Final answer:
Increased personnel dose is possible during CT scans, fluoroscopy, and mobile imaging, as these procedures involve the use of ionizing radiation which can lead to higher cumulative doses.
Step-by-step explanation:
Personnel dose could potentially be increased during CT scans, fluoroscopy, and mobile imaging because these modalities involve the use of ionizing radiation. CT scans use a series of X-ray measurements from different angles to create cross-sectional views (virtual slices) of the body, which can result in relatively high radiation doses due to the multiple images taken for detailed slices. Fluoroscopy involves the continuous emission of X-rays to create real-time images, leading to potentially high cumulative doses. Lastly, mobile imaging, often implying X-ray imaging performed outside of controlled radiology suites, can also present scenarios with higher personnel doses, especially if radiation safety practices are not strictly adhered to.
