Abstract: The preparation of a 72Se/72As radioisotope generator involves forming an acidic aqueous solution of an irradiated alkali bromide target such as a NaBr target, oxidizing soluble bromide in the solution to elemental bromine, removing the elemental bromine, evaporating the resulting solution to a residue, removing hydrogen chloride from the residue, forming an acidic aqueous solution of the residue, adding a chelator that selectively forms a chelation complex with selenium, and extracting the chelation complex from the acidic aqueous solution into an organic phase. As the 72Se generates 72As in the organic phase, the 72As may be extracted repeatedly from the organic phase with an aqueous acid solution.

Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on an organ of interest of a patient during a scan, such as an MRI scan. The marker allows measuring the six degrees of freedom or “pose” required to track motion of the organ of interest. A detector, preferably a camera, observes the marker and continuously extracts its pose. The pose from the camera is sent to the scanner via an RGR processing computer and a scanner control and processing computer, allowing for continuous correction of scan planes and position (in real-time) for motion of the patient. This invention also provides for internal calibration and for co-registration over time of the scanner's and tracking system's reference frames to compensate for drift and other inaccuracies that may arise over time.

Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker (30), preferably a retro-grate reflector (RGR), is placed on the head or other body organ of interest of a patient (P) during a scan, such as an MRI scan. The marker (30) makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track motion of the organ of interest. A detector, preferably a camera (40), observes the marker (30) and continuously extracts its pose. The pose from the camera (40) is sent to the scanner (120) via an RGR processing computer (50) and a scanner control and processing computer (100), allowing for continuous correction of scan planes and position (in real-time) for motion of the patient (P).

Abstract: Current MRI technologies require subjects to remain largely motionless for achieving high quality magnetic resonance (MR) scans, typically for 5-10 minutes at a time. However, lying absolutely still inside the tight MR imager (MRI) tunnel is a difficult task, especially for children, very sick patients, or the mentally ill. Even motion ranging less than 1 mm or 1 degree can corrupt a scan. This invention involves a system that adaptively compensates for subject motion in real-time. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on a patients' head or other body organ of interest during MRI. The RGR makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track the organ of interest. A camera-based tracking system observes the marker and continuously extracts its pose.

Abstract: An interactive system and method automates the control and management of routing changes that are focused on specific routes or particular network hot spots. Based on the premise that the user is aware of a particular problem that needs to be solved, the system leads the user through an end-to-end process from the identification of the problem to the generation of configuration instructions for effecting a selected solution. A graphic user interface provides a visualization of the current routing and alternative routings, to facilitate the analysis and selection of an improved routing, if any. Throughout the process, the effect of each proposed routing change on the overall network performance is determined, so that the selection of a preferred solution can be made in the appropriate context, and globally sub-optimal solutions can be avoided.

Abstract: A system for illuminating panels such as advertising display panels is provided. Such illuminated panels can be operated very efficiently, cost-effectively and with minimal maintenance once installed in the field. In one embodiment, the illuminated panel includes a panel frame with one or more illuminated frame member. Additional illuminated frame member(s) may be needed depending on the overall dimensions of the illuminated panel. The inside surface of the illuminated frame member should be reflective to increase the light transmission efficiency of the panel. A row of point light sources, e.g., a row of light emitting diodes, is located within the illuminated frame member. The panel frame encloses a light diffusion layer, e.g., an acrylic sheet, with a diffusion edge facing the row of point light sources. The diffusion edge has a surface roughness configured to diffuse light emitted by the row of point light sources.
