Abstract :
Proposes an algorithm based on simulated annealing for automatic seed matching and reconstruction using either 3 radiographic films or 3 fluoroscopic images. An algorithm for automated seed identification on fluoroscopic images is also proposed. The authors present results obtained for 112 clinical cases, 100 simulated cases and one phantom reconstruction with known seed locations. Results for clinical eases are compared with results obtained using the 3-film technique
