Electromagnetic Surgical Navigation: Technologies and Applications
While there are numerous advantages of electromagnetic components in interventional devices, it takes careful optimization of EM sensors within a device to achieve maximum performance. One-size-fits-all solutions rarely reflect the complexities of a particular clinical application, nor do they automatically provide optimal performance within modern interventional devices. This overview begins with a look at principles of electromagnetic navigation device operation and then takes a closer look at sensor optimization and key aspects of the design process related to permeability, magnetic saturation, and Johnson-Nyquist noise. The advantages of full-length device design for electromagnetic compatibility will also be considered.
