Much like vehicle GPS navigation, coordinate data are used to show where an object is in 3D space, and where it needs to go next. With vehicle GPS navigation, the car is moving and the destination is fixed. A map supplies the travel route. However, only a 2D (planar) view of the vehicle\u2019s position is available, and only movement along the longitude and latitude lines (X and Y axes, respectively) is shown. Altitude info (Z-axis) is missing, as is rotational data \u2013 only two degrees-of-freedom are reported. A view that limited cannot support complex OEM surgical navigation applications<\/span><\/p>

The <\/span>Polaris<\/a>\u00ae optical measurement solution, and <\/span>Aurora<\/a>\u00ae and <\/span>3D Guidance<\/a>\u00ae electromagnetic (EM) tracking solutions capture the position (X-Y-Z coordinate data) and orientation (roll, pitch, yaw) of an optical navigation marker or EM sensor in relation to a fixed object or reference point in 3D space.<\/span><\/p>

Position and orientation measurements also refer to the \u201cdegrees of freedom<\/a>\u201d (DOF) in which an object moves in 3D space. There are six degrees of freedom in total; NDI\u2019s solutions capture all six degrees of freedom in real-time. This type of technology, known as 3D measurement, spatial measurement, or 3D motion tracking, can be used for real-time tool tracking and navigation purposes.<\/p>

Motion Tracking in All Directions<\/h2>

3D tracking technology provides that needed detailed view by digitizing, formatting, and enabling visualization measurement data. Positional movement of the optical navigation marker or EM sensor can be tracked on the X, Y and Z axes of a 3D coordinate system. Rotation (roll, pitch and yaw) on these axes is calculated as orientation data. Movement in all directions is known, from any angle\/perspective. This movement is reported in relation to a fixed object or reference frame; i.e., a \u2018home\u2019 location. Multiple objects\u2014and their respective locations to each other\u2014can be dynamically tracked at once.<\/p>

To apply the GPS analogy to surgical navigation applications, patient imaging datasets represent the map. The target\/treatment site is the destination. And an EM sensor embedded into an OEM surgical instrument such as a catheter, or a medical instrument fitted with optical markers act as the vehicle.<\/p>

3D tracking technology can enable the position and orientation of the catheter or instrument to be known in relation to its home\/start location and destination as it\u2019s navigated through the body. The catheter or instrument\u2019s path (route) is visualized, planned, navigated, and presented in real-time to the clinician in the host OEM software interface.<\/p>

3D tracking technology bridges the gap between static patient images and dynamic instrument movements; it brings the physical world into digital interfaces. The live stream of measurement data allows instruments to be shown at the right place, at the right time. As with GPS navigation, the value of 3D tracking technology is tied to its accuracy. It\u2019s the difference between arriving exactly at your destination or being off by miles \u2013 or millimetres in surgical navigation applications.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
