摘要： A method and apparatus for producing radioactive transmission measurements to form multi-dimensional attenuation correction data with a point source of radiation, such as required in positron emission tomography applications. This involves the passing of the point source proximate the face of a selected each of the tomograph units for the formation of a 3-D image, or a selected portion of the tomograph units for a 2-D image. As such, attenuation data, transmission data, detector performance data, etc., can be obtained. This point source of radiation, in one embodiment, is rapidly circulated through a conduit that passes across each detector face under the influence of a transport fluid in, for example, an oscillatory motion to achieve a selected radiation field whereby calculation of transmission measurements within a body positioned within the tomograph scanner is achieved. When not being circulated, the radiation source is held within a shield. Circulation of the transport fluid, typically a hydraulic fluid, is typically accomplished using a positive displacement pump. Position sensors are used to monitor the movement of the source in the conduit as well as its position within the shield. Disconnect units permit removal of the radiation source, as contained in the shield, from the system without accessing any other portions of the system. In another embodiment, the point source is a CT device.

摘要： PET system including array, data processing, and data acquisition. Data acquisition includes one-to-N channel write striping, N-to-one channel read unstriping, N data storage elements, and control logic. Control logic allocates (statically or dynamically) write/read access to data storage elements. Dynamic allocation can be conditional, e.g., that data storage elements be available to receive all input data from array. Embodiments include an input buffer where the condition is determined dynamically based on capacity of the input buffer to temporarily preserve all input data supplied during periods data storage element unavailability. Communication between array and data acquisition can be Fibre Channel simplex implementing only FC-0, FC-1. Data storage elements have data handling bandwidth equal to or greater than (data output rate /N) plus (data input rate/N). Control logic, write striping, read unstriping can be implemented in FPGA. Data storage elements can form a Redundant Array of Independent Disks, e.g., RAID 0.

摘要： A system identifies when received packets are lost at a node in a multi-node processing chain. The system processing chain may include a gantry interface module for receiving coincident event data from a PET (Positron Emission Tomography) detector array, a DMA (direct memory access) rebinner card, and a transmission line coupled between the gantry interface module and the DMA card. FPGA and FIFO elements in each processing portion receive packets that may be lost if there is insufficient FIFO capacity. Lost packets are marked, discarded, and counted. At specified intervals, set in accordance with a threshold number of packets received a lost tally data packet is generated that includes count information for lost packets. The lost tally data packet is forwarded downstream when sufficient storage capacity exists.

摘要： A method of making a composite blade that is attachable to a rotating shaft using a conventional metal blade attachment. A blade is formed from a composite material with a blade root at one end thereof. A metallic member having an external shape conforming to a conventional metal blade root is shaped with an interior cavity having an opening for receipt of the blade root. Before the composite material is fully cured, a bladder is formed into or is inserted into an end of the blade root and inflated, thereby forcing the composite material into intimate contact with the interior cavity of the metallic member, thereby ensuring a fret-free interface upon final curing of the composite material. The interior cavity of the metallic member may be shaped or surfaced to improve the load carrying capability there between.

摘要： A shared redundancy prefetch scheme to provide a reduced number of fuses. DDR SDRAMs allow burst addressing at various burst lengths. DDR SDRAMs generally implement LEFT and RIGHT segment column addressing. In DDR SDRAMs which implement redundant memory arrays, fuses may be used to provide access to the redundant columns. Because burst addressing may begin with a RIGHT segment address, two different columns may be accessed on the same clock cycle. By providing a compare scheme which implements separate compare logic for the lower bits of the LEFT and RIGHT segments and compares these bits to a common fuse set used for both the LEFT and RIGHT segments, the number of fuses in the redundant DDR SDRAM scheme can be reduced.
