1. A system comprising:
a processor; and
a memory having stored thereon instructions, which, when executed by the processor, causes the processor to:
segment first two dimensional (2D) images based on pixels having intensities greater than a pixel intensity threshold, yielding segmented images;
dilate pixels of the segmented images, yielding dilated images;
compare groups of adjacent pixels in the dilated images to predetermined metal objects to recognize a metal object, yielding a recognized metal object;
remove pixels that do not form a portion of the recognized metal object from the dilated images;
generate first masks based on the dilated images;
apply the first masks to the first 2D images to remove pixels from the first 2D images, yielding second 2D images;
perform in-painting on the second 2D images in areas where the pixels are removed, yielding third 2D images; and
reconstruct a volume based on the third 2D images.
