Software Features

TruDi® Navigation System’s features help provide real-time visual confirmation from beginning to end:

  • Planning Points and Beacons: Planning points help identify drainage pathways, challenging anatomy and structural anomalies. Planning points also function as beacons, which alert the user when a navigated surgical device approaches the point.
  • TruView: The user can place an unlimited number of virtual cameras in areas of interest. A virtual camera provides a True View of the area, allowing the user to see beyond the endoscope.
  • Fast Anatomical Mapping (FAM): FAM is a real-time imaging tool that documents surgical changes to the anatomy.
  • TruMerge™: TruMerge™ allows automatic merging between the CT scan and an MR scan. The surgeon can control the blending level between both scans, while simultaneously navigating on both scans using the navigated tools.
  • TruPACS™: Connect to the facility’s PACS server and easily load scans directly from the network using TruPACS™.

True Reassurance

*In the preclinical study, Xoran (2020). Accuracy of Acclarent TruDi Surgical Navigation using MiniCAT 2020 and MiniCAT IQ In-Office CT White Paper, a head phantom was used to assess TruDi’s accuracy using images from the MiniCAT™ CT scanners. Target Registration Error (TRE) measurements were made by 3 testers who gathered 3 points per marker. The average of all TRE values measured was 0.34 mm.
