An object to be imaged is positioned between an x-ray source and an x-ray imager. The x-ray source is operated to direct x-rays through and around the object. Electrical signals representative of the intensity of the x-rays impinging on the x-ray imager are used to locate a boundary of the object, and an x-ray image is generated using this boundary. Alternatively or additionally, an x-ray image is generated using the highest frequency magnitude in the set of electrical signals. |
