A Computer-Aided Analysis Method of SPECT Brain Images for Quantitative Treatment Monitoring: Performance Evaluations and Clinical Applications

Figure 3

Comparisons of detected recovered regions with the ground truth for three-size lesions (8 mm: diameter of 8 mm, 16 mm: diameter of 16 mm, and 24 mm: diameter of 24 mm) at nine different change-rates (10% to 90%). (a) The Dice similarity coefficient (DSC) for measuring the accuracy of the recovered regions detection comparing with the ground truth; (b) linear regressions of estimated change-rates (CR) of the recovered regions with the real values.
