System Configuration (Optima Advance 18BW39.x)

Prerequisites

Overview

The following procedure describes and illustrates the System Configuration procedure commonly referred to as the “reconfig” script. It is important to follow the steps listed in the order presented.

On the following screens, you should make the changes necessary, pressing the corresponding tabs at the top of the screen to move from screen to screen. When you are done, you can either press the ACCEPT button to start the reconfiguration process, or press the QUIT button to exit without changing the system configuration.

While the reconfiguration is going on, messages are displayed in a Shell Window that closes when reconfiguration is complete. Should you later want to review the reconfiguration output, it is logged to the following file: /var/adm/install.log.YYYYMMDDWWWHHMMSS, where YYYYMMDDWWWHHMMSS is the Date/Time that the reconfiguration was started.

To view the file, type: more /var/adm/install.log.YYYYMMDDWWWHHMMSS

note: There is NO safe way to abort the reconfiguration after pressing the ACCEPT button. If the entries made in the screens were incorrect, DO NOT try to stop the reconfiguration. Instead, wait for it to complete and rerun “reconfig” entering the correct parameters.

Procedure

  1. Shut down Applications from the Common Service Desktop, Utilities Tab.
  2. Open a Terminal Window, and log on as root:
    1. Type: {ctuser@hostname} su –ENTER
    2. Type the root password and press ENTER
  3. Launch the Configuration utility:

    Type: [root@hostname] reconfig ENTER

  4. The CT Software Install Utility Window will appear.

    Figure 1. CT Software Install Utility Window

    note: The following shows the screens that are used to change the configuration of the system. These screens are the same as those used for the Software Configuration during Load From Cold. The actual screens will vary depending on the current configuration of your system.
  5. Click CONFIG.
    note:

    The following configuration pages show the screens that are used to change the configuration of the system.

    These screens are the same as those used for the Software Configuration during Load From Cold.

    The actual screens will vary depending on the current configuration of your system.

    10. Dose Record – Configures support for DICOM Dose SR Record option for saving dose information with study. Default is “ON”. The dose information is saved in a DICOM structured report. The DICOM standard defines a new DICOM X-Ray Radiation SR SOP class, which the other systems must support. The Dose SR feature saves an exam's dose information in this format.

      • Select ON - Saves the dose information in a DICOM Enhanced SR SOP Class

      • Select OFF - Turns off option

      • Select FULL - Saves the dose information in a DICOM X-Ray Radiation Dose SR SOP Class

      note: This preference shall not be enabled unless specifically requested by the Customer and the Evaluation of Dose SR Compatibility procedure has been executed and indicates that the other hospital systems support the Dose Report SOP classes.
    11. Preferred KV - Configures the preferred kV that the Fast Cal Routine will calibrate (80, 100, 120, 140 in the Selected Preferred Fast Cal KV field). The default selections are 80, 100, 120, and 140.
    12. Target Noise Index Table - Be sure Table 2 is selected.
    13. Gantry Layout - Configures the preference for Patient loading. Choose correct orientation depending on site specific Gantry layout.
    14. Flip and Rotate - Configures the preference for allowing the Flip and Rotate feature to be turn on in the User Interface on the (Left) SCAN Monitor. This preference allows the Customer to apply custom orientation changes based on Exam Type and Reconstruction methods on DICOM images that will be transferred to PACS and related systems.
      note: This preference shall not be enabled unless specifically requested by the Customer and the Evaluation of Image Flip and Rotate Compatibility procedure has been executed and all DICOM test images pass orientation check.
    15. Emergency Patient Mode - Configures the preference for allowing the emergency patient to be turned on in the user interface.
    16. Auto Exam Description - Configures the auto exam.

    Figure 5. Network Configuration Window

    note: This screen provides the ability to declare the CT system on a hospital network. Key information such as Host Name, IP Address, Net Mask (for CT systems on a subnet) must be obtained from the hospital network administrator.
  12. Configure Network Settings.
    1. Enter the Suite Name. The Suite name must start with a letter, followed by three (3) alpha-numeric characters. Total must be four characters long. The name of the OC interface will be <Suite Name> _OC, within the scanner subnet. Typically, you should use su01 or ct01 (“su” and “ct” must be lowercase), unless the customer prefers a different suite name.
    2. Enter the hospital provided Station Name.

      • MUST NOT exceed 16 characters.

      • MUST only contain the following characters: a through z, A through Z and 0 through 9.

      The Station Name is typically stmary or ct01.

      note: If left blank, the Station Name defaults to the Host Name.
    3. Enter the hospital provided Host Name. The Host Name identifies the network hostname and AE Title of the CT system to the hospital’s network. The Host Name:

      • MUST NOT exceed 16 characters

      • MUST only contain the following characters: a through z, A through Z and 0 through 9.

      • MUST have at least one of the following characters: a through z or A through Z. (Host Name MUST be Alpha or Alpha-Numeric)

    4. Enter the hospital provided IP Address for the system
    5. Enter the hospital provided Net Mask Address for the system.
    6. Enter the hospital provided Broadcast Address for the system.
    7. Enter the hospital provided Default Gateway Address for the system.
    8. Enable TCP Segmentation Offload – Default YES. If network transfers to certain PACS systems are slow, this can be set to No and may increase the transfer speed.
    9. Enable AW DirectConnect if option provided with system. Reviewing the order information to see if option is included.
      note: Items j – l are visible only when Advanced Options is selected.
    10. Enter the hospital provided NIS Domain Name and IP Address for the system, if NIS is utilized on site.
    11. Enable Network Time Protocol, if so instructed by hospital. Hospital must have an NTP Server available and the scanner should be synchronized with the Hospital’s time.
    12. Enable Change DARC Subnet, if so instructed by hospital.
      note: Only enable this feature if there is an IP conflict between the system local network and the hospital local network. The console utilizes a DHCP Server to configure the Console local network address for communications between Host, Gantry/Table and Reconstruction Engine Computers. Default local addresses in the console use the following local Octets: 172.16.xxx.xxx. And this function changes the address to 169.254.0.xxx.
  13. Review all screens to be sure the information entered is correct before proceeding to the next step.
  14. Click ACCEPT to accept the changes made. (See Figure 6.)

    Figure 6. Accept Configuration Window

    After clicking ACCEPT the system configures the system. While the configuration is going on, the results are displayed in a Shell window that closes when the loading process is complete. (See Figure 7.)

    Figure 7. Shell Configuration Window

  15. When the configuration changes are complete, the system displays a prompt to reboot.
  16. Click YES. (See Figure 8.)

    Figure 8. Configuration Complete Window

  17. The system will automatically log in as ctuser after the reboot. Select [OK] on the Autostart Disabled popup message.
  18. Open a Terminal Window. Type: {ctuser@hostname} stENTER
  19. Remember, if necessary perform System State Save Restore whenever the “reconfig” script is executed.
