The VDARC node will take advantage of a standard, off-the-shelf motherboard, using dual microprocessors to increase processing density. The VDARC node will use very high performance general-purpose processors, memory, and a server motherboard with GB Ethernet and SCSI port(s), and power supply.

The chassis is a standard EIA 19" x 2U rack-mount with a maximum depth of 20". The chassis have a cooling system capable of sufficiently dissipating heat created by the motherboard's dual processors.

The VDARC will boot up when AC power is provided to the components power supply without requiring a PWON signal toggle. Such a hardware switch is needed for installation power-on and recovery from unexpected BIOS power-on settings.

A power-on LED will indicate that the VDARC power supply is providing DC output to the motherboard and should be mounted on the front of the chassis. Additional LED indicators such as on/off/blinking are more fully described in motherboard vendor specifications.

The VDARC shall be able to be reset by a single hardware switch located on the front of the chassis.

The VDARC disk consists of a single SCSI or E-IDE disk and provides OS code, application programs, tables, and parameters to the GOC5. All nodes in the GOC5 are booted from this disk, which also has the swap partition area to the VDARC node.

• Rotation speed: 7,200 rpm or higher

• Interface: ATA100/133 (recommended) or newer; Ultra160/320 SCSI (acceptable)

• Capacity: 36GB or higher

• Form Factor: 1" height, 3½” HDD

• Connection: 40-pin ATA100, 80-pin SCA2, or HD68-pin

The high-speed Scan Data Disks are connected to the VDARC node via an internal Ultra320 SCSI bus. To increase the disk read/write speeds software RAID0 (striping) is employed. The Scan Data Disk configuration may change according to the number of detector slices, DAS trigger rates, and/or IG performance.

• Rotation speed: 7.2k, 10k, or 15k rpm or higher

• Interface: Ultra320 SCSI or successor

• Capacity: 18, 36, 73, 146, or 300GB

• Form factor: 1" height x 3½” HDD

• Connection: HD68-pin, powered by 4-pin commercial Mate-N-Lok

• RAID0: striping up to Twelve (12) disks

This PCI VDIP card supports almost the same functionality as the current DIP in that it converts the optical signal received from the Gantry into electrical raw data and writes that data to one of the double buffers on the card. When the received data count reaches a predetermined value it will switch over to the other buffer. The VDARC then receives this data via the PCI bus.

• Serial data received from a fiber optic interface (see Table 1).

• For 32 slice configuration, use channel 1 for data transfer. Do not use channel 2.

• For 64 slice configuration, use channel 1 for transferring data from DAS A-side and channel 2 for transferring data from DAS B-side.

• Optical fiber channel 1 and channel 2 cannot be swapped. When channel 1 or channel 2 has the wrong data for the channel, the VDIP will generate a PCI interrupt and show “incorrect channel connection” at the interrupt status register.

Additional details can be found in the DRS spec. - 2382000DRS.

Each IG node is to be connected to the VDARC via an off-the-shelf Gigabit Ethernet (GbE) card connected to one of the VDARC's PCI-X slots. Depending on the number of optional IG nodes additional GbE cards may be added to the VDARC.

• Dual Gigabit Ethernet ports

• 10Base-T, 100Base-TX, 1000Base-TX IEEE802.3ab compatible

• 64bit, 66MHz (or higher) PCI-X interface

• Low profile form factor

The DVD-ROM drive is used for software installation, system diagnostics, and to support stand-alone operation of the VDARC.

The IG computer will be identical to the VDARC computer as described in above with the following exceptions:

• Chassis size: 19" rack-mount type EIA 1U height x 20" max depth

• DVD-ROM Drive: the IG computer will not have a DVD-ROM drive

This “low-profile” PCI card accelerates the two-dimensional (2D) back-projection process of the GOC5 and is plugged into a 64bit, 66MHz (533MB/sec) PCI-X slot on the IG node.

This VCT Recon Accelerator Card (VRAC) shall increase the reconstruction performance of the Global Operator Console Version 5 (GOC5) by off-loading 3-dimensional, or cone beam, back-projection (3D-BP) from its general-purpose processors to fully programmable hardware. The current software version of 3D-BP creates one image, or frame, every 3-seconds. This hardware implementation Has the capability to create images at a rate of 7-frames per second (FPS). The card is on the PCI-X bus of each IG Node. All communication between the node’s Host Computer and the VRAC is through this bus.

Following are the high-level requirements for the VRAC card:

• Perform 2D parallel beam back-projection at >6fps

• PCI-X low-profile compatible

• Communicate with IG computer through a go => complete protocol

• Support PCI and Mailbox interrupts

• Reconstruct any image matrix size up to 524,288 32bit pixels

• In-system programmable FPGA design via software download

The major elements of the VRAC card consist of:

• 4 Field Programmable Gate Array (FPGA)

• QDR™ SRAM - creates two blocks of memory

• FLASH Memory - contains the FPGA's configuration code
