Radiofrequency ablation is an interventional technique that in recent years has come to be
employed in very different medical fields, such as the elimination of cardiac arrhythmias or …

Although epidural analgesia is widely used for pain relief, it is associated with a significant
failure rate. Loss of resistance technique, tactile feedback from the needle, and surface …

When choosing an electromagnetic tracking system (EMTS) for image‐guided procedures
several factors must be taken into consideration. Among others these include the system's …

PURPOSE: To evaluate the spatial accuracy of electromagnetic needle tracking and
demonstrate the feasibility of ultrasonography (US)–computed tomography (CT) fusion …

Background Clinical use of image‐guided needle placement robots has lagged behind
laboratory‐demonstrated robotic capability. Bridging this gap requires reliable and easy‐to …

Electromagnetic tracking has great potential for assisting physicians in precision placement
of instruments during minimally invasive interventions in the abdomen, since …

Computed tomography (CT)‐guided percutaneous radiofrequency ablation (RFA) has
become a commonly used procedure in the treatment of liver tumors. One of the main …

Purpose: Two of the main challenges associated with electromagnetic (EM) tracking in
computer‐assisted interventions (CAIs) are (1) the compensation of systematic distance …

Diagnostic and therapeutic CT‐guided percutaneous interventions are clinical routine in
interventional radiology. Image‐guided navigation systems visualize the internal anatomy …
