CT dose modulation using automatic exposure control in whole-body PET/CT: effects of scout imaging direction and arm positioning
Automatic exposure control (AEC) modulates tube current and consequently X-ray exposure in CT. We investigated the behavior of AEC systems in whole-body PET/CT. CT images of a whole-body phantom were acquired using AEC on two scanners from different manufactures. The effects of scout imaging directi...
