Assessment of Bidirectional Compatibility between a Novel Magnetic Tracking System and C-Arm Fluoroscopy

Fluoroscopy is an X-ray-based medical imaging technique that is commonly used for guiding surgical interventions. The 2D projective nature of this modality is inherently associated with the loss of depth projection, making accurate placements of surgical instrumentation challenging. The integration of image-guided surgical navigation systems into fluoroscopy-guided interventions has been shown to increase procedural accuracy. Attempts to incorporate magnetic tracking systems into fluoroscopy-guided interventions have been met with two main limitations: its tracking accuracy is affected by the presence of the C-arm, and the required placement of the magnetic field generator can block the X-ray beam and generate image artifacts. A novel radiolucent magnetic field generator prototype, with “metal immunity mode” has recently been developed and the objectives of this thesis are to evaluate the magnetic tracking accuracy in the C-arm suite, and the impact of the radiolucent field generator prototype on fluoroscopic image quality.
