(Left) Original (generation 0) AM PET design. (Right) AM PET original bungee cord support frame. (Reprinted with permission of (6).)
- FIGURE 2.
Generation 0 images. (Top left) A 2-mm-thick slice of brain after 1-min acquisition during head movement. A 333- to 444-MBq (9–12 mCi) dose of 18F-FDG was injected, and imaging took place after 2 half-lives had passed (74–111 MBq, or 2–3 mCi). Uptake is shown in frontal lobes and occipital cortex. Head of caudate can also be clearly identified. (Bottom left) Separate 2-mm slices were overlaid onto PET scan. This image was taken over 10 min. (Right) Concept of mobile imaging, using backpack to store electronics and support system for helmet. (Reprinted with permission of (6).)
