Aurora Tools and Sensors, and Accessories

NDI offers a wide selection of both individual sensor coils and tools for use with the Aurora System.

Aurora Sensors

NDI manufactures the smallest, most cost-efficient electromagnetic tracking sensors on the market today. These sensors have been designed for integration into third-party instruments and offer the following features:

Cost-efficient sensors, allowing for disposable applications
Robust sensor designs for daily re-use applications
Sensors as small as 0.3 mm in diameter for integration into high-gauge needles

Five Degree-of-Freedom Sensors

These five degree-of-freedom (DOF) sensors are small, allowing for many integration options. The x-y-z position of the sensor and two of its orientations are reported, allowing surgical instruments to be displayed in the correct anatomical context in real-time.

Aurora 5DOF Sensor 0.5 mm x 8 mm	This sensor integrates into rigid or flexible tools where a small diameter is necessary. The sensor and lead wires are surrounded by a protective material, which facilitates integration (for example, into needles). Part Number: 610099 Sensor Dimensions: 0.5 mm diameter x 8 mm length
Aurora 5DOF Sensor 0.8 mm x 11 mm	This sensor is mounted to a tiny PCB, which makes it more robust than our standard 5DOF sensor. This sensor is manufactured using mass-market technologies that provide the enhanced robustness of PCB design. Part Number: 610090 Sensor Dimensions: 0.8 mm diameter x 11 mm length
Aurora Shielded and Isolated 5DOF Sensor 0.9 x 12 mm	The sensor is encased in a protective tube; the lead wires are shielded to reduce interference from external electrical fields; and the entire assembly is electrically isolated. The design offers more mechanical robustness than other sensors, and can withstand more than 500 bending cycles (at a bending radius of 7.5 mm and ±180° bending angle). Part Number: 610057 Sensor Dimensions: 0.9 mm diameter x 12 mm length
Aurora Encapsulated 5DOF Sensor 0.9 x 6 mm	This shorter sensor supports integration into tools that require tighter bending performance. Its accuracy is slightly less than the longer 5DOF sensors. The sensor is encased in a protective tube and the assembly will withstand more than 100 bending cycles (at a bending radius of 7.5 mm and ±180° bending angle). Part Number: 610058 Sensor Dimensions: 0.9 mm diameter x 6 mm length

Six Degree-of-Freedom Sensors

For applications that require tracking all six degrees of freedom (6DOF).

Aurora Mini 6DOF Sensor 1.8 mm x 9 mm	This general purpose 6DOF sensor is ideal for applications that required tracking of all six degrees of freedom. This sensor is encased in a protective tube whose small diameter and short length allow for many integration possibilities. Part Number: 610029 Sensor Dimensions: 1.8 mm diameter x 9 mm length
Aurora Micro 6DOF Sensor 0.8 mm x 9 mm	This is the smallest 6DOF sensor offered by NDI. This sensor is supplied pre-soldered to a REDEL connector containing a pre-programmed SROM device, allowing the sensor to be used out of the box. The sensor is encased in a protective tube and connected to a flexible micro-cable that can withstand more than 10,000 bending cycles (at a bending radius of 7.5 mm and ±180° bending angle). Part Number: 610059 Sensor Dimensions: 0.8 mm diameter x 9 mm length

Ready-To-Use Tools

Ready-to-use tools reduce integration efforts and enable rapid application development. These tools incorporate everything required to begin tracking right out-of-the-box, (including the sensor, cabling, enclosure, connection, and firmware components).

Aurora Multi-Purpose Tools

The following multi-purpose tools provide the basic functions common in many tracking and computer-assisted applications.

Aurora 6DOF Probe, Straight Tip, Standard	This is a general purpose digitizing probe with a rigid, straight metal tip. OEM customization of the metal tip length and shape is also possible when required for specific applications. Part Number: 610065 Dimensions: Tip – 65 mm long x 3 mm diameter
Aurora 6DOF Reference, 25 mm Disc, Standard	This is a general purpose tracking reference that allows for many fixation methods. The flat PEEK disc incorporates two reamed holes for fixation, and the upper side of the disc incorporates a mark that identifies the centre of an optional hole that can be drilled if required. The tool can also be secured with adhesive strips for temporary fixation. Part Number: 610066 Dimensions: 25 mm x 5 mm thick
Aurora 6DOF Cable Tool, 2.5 mm x 11 mm	This is a very robust, multi-purpose tool. The Cable Tool is designed for researcher or OEM customer evaluation and prototyping. This tool contains a 6DOF sensor at the tip of a flexible 2 m shielded cable. The cable has a silicone outer jacket that is robust and easy to handle. Part Number: 610016 Dimensions: 2.5 mm diameter x 2 m length (Sensor is 12 mm in length)

Application Specific Tools

The applications for EM tracking in the medical field continue to expand and the ability of the technology to enhance procedures which involve minimally-invasive instrumentation is gaining recognition. EM tracking can give users more precision, greater spatial awareness, and higher confidence during interventional procedures. NDI has the experience and resources required to customize these tools to meet specific OEM requirements.
