, perform an average fill-in process on the CT data based on the registration data, update data of the sinogram surgery region based on the averaged filled-in information, and reconstruct a 3D CT image from the updated sinogram data with surgery region.
Claims17
An operation method of an electronic device, the method comprising:
- generating registered computer-aided design (CAD) volume data, which matches to computed tomography (CT) volume data, based on prepared CT data and prepared CAD data;
- generating a CT image by updating a sinogram surgery region based on the registration data;
- downsampling the CAD data;
- and
- obtaining the registration parameters for the downsampled data by performing a registration process on the downsampled CAD data.
An electronic device comprising:
- a registration module configured to register computer-aided design (CAD) data by aligning prepared CAD data to prepared computed tomography (CT) data;
- and
- a module configured to generate a CT image based on the registration data;
- wherein the registration module is further configured to downsample the CAD data, and to obtain the registration parameters for the downsampled data by performing a registration process on the downsampled CAD data.
