1. A method for fast three-dimensional (3D) visualization of object volumes without image reconstruction, the method comprising: acquiring a 3D dataset from an scanner of a 3D object volume; converting the dataset into radon space representation; slicing converted dataset without image reconstruction to produce a sequence of two-dimensional (2D) of images in radon space; and, playing back the sequence of 2D images in a movie player to provide a rotating view of the 3D object volume.
