Use of an Electromagnetic Navigation System on a Phantom as a Training Simulator for CT-Guided Procedures

Electromagnetic navigation-assisted percutaneous endoscopic foraminoplasty and discectomy for lumbar disc herniation: technical note and preliminary results

“…The electromagnetic navigation system generates a magnetic field, which is used to transmit and receive electromagnetic signals to determine the spatial position of the target. The basic principle is to use the magnetic field of known spatial distribution to realize the positioning of objects in the magnetic field according to the data obtained by the sensor (23,24). Through the intraoperative real-time positioning system, the position of the surgical instrument in the field is accurately positioned.…”

“…Through the intraoperative real-time positioning system, the position of the surgical instrument in the field is accurately positioned. The operator can observe the actual position of the instruments by referring to the horizontal, coronal, and sagittal three-dimensional images displayed on the computer monitor (7,8,(21)(22)(23). Using electromagnetic navigation in percutaneous full-endoscopic surgery, surgeons can observe the farthest safe position that surgical tools can reach at real time, and maximally remove the lesion for a thorough decompression effect.…”

Computed Tomography-Navigation™ Electromagnetic System Compared to Conventional Computed Tomography Guidance for Percutaneous Lung Biopsy: A Single-Center Experience

“…Additionally, the system enables us to explore many different trajectories in the 3D volume, allowing the radiologist to choose the best option, that may lengthen the preparation time. Although a previous study showed that using the electromagnetic guidance minimized the impact of operator experience [ 15 ], allowing unskilled operators to obtain as good results as the best trained interventional radiologists, the system can still slow down the procedure for the most trained operators and for simple procedures [ 1 ].…”

“…In order to improve accuracy and limit X-ray exposure, a series of navigational guidance tools have been developed, based on the principle of “augmented reality” [ 1 , 9 ]. These new systems allow electromagnetic [ 2 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], or optical tracking of devices [ 19 , 20 , 21 , 22 , 23 ], that are used for interventional radiology or surgical procedures. Data from a previous patient’s scan can be used in a model to perform virtual real time navigation.…”
