Workflow for Determination of the Calibration Factor

The main steps to calculate the calibration factor within the Calibration Factor interface are:

  1. Load the calibration data.
  2. Verify that the start time is correct.
  3. Enter the activity measured within the VOI outlined on the corrected and calibrated PET phantom image ([kBq/cc]).
  4. Activate the Manual Offset radio button and enter the background activity value (generally 100 counts/sec).
  5. Enable the decay correction and select the radio isotope used in the calibration experiment.
  6. Set the calibration factor to the correction page activating the Set Factor button. Alternatively, save and set the calibration factor activating the Save Calibration Parameters button.

The experimental setup and the determination of the calibration factor are summarized in the workflow below:
