Article Figures & Data

Figures

  • FIGURE 1. 
    FIGURE 1. 

    Slice concentrations (Bq/mL) extracted from reconstructed images of data acquired with mobile PET/CT scanner on 2-bed-frame cylindric phantom at 4 random community hospitals. Slice concentrations from 4 locations demonstrated similar pattern, with center slices of scanner exhibiting better homogeneity.

  • FIGURE 2. 
    FIGURE 2. 

    Average sensitivity errors of Reveal RT Mobile PET/CT scanner, obtained over 19 consecutive mo, on day 1 and day 2, at our community health care center. Minor improvement is noticeable in average sensitivity of scanner on day 2.

  • FIGURE 3. 
    FIGURE 3. 

    Increase in internal temperature resulted in significant and nonuniform decrease in slice sensitivity of scanner.

  • FIGURE 4. 
    FIGURE 4. 

    Normalization improved sensitivity of mobile PET/CT scanner significantly, particularly at edges of field of view. norm = normalization.
