InnerOptic has developed a 3D visualization aid for accurate and precise targeting of hepatic tumors by ablation probes (or other needle-like instruments) under conventional ultrasound guidance.
Ablation remains a difficult procedure in part because hard because precise probe placement is crucial. If the probe is misplaced, not only is the likelihood of tumor recurrence much greater, but also healthy liver tissue could be ablated instead of timorous tissue, possibly compromising the patient’s health.
CMC Photos 12-15-2008 015.jpgThe InVision System (IVS) addresses the spatial coordination problem inherent in ultrasound-guided needle interventions, by “drawing” the needle and the ultrasound slice in the 3D positions in “real time” (above images). The surgeon can clearly see how the needle’s trajectory relates spatially to the slice, and the projected intersection point between the slice and the needle, if it is advanced forward in its current position (i.e. the pink boxes in the above images). In the left image, the yellow and blue lines indicate the angle of the needle with respect to the slice.
Further, the system can visualize an ablation volume of given dimensions, to help the surgeon determine the power settings of the ablation prior to the burn (i.e. the red and green “cage” in the right-hand image).
While the technology could be adapted into any needle-based intervention that uses ultrasound guidance, InnerOptic has initially focused on ablation (radiofrequency and microwave) of hepatocellular carcinoma.
