When should I start thinking about incorporating
During the development stage, if possible.

Can Ascension customize a tracker to my needs?
Yes. Ascension has a long and successful record of modifying tracker configurations to meet stringent medical requirements. In 2001, Ascensi
[2009-9-27] 
Is it true that magnetic trackers are hard to use in
Yes, they can be, especially if the technology is first generation vintage. In the last 10 years many medical device manufacturers have eval
[2009-9-27] 
Are all magnetic trackers about the same?
No, there are several generations of trackers on the market. These range from 1st generation AC electromagnetic technology patented by Polhe
[2009-9-27] 
What should I look for when choosing a medical tracker?
First, seek a company that focuses on developing medical tracking products and presents a robust record of bringing products to market. Maki

What is the difference between optical and magnetic trackers?
Optical trackers operate by emitting a light source that is sensed by one of more detectors. While highly accurate, they are obtrusive and r

What¡¯s the benefit of using a magnetic tracker with an
The combination of miniaturized magnetic sensors with imaging systems lets clinicians follow a real-time graphic display of the current and
[2009-9-27] 
How are trackers used in medicine?
Motion trackers measure the position and orientation (X, Y, Z, Yaw, Pitch, Roll) of one or more sensors in 3D space. Measurements are used t
[2009-9-27] 
How can the accuracy be greater or less than the specified
Ascension specifies the tracker¡¯s accuracy using the Root-Mean-Square (RMS) error statistic. It is computed by moving the sensor to hundreds
[2009-9-27] 
What regulatory standards do 3D Guidance trackers meet?
medSAFE is a Class 1 medical device per IEC 60601-1. Its sensors are designed and tested to the Type CF, Defib Proof Applied Part designatio

How can the accuracy be greater or less than the specified
Ascension specifies the tracker¡¯s accuracy using the Root-Mean-Square (RMS) error statistic. It is computed by moving the sensor to hundreds
[2009-9-27] 
Are these variations in accuracy?
Are these variations in accuracy ¡°normal behavior¡± or is there a hardware or software problem with the magnetic tracker? You are observing n
[2009-9-27] 
Is accuracy the same throughout the tracker¡¯s motion box?
No. If, under static conditions, you move one sensor throughout the motion box (i.e., the volume in which a magnetic tracker meets its accur
[2009-9-27] 
If I need ?
If I need a firmware upgrade, must I return my tracker or insert new proms in my tracker¡¯s electronics unit? No, we can provide on-board fla

What software is provided?
You will receive a Windows API, which is compatible with APIs available for legacy trackers (pciBIRD, microBIRD and 3D Guidance) configurati
[2009-9-27] 
What is the difference between measurement rate
With previous generation trackers, there was no difference. Measurement rate was the update rate. With 3D Guidance trackers, however, a new

Is there any way to synchronize the trakSTAR with other data
Is there any way to synchronize the trakSTAR with other data acquisition equipment in our lab? In other words, can the trakSTAR accept a TTL
[2009-9-27] 
How is button status reported in the data file?
Three data formats are provided in our API that include the button status as a member of the data format structure. (See: DOUBLE_POSITION_AN
