  		Fig. 1A —Entrance surface dose profiles along z-axis of patient anatomy (as this is simulated in mathematic phantom used for Monte Carlo calculations of E in CT examinations) are depicted for CT-guided interventional procedures that exhibited largest peak absorbed dose. Graphs show doses delivered at biopsy (A), radiofrequency ablation (B), drainage (C), and nephrostomy (D).
