    CHAPTER 9 ADVANCED OPERATIONS The following subsections provide information on advanced operations of microSTARii. This includes information about Linear/Non-Linear ranges, general calibration, creating simulated calibrations, and calculating and applying Sensitivity Adjustment factors. These procedures should only be completed by advanced users. The associated permissions must be assigned in order to complete these operational tasks.

  • Page 66: Measurement Calibration

    Calibrations are performed using one of the two types of calibration dosimeters (calsets): 1. LANDAUER-Manufactured LANDAUER ships a calset with the microSTARii that includes common dose ranges (80 kVp or 662 keV, or other non-standard energies depending on customer application). This set is primarily used for system performance monitoring.
  • Page 67 NOTE: All LANDAUER-manufactured calsets provide a baseline for 80 kVp, 662 keV, or other exposure conditions. A custom calset will mirror the conditions in your facility. To create a custom calset, irradiate screened nanoDots using the exposure conditions in your environment.

  • Page 68: Calibration Considerations

    To perform a new calibration, use the following procedure. The general procedure is the same for all calibrations (LANDAUER-manufactured calsets, custom calsets, Linear, and Non-Linear).

  • Page 70: Simulated Calibrations

    Simulated calibrations are pairs of strong and weak beam calibrations created based on existing calibrations that were created using the LANDAUER-provided NIST-traceable sets or customer- manufactured sets. Simulated calibrations can be created if you do not have a full calibration set with the desired exposure properties.

  • Page 71: Sensitivity Adjustment Factor Values

    CAUTION: The implementation of the SAF is a custom feature and is not recommended for routine medical dosimetry applications. LANDAUER precisely determines the sensitivity value in controlled conditions. If the SAF is implemented, the LANDAUER-determined sensitivity assignment is voided. NOTES: The SAF correction factor is only supported in Linear dose calculations.

  • Page 72: Test Conditions

    If you are experiencing an issue with the sensitivity of your nanoDots, contact LANDAUER for assistance (See section 12.1 for contact information). The Sensitivity Assessment tab features are used to assess the sensitivity for each nanoDot in a test population that has been exposed to a precisely known dose. The re-computed sensitivity is referred...
  • Page 73 If there is a significant difference in values and the interval of time between the calibration used to read the dosimeter, the test was very short, and the reader performance was stable, the difference may be a result of uncertainty in labeled sensitivity of the nanoDot. If the difference between these measurements is assessed for the whole population of nanoDots, symmetry in the distribution would be expected.
