Pet ct - Study guides, Class notes & Summaries

Well counter calibration - *quarterly* -A conversion process performed that allows the system to accurately interpret counts/pixel as activity/voxel. -Uses a known amount of radioactivity in a known volume of water in a phantom -Measure activity in dose calibrator & divide mean measured activity by mean calculated activity Why is homogeneity in the water phantom important? - -to have a uniform amount of the radionuclide, otherwise there'll be errors in the well counter calibration Me...
