1. A method for making a three-dimensional image of an object, comprising:
providing an X-ray source on a first side of a object to be imaged;
positioning a substantially stationary X-ray detector on an opposite side of the object from the X-ray source;
moving the X-ray source in a circular motion to multiple positions on the first side of the object to create a conical geometry between the detector and the circular motion of the X-ray source, the cone having an angle θ that, for a given image depth, captures a full image of the object while reducing any blind spot behind the object;
collecting multiple two-dimensional (2D) images of the object when the X-ray source is located in the multiple positions; and
reconstructing a three-dimensional (3D) image using the multiple 2D images.
