Abstract:
:The Cameco lung counter has been recalibrated using the Lawrence Livermore National Laboratory torso phantom using an extended lung set (i.e., longer than the original set). The previous calibration had used the Japanese Atomic Energy Research Institute torso phantom. The new calibration had lower counting efficiencies and, as a result, higher minimum detectable activities. The recalibrated Cameco lung counter was used to measure an extended lung set that had the volume reduced by using modified planar inserts for the sliced lungs as the extended lung set has a lung volume that is larger than Reference Man. This work has shown that sliced lungs can be used to alter the characteristics of the phantom's lung inserts substantially and provide flexibility in measurements previously not recognized.
