How can patient dose be kept down during imaging?

Explanation:
Reducing the number of pictures lowers the total radiation dose because every image contributes some exposure, and the doses add up across all images. If you take more pictures, the patient receives more radiation; if you use higher dose CT protocols, the exposure per scan increases; and extending the exam duration typically means longer exposure time or more frames, raising the dose. So choosing to acquire only the essential images minimizes the overall dose while still preserving diagnostic value.
