1. A method for generating an image of an object of interest, the method comprising: accessing a volumetric image of a space, the space including an object of interest and another object, the volumetric image comprising multiple voxels with at least one voxel representing the object of interest and at least one voxel representing the other object, wherein each voxel is associated with a numerical value; accessing a two-dimensional radiograph comprising data representing the object of interest and data representing the other object; identifying, in the volumetric image, a voxel representing the object of interest; setting a value associated with the identified voxel to a preset value; determining that the identified voxel is associated with the preset value; generating a de-objectified image by disregarding the identified voxel based on the determination; comparing the two-dimensional radiograph and the de-objectified image; and generating a two-dimensional image of the object of interest based on the comparison.
