Dependence on Reconstruction Parameters

• Reconstruction filter

  • Convolution kernel limits resolution. Resolution must be balanced with noise

• Pixel size

  • Can be limiting factor in resolution - can’t resolve details smaller than 1 pixel
    • Limited by reconstruction field of view
    • Limited by reconstruction matrix

• e.g. 512x512 matrix, 30cm RFOV. Pixel size is 0.6mm - limiting resolution to 8.3lp/cm
