Figure 4. Analysis of Image Noise.

Figure 4

Image noise was measured using a 21 mm diameter syringe phantom as detailed in Materials and Methods.
  1. The relationship between standard deviation of image noise and detector pixel size as a function of reconstruction algorithm.
  2. The relationship between standard deviation of image noise and exposure time as a function of reconstruction algorithm.
  3. The relationship between standard deviation of image noise and reconstructed voxel size as a function of reconstruction algorithm.
  4. Reconstructed phantom images obtained using 10 µm (top) or 50 µm (bottom) reconstruction voxels, as a function of reconstruction algorithm.
