| titleOfInvention | Calibration bias reduction in pressurized gas ionization chamber based dose calibrators |
| abstract | For dose calibration in functional imaging, different precision sources of the same long-lived isotope are used for calibration, avoiding having to transport one source from one location to another. Find the ratio of the sensitivity of the gas ionization chamber-based dose calibrator at the reference laboratory to the precision source of long-lived isotopes to the source with the isotope to be used for imaging. A measure of the sensitivity of the local gas ionization chamber-based dose calibrator to another source with long-lived isotopes and the ratio from the remote gas ionization chamber-based dose calibrator to determine the local gas ionization chamber-based dose calibrator at the clinical site Sensitivity of dose calibrators for ionization chambers to radiopharmaceutical isotopes. The bias and corresponding dose of the radiopharmaceutical to be used to image the patient is based on the activity of the radiopharmaceutical being calibrated. |
