-The process of matching the [[other:dsx:dsx_definitions#digitally_reconstructed_radiograph_drr|digitally reconstructed radiograph]] (DRR) images to the X-ray images is sensitive to the image processing parameters in the [[Other:DSX:X4D:X-ray_Windows|X-ray/DRR Settings]] widget. Once the DRR images have been generated for a particular set of bone poses the DRR images and the X-ray images are processed (using an identical method) and then compared to each other. The algorithm used to compare them, called the [[Other:DSX:X4D:X4D_Overview#Optimization_Metrics|image metric]], can be selected in the [[Other:DSX:X4D:Object_Tracking|Object Tracking]] widget.+The process of matching the [[other:dsx:dsx_definitions#digitally_reconstructed_radiograph_drr|digitally reconstructed radiograph]] (DRR) images to the X-ray images is sensitive to the image processing parameters in the [[other:dsx:x4d:x-ray_and_drr_settings|X-ray/DRR Settings]] widget.
