20110251480 | Movable Integrated Scanner for Surgical Imaging Applications - A patient imaging system includes a patient support table, an MRI system including a cylindrical magnet and a PET system including positron detectors mounted in a ring. The magnet defines a cylindrical bore for receiving the patient on the table where the magnet is mounted for rotation about a vertical axis on a slew ring carried on rails allowing longitudinal movement. The PET ring is mounted in the bore for longitudinal movement. The quench tube for the magnet passes through the slew ring with a rotary union at the axis. The shielding covers include a fixed upper part and a lower part which rotates about the axis with the magnet. The magnet is arranged in a two or three room diagnostic configuration in which a holding bay houses the magnet and the diagnostic patients are organized in the three rooms each cooperating with the magnet bay as the magnet is rotated. | 10-13-2011 |

20090244072 | Method for correct reproduction of moving spatial images on a flat screen - A method for correct reproduction of moving three-dimensional (3D) scenes observed by a viewer on displays showing moving three-dimensional scenes relating to video games, animated cartoons, simulators for drivers or pilots, etc. The main concept of the invention is the reproduction of a moving scene that rotates around a selected center, which is the point of the viewer's gaze fixation. Thus, all objects that are stationary with respect to each other on the illustrated scene rotate at the same angular speed but move on the screen at different linear speeds, which are inversely proportional to preselected distances from the viewer to the respective objects. Movements of objects relative to each other are presented in a coordinate system rotating with the scene. For reproduction on the display, distances to the objects, number of objects, and other selected data are entered into a conventional 3D-animation computer program. | 10-01-2009 |
