A computing device in a three-dimensional imaging system utilizes a plurality of distance readings and reference readings from the at least one subject sensor to determine a subject location and a subject volume and establish a base-three dimensional map of a subject. A base-three dimensional map may be pre-existing. A plurality of two-dimensional image exposures along with a plurality of associated reference locations are created by utilizing an image source and an image receptor around an inner circumference of an imaging gantry. The plurality of two-dimensional image exposures is digitized to create a plurality of digital two-dimensional image exposures. The computing device receives the plurality of digital two-dimensional image exposures and the plurality of associated reference locations. The overlaying, interpolating, and pasting of the plurality of digital two-dimensional image exposures on the base three-dimensional map creates a base three-dimensional image exposure, which is displayed on a display device.
