1. A method for fast three-dimensional (3D) visualization of object volumes without image reconstruction, the method comprising: acquiring a volumetric sensor 3D dataset from a scanner of a 3D N×N×N image of an object volume without image reconstruction; converting without image reconstruction the volumetric sensor 3D dataset into a radon space representation having radon coordinate dimensions of distance and angle Θ and axial plane position; slicing the radon space representation without image reconstruction to produce a stack of two-dimensional (2D) images expressed by radon space and axial plane dimensions; and, playing back the stack of 2D images in a movie player to provide a rotating view of the 3D object volume without a computational expense and image quality degradation resulting from image reconstruction.
