Based on electromagnetic technology, the Aurora EM Tracking System is a world-class spatial measurement

product designed specifically for medical applications. The system provides real-time, sub-millimetric position and

orientation of miniaturized sensors that may be located inside or outside the body (no line-of-sight required). The sensors

are designed for integration into surgical tools and instruments such as needles, catheters, probes and scopes. Due to the small

size and varied designs, the sensors have broad applications from use in low-cost disposable products such as needles to robust,

daily use in reusable instruments such as endoscopes.

The ability to place the sensor at the tip of an instrument allows for the localization of flexible instruments within the body, opening up a host of new

medical applications previously not possible.

Only 3.4 cm thick, this FG is designed to be placed between the patient and the table.

The FG incorporates a thin barrier that minimizes any tracking distortions caused by

conductive or ferromagnetic materials located below it.

S E N S O R S

Small currents are induced in the sensors by the varying electromagnetic field

produced by the Field Generator. The characteristics of these electrical signals are

dependent on the distance and angle between a sensor and the Field Generator

S E N S O R I N T E R F A C E U N I T S ( S I U s )

Amplify and digitize the electrical signals from the sensors and provide an increased

distance between the System Control Unit and sensors, while minimizing the

potential for data noise.

sensor and interfaces with the host computer.

M E T A L I M M U N I T Y

All electromagnetic tracking systems use a magnetic field to determine the location of sensors in space. Outside influences on that magnetic field, for example eddy currents in nearby conductive materials, may lead to position errors of the sensors.

The effects of external influences cannot be completely counteracted, but the Aurora system software and hardware is specifically designed and integrated to reduce the effects to a minimum. Aurora is unaffected by most medical-grade stainless steel (300

series) and titanium. A Tabletop FG is also available which minimizes any distortions produced by patient tables or other materials below it.

NDI recognizes that OEMs wishing to incorporate electromagnetic tracking in their applications are generally

interested in customizing the Aurora components. This allows for the creation of new form-factors and

seamless integration into existing workflow.

ӹ Customized FGs become part of the solution rather than hardware to work around.

ӹ Customized electronic components allow for various form-factor solutions

• SIUs can be combined into a single break-out box

• SCU and SIUs can be combined into a single enclosure

• Simultaneous tracking of up to 16 sensor coils

ӹ Customized sensors and tools
