8. ASA (American Society of Anesthesiologists) score of ≥ 4.
9. Any other loco-regional therapies at the target lesion(s).
10. Anatomical variations in the arterial-hepatic blood supply of the liver that preclude the use of CTHA imaging.

About the study

To achieve adequate tumor treatment coverage with sufficient minimal ablation margins, several steps are required: firstly, it is critical to define tumor boundaries and extent on intra-procedural CT image; secondly, accurate planning, targeting, and confirmation of ablation probe placement within the tumor; thirdly, the use of an intra-procedural imaging assessment method to evaluate minimal ablation margins is required to define whether sufficient minimal ablation margins was obtained or if additional ablation is needed. Taking all together, those factors points to the need of having a high-precision ablation methodology for intra-procedural planning, monitoring, and ablation margin assessment. Currently, such methods are only utilized in isolation and the benefit of a combined and standardized procedure workflow is unknown. Therefore, our primary goal of this single-arm clinical trial is to investigate the technical efficacy of a high-precision liver ablation technique comprised by stereotactic-guidance, CT during hepatic arteriography-based imaging analysis, and computer-based software assessment of ablation margins for the treatment of patients referred to ablation for the treatment of primary and secondary liver cancers.
