PROBLEM TO BE SOLVED: To provide handheld imaging systems and methods for using the systems to create a 3D image of a desired object by using scattered radiation.SOLUTION: The handheld imaging apparatus can comprise a housing, a radiation source for irradiating an object with a fan beam or cone beam, and multiple detector elements for detecting backscattered radiation from the object, where each detector element has a different view of the object and collects a different image of the object than the other detector elements. Alternatively, the handheld imaging apparatus can comprise a housing, a radiation source for irradiating an object with a pencil beam of radiation, and a detector configured to detect backscattered radiation from the object, where the detector and the radiation source are oriented off-axis relative to each other. The handheld imaging apparatus are used to irradiate a desired object with radiation to obtain multiple two dimensional images of the object and then creates a three dimensional image of the object by using the multiple two dimensional images. |
