Embodiments of the present invention address deficiencies of the art in respect to 3D visualization of object volumes and provide a method, system and computer program product for fast 3D visualization of object volumes without image reconstruction by direct display of acquired sensor data. In an embodiment of the invention, a method for fast 3D visualization of object volumes without image reconstruction can be provided. The method can include acquiring a 3D dataset from an scanner of a 3D object volume, slicing the acquired sensor data without image reconstruction to produce a sequence of 2D 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.
