  • Page 12 Due to the magnet top off you may have to sting the magnet and handle dewars during this fill. The gas cylinders must be strapped down and when not in use have their cap on, also be very careful of the dewars. In most cases, Air Products or a cryogen contractor will take care of this task, but you should be aware of this in case you need to perform it.
  • Page 13 LOTO Service Documentation is Accessible via the Service Methods Website by clicking on “Safety” and then the correct procedure name under “Lock Out Tag Out”. Note that for SV, all LOTO procedures involving LOTO of the SYSTEMS CABINET require shut down of the Simple OC first. This is because powering down the Simple OC ensures correct soft power down of the Image Compute Node.

A leak sensor is installed in front of XFD to detect leakage of water pipe connectors. XFD slew rate is 100, which is twice as much as HFD-lite used in HDe system.
  • Page 36 In order to improve gradient system service capability, traditional cables and connectors are not used for connection between XFAs and XFD-PS in SV system. XFD-PS power output and XFA power input are used plugs and sockets, which is connected by a newly designed component, Power panel.
  • Page 37 Power panel connects XFAs and XFD-PS. It can be accessed by removing its cover in the magnet room. If the power panel needs to be replaced, be assure to wait for at least 15 minutes after XFD power-off. And the nethermost plug must be removed before removing other plugs.

SerialLite is a serial protocol developed by Altera Corp. and Innocor Ltd. Altera provides an IP core implementation of SerialLite that utilizes the high-speed serial transceivers in their Stratix GX FPGAs.
  • Page 95 This block diagram shows RF receive chain in SV system. If the system configuration is MR360 without Express coil, J22 in Mega Switch has no cable connection. Mega Switch selects different input signal from Port A coil, PA coil and body coil, and amplifies the selected signal, and converts them to intermediate frequency signal, which center frequency is about 16MHz.
  • Page 98 During RF transmitting, Unblank signal will be generated and sent to synchronize remote devices. Digital Unblank signal is sent from CAM lite to Exciter via DVMR link. The analog Unblank signal is generated by the Exciter. Then, the analog Unblank signal is sent to Driver module lite Unblank distributor, which outputs same Unblank signals and sends to UPM1, UPM2, RF amplifier interface board and SRFD3.
  • Page 99 PCIAA is functionally similar to GOCAA (Global Operator Console Audio Assembly), but is only used for audio communication between operator and patient. It locates in the host PC and is mounted on one PCI socket. But PCIAA has no any electrical connection with PCI socket, only occupies one PCI slot to fix.
  • Page 100 Simple OC consists of host PC and chassis. Host, LCD and Ethernet switch get the power supply from the power strip in the chassis. There is a circuit breaker on the power strip, which can only be accessed after right cover removal. Pay attention to the service key after inserted in the front USB port.

  • Page 110 MPS (Magnet Power Supply) is for ramping up power supply. It will have no output after E-stop contactor is tripped.
  • Page 111 There are five Switching AC to DC power supplies located on the upper right of the system cabinet. DCPS for DM_Lite, Exciter, Mega SW & RRX only have input power 120VAC, no control signal, which means that the three DCPS have stable and uncontrolled output once the input power 120VAC is engaged.
  • Page 113 1.Overview The PHPS stands for Patient Handling Power Supply. It functionally replaces the SSM (System Support Module). There are three types of PHPS for different type of MR.

  • Page 121 The IRF3 is the third generation Interface and Remote RF Functions circuit board. It is designed for use within the DVMR system and, despite many architectural similarities, maintains no backwards compatibility with IRF or IRF2. The IRF3 primarily serves as a communications hub within the CAM chassis, supporting communication with one or two Remote Receiver devices (RRx), one or two Remote Exciter devices (DTx), and the XGD gradient subsystem via five identical high-speed (2Gbit) serial fiber optic interfaces implementing the DVMR Common Communications Link.
  • Page 122 The RF Amplifier Support Chassis (ASC) will house two complete Universal Power Monitors for redundancy.

It does the image processing and reconstruction functions that were previously done by the Reflex AP's in the Excite2A and Excite HD systems. The VRE in the SV system has only one ICN (Image Compute Node).
  • Page 127 VRF board contains an optical interface to receive scan data from Remote Receiver (RRx) board, filters the data and DMAs the data to the ICN for image reconstruction. The VRF board is physically installed in PCIs slot on the ICN. The VRF will receive an 80MHz reference clock from the exciter board.
  • Page 128 The SRFD3 RF Amplifier and Interface (SRFD3 Module) is the third phase in the development of the Scaleable RF Driver (SRFD) subsystem. It is the first liquid cooled amplifier and lower output power(10kW). The SRFD3 Module performs the following functions: Head/Body mode switching, CAN communication link decoding, control and status communication between the system and the RF amplifier, RF power amplification, and RF power sampling for power monitoring by the Universal Power Monitor (UPM).
  • Page 130 SRFD3 has been pre-adjusted in factory. You don’t need to adjust RF power on site during installation. Because the card 72 in the RF Power Measurement Kit is for 16KW power output, it is necessary to modify the measurement method.

For these items the system will rely on the user to check off the items as they are complete and click [Submit]. For all calibrations that have machine data, the tool can be launched the same way it was launched in previous versions of MR software –...
  • Page 177 How to read this matrix: The same tasks calibrations are listed along the top and along the side. The ideal order of task / calibration completion is from the top to the bottom. Anything with no red squares to the right has no pre-dependencies, therefore it can be run at any time. If there are red squares to the right of any of the tasks/calibrations, then the tasks/calibrations indicated in the vertical column(s) associated with each red square must be completed successfully before that task/calibration becomes available.
  • Page 178 Every time the user clicks on the “Calibration” tab of the CSD, as long as there is a service key plugged in, the ICW will be the only link available. Once all steps in Install Mode have been successfully completed, Maintenance Mode becomes available. In Maintenance Mode, any time you click on a calibration it will alert you to the possibility of pre- and post- dependencies.
  • Page 179 This matrix is the basis for the logic of the ICW in Maintenance Mode. If you click [More] on the pop-up from the previous slide, this is the matrix that you will see. It is good to become familiar with how to read this matrix so that when you perform re-calibrations at sites you will understand what it means.

  • Page 183 This new style 6-channel Grafidy fixture couldn’t be easier to use! It is simply a “plug and go” tool, meaning that when it is taken out of the box all that is required is that the user attaches the adaptor cable to the fixture and plugs it into the LPCA A-Port connector, unfolds the wings of the fixture, landmarks and begins the Grafidy calibration.
  • Page 184 Along with the new 6-channel Grafidy fixture defined in the previous slide, improvements have been made to the Grafidy calibration’s data acquisition and software. The tool first verifies proper fixture placement and signal from all channels. It then acquires data simultaneously from all channels, thus reducing calibration time.

  • Page 191 The Multicoil Receive Chain Tool provides a means of diagnosing problems in Multicoil Receive (MCR) chain hardware, without use of coils. The tool sends signals down the individual paths to isolate specific channels in the receive chain. The tool’s Graphical User Interface (GUI) guides the user through the various steps involved in running the tool and troubleshooting the problem.
