Abstract
Methods and systems are described for removing reflective artifacts from an imaging model. An x-ray detector captures x-ray images that include a structure and an imaging device captures a surface scan of the same structure. An image processor constructs a three-dimensional CT model of the structure from the x-ray images and constructs a three-dimensional surface model of the structure from the surface scan. The image processor is configured to resize and orient the surface model and/or the CT model so that they are the same scale and orientation, overlay the surface model onto the CT model, and detect data points in the combined data set that extend beyond a surface of the structure in the surface model. The detected data points represent artifacts in the CT model and are adjusted by interpolation to produce an artifact-reduced CT model.
