|20140233041||Computerized Movable Laser System for Radiographic Patient Positioning - A system for radiographic patient positioning includes at least one laser. An orientation sensor is associated with a laser and the orientation sensor produces tilt data indicative of an orientation of a laser. A computer compares a later received tilt data from the orientation sensor to the stored tilt data to identify an error in the alignment of the laser. A method of operating a computer tomography patient positioning system includes providing a plurality of lasers and orientation sensors. A processor obtains tilt data from the orientation sensor of an associated laser and the tilt data is representative of an orientation of the associated laser. The processor compares new tilt data to the stored tilt data and identifies an error in an alignment of at least one laser of the plurality of laser units based upon the comparison of the new tilt data to the stored tilt data.||08-21-2014|
|20140133636||Computed Tomography Perfusion Phantom and Method Use Thereof - A computed tomography perfusion phantom includes a scanned plane configured to align with an imaging plane of a CT device. A sample rod extends through the scan plane and includes a plurality of adjacent cells. The plurality of adjacent cells are each constructed of materials having predetermined CT numbers and the plurality of adjacent cells include cell of a plurality of CT numbers. A drive motor is coupled to the sample rod and the drive motor moves the sample rod through the scan plane. A method of calibrating a CT device with the perfusion phantom includes aligning the scan plane of the perfusion phantom with an imaging plane of the CT device. The drive motor moves the sample rod through the scan plane of the perfusion phantom. A plurality of CT number measurements of the sample rod are acquired through the scanned plane of the perfusion phantom.||05-15-2014|
|20110001987||Variable Color Incoherent Alignment Line and Cross-Hair Generator - An alignment device includes an incoherent light source, a first convex lens, a mirror rod, and a second convex lens. The incoherent light source emits incoherent light that is received by the first convex lens that produces a low divergence light beam. The low divergence light beam is directed to the mirror rod that reflects the light beam to the second convex lens that focuses the light beam to a convergent light beam.||01-06-2011|
