Background: Robotic navigational platforms have seen increased interest for peripheral lung lesion biopsy due to superior stability, articulation and visualization over traditional catheters. Up until this point, incorporating tomosynthesis for real-time lesion updates required introducing other technologies into the procedure.
The Challenge: Current robotic platforms are prone to CT-to-body divergence which can lead to low diagnostic yield and require advanced supplemental imaging to overcome.
Study Purpose: This study aims to assess the tool-in-lesion accuracy of Galaxy’s TiLT Technology™ in peripheral lung nodules confirmed by CBCT.
Methods: A porcine model was used (n=4) and simulated lung nodules were placed (n=20). Each physician (n=4)
navigated with the Galaxy System™ to a lesion (avg of 5 lesions apiece), performed a TiLT sweep, adjusted the scope tip and placed the tool in the lesion. TiLT was then used to confirm the tool was in the lesion. A CBCT image was then taken, and used to confirm the tool-in-lesion accuracy for each lesion.
