Patent number: 8314380Abstract: A patient bed drive mechanism, under control of a processor, is capable of continuously moving a patient bed through the a TOF-PET detector array having a stationary field of view (FOV) for a distance in excess of the physical extent of an axis of the array FOV. A direct memory access (DMA) rebinner card is coupled to the detector array to receive therefrom a stream of TOF-PET coincidence event data during the extent of movement of the bed. Image projection data are generated in real time from the acquired stream of TOF-PET coincidence event data via the DMA card.Type: GrantFiled: September 11, 2009Date of Patent: November 20, 2012Assignee: Siemens Medical Solutions USA, Inc.Inventors: John E. Breeding, William F. Jones, Wing K. Luk, Andrew P. Moor, Johnny H. Reed, David Townsend

Patent number: 8170855Abstract: A system for simulating a Positron Emission Tomography (PET) gantry has a computer system having a bus system for receiving expansion cards, a mass data storage support system, the mass storage system being operable to store coincidence-event and tag packet data, and a data transfer simulation card for said bus system, wherein the data transfer simulation card is operable to simulate transfer timing of the stored coincidence-event and tag packet data.Type: GrantFiled: April 28, 2008Date of Patent: May 1, 2012Assignee: Siemens Medical Solutions USA, Inc.Inventors: William Jones, John E. Breeding, Johnny H. Reed, Jimmy Everman, Michael E. Casey

Patent number: 8060696Abstract: 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.Type: GrantFiled: May 8, 2009Date of Patent: November 15, 2011Assignee: Siemens Medical Solutions USA, Inc.Inventors: William F.

Patent number: 7983186Abstract: 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.Type: GrantFiled: September 11, 2009Date of Patent: July 19, 2011Assignee: Siemens Medical Solutions USA, Inc.Inventors: John E. Breeding, Michael E. Casey, Jimmy Everman, William F. Jones, Wing K. Luk, Johnny H. Reed

Patent number: 6915004Abstract: Apparatus and methods for three dimensional image reconstruction from data acquired in a positron emission tomograph (PET). This invention uses a parallel/pipelined architecture for processing the acquired data as it is acquired from the scanner. The asynchronously acquired data is synchronously stepped through the stages performing histogramming, normalization, transmission/attenuation, Mu image reconstruction, attenuation correction, rebinning, image reconstruction, scatter correction, and image display.Type: GrantFiled: February 28, 2002Date of Patent: July 5, 2005Assignee: CTI PET Systems, Inc.Inventors: Danny F. Newport, Michael E. Casey, Wing K. Luk, Johnny H. Reed
