  • Page 8: Hardware Overview

    Hardware Overview The Accu-Gold system consists of a digitizer module, sensor(s) and a display. The Accu-Gold digitizer is available in different models that are suited for specific applications, the differences being which sensors can be used. The Accu-Gold software is the same for all models but the measurement data that is available will depend on the model digitizer used and connected sensor(s).

  • Page 9: What Is Accu-Gold2

    What is Accu-Gold2? Radcal’s Accu-Gold software has been redesigned from the ground up with a modernized user interface and under-the-hood capabilities that will ensure continuing compatibility with Microsoft products (e.g. Windows & Office) as well as expanded capabilities for the Accu-Gold family of measurement systems.

  • Page 10: Starting Accu-Gold

    Starting Accu-Gold When launched, the Accu-Gold2 brings up a screen that lets you choose the appropriate connection method to the Accu-Gold digitizer. Connect via Wi-Fi – The Accu-Gold Nugget lets you connect to the digitizer wirelessly. Connect via USB - When the USB cable is the connection method to the digitizer.

  • Page 11: Starting Accu-Gold Via Wi-Fi

    For the Accu-Gold Touch, start the Touch in WiFi mode and wait for the blue light to flash rapidly. Start Accu-Gold2 and choose Connect via Wi-Fi: The software will look for “Nugget…” (or “Touch”) on the wireless networks list, and establish a connection to it sending it the password it requires.

  • Page 17: Agms Pre-Pulse Mode

    The “AGMS Pre-Pulse Mode” algorithm is designed to accommodate the initial pre-heat kV pulses commonly found with some dental generators such as the Gendex 770. Pre-Pulse ON should not be selected for other pulsed waveforms such as pulsed fluoroscopy or tomography. Note: The dose remains integrated over the entire exposure regardless of the setting (On or Off), only the kV and time calculations are affected.

  • Page 18: Setting Up The Hardware

    Setting up the Hardware To set up the Accu-Gold hardware 1. Connect the sensor(s) to the digitizer. Connect the USB cable to the digitizer and then the computer. 2. Position the sensor to make a measurement. Note: Position the sensor before clicking the Connect button; moving the sensor or cable after clicking the Connect button may trigger a false measurement.

    The maximum duration in this mode is 2.45 days. Note that sessions containing many long exposures with waveform data may take significant time to save or load data. Modern computers with fast disc storage and processors will have better performance in this situation. Contact Sales for Radcal’s current tablet display options.

  • Page 26: Measurement Limitations

    Measurement Limitations The Radcal AGMS Series of Multi-Sensors are highly capable instruments that will generally provide a comprehensive set of measurements throughout a wide range of diagnostic x-ray applications. However, there are some conditions under which the sensor will provide a more restricted set of measurements. These conditions...

  • Page 27: Selecting A Display Profile

    When making background or scatter measurements, the readings may be too low to trigger a measurement. In that case a second sensor placed in the beam can be used to trigger the measurement which will guarantee that the ion chamber’s signal is captured during the triggering period of that sensor. A 180cc, 500cc or 1800cc chamber may be used, depending on the radiation levels to be detected.

  • Page 28: Automatic Profile

    Automatic Profile In Measurement view, profiles define which values are displayed in the matrix. You will rarely want to choose a different profile other than Automatic Profile (Auto). Automatic Profile looks at the sensors in a measurement and whether it is diagnostic, fluoro or mammo and adjusts the matrix dynamically.
  • Page 29 Use the table preview popup to select the desired matrix layout. In the example above, the matrix changed from a 2x3 layout to a 3x3 layout. By changing to Custom Profile, the labels of the matrix fields become clickable. After clicking on the label, a drop-down menu appears for selecting a different result value.
  • Page 30 Each cell allows you to pick from the list of possible outputs from the digitizer and sensors. See Appendix E for a complete list. To create multiple custom profiles, click on the pencil in the lower right corner. The ‘Custom Profile’ becomes changeable.

  • Page 37: Region Of Interest" (Roi)

    Note: For short exposures (<1 s), filters should be applied with care so as not to smooth important detail. Because the filter is non-destructive, different values may be easily tried. Application of a filter will not affect any of the measurement values (e.g. dose, kV, time). When a session is saved with filters applied, Accu-Gold will retain the filtered waveform selection when the file is re-opened.
  • Page 38  Clicking on the magnifying glass in the ROI window will automatically expand the ROI to fill the Wave screen.  The copy results to clipboard and the Extract to new measurement from Region of Interest will be explained later in this document. As another example, assessment of performance should probably occur near the end of the exposure after the mA has stabilized.

    If the data contained in the ROI window does not provide all of the details needed for evaluation, clicking on the icon in the ROI window will put all of the details on the clipboard. A simple “Paste” command (CTRL-V), will put the text data in Excel or a text document. For the Example above: When a region of interest has been selected, it is possible to non-destructively extract an ROI selection and preserve it as a daughter of the original parent.

    Special grounding accessories partially mitigated this effect, but were often inconvenient. Radcal is excited to announce that research and development efforts have yielded a new ion chamber technology, the “Quiet Bias”. A specially designed electronic circuit filters the bias voltage supply eliminating noise that would have appeared in the output signal.
