Flock of Birds Class B


Flock of Birds Class B




Ascension's new Class B Flock is a regulatory-compliant version of the popular Flock of Birds DC magnetic tracker. The tracker is housed in a metallic enclosure with appropriate modifications to fully meet IEC 60601 part 1 and part 2. Use it to track the position and orientation in real time of instruments including ultrasound probes. Tracking accuracy is unaffected by the nearby presence of conductive metals including aluminum and stainless steel.
