1. A method for generating a two-dimensional image of an object using a CT scanner, said method comprising: selecting an imaging surface for the object, the imaging surface including a plurality of pixels; selecting a viewing direction that is non-parallel to the imaging surface; rotating an x-ray source of the CT scanner around the object through a plurality of views, wherein the x-ray source projects x-rays towards a detector array opposite the x-ray source; for each pixel of the plurality of pixels: acquiring using the detector array, from the plurality of views, data values for x-rays that pass through the pixel and are within a pre-determined angle from parallel to the viewing direction; and combining, using a processing device, the data values acquired for the pixel while excluding other data values that do not correspond to the x-rays that pass through the pixel and are within the pre-determined angle to calculate a final value for the pixel; and generating the two-dimensional image of the object based on the calculated final values for each pixel.
