Figure 2: Illustrative case of frameless free-hand navigation-guided biopsy with electromagnetic navigation system. (a) The contrast-enhanced magnetic resonance imaging. (b) The setup scene for electromagnetic navigation system. (c) The endoscope arm is connected to the operation table and the biopsy needle is clamped to the holding arm through a piece of 14 Fr nelaton catheter. The electromagnetic flexible stylet is inserted into the inside of the inner lumen of the biopsy needle. (d) Navigation display during puncture. (e) The distant view of frameless free-hand navigation-guided biopsy during puncture
