Comparison of the Scanning Linear Estimator (SLE) and ROI Methods for Quantitative SPECT Imaging

In quantitative emission tomography, tumor activity is typically estimated from calculations on a region of interest (ROI) identified in the reconstructed slices. In these calculations, unpredictable bias arising from the null functions of the imaging system affects ROI estimates. The magnitude of t...
