System Configuration

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.

    9. Dose Record: Configures support for DICOM Dose SR Record option for saving dose information with study. Default is “OFF”. 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.
    10. Preferred Fast Cal 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.
    11. Target Noise Index Table: Be sure Table 2 is selected.
    12. Gantry Layout: Configures the preference for Patient loading. Choose correct orientation depending on site specific Gantry layout.
    13. 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.
    14. Emergency Patient Mode: Select ON if customer prefers this feature.
    15. Auto Exam Description: Configures the auto exam.
    16. DMPR Reference Image: FE can turn on/off Reference Image generation for DMPR PACS transfer.
