Fig. 5From: Matrix 3D ultrasound-assisted thyroid nodule volume estimation and radiofrequency ablation: a phantom studyAblation results using 3D matrix guidance. The dashed line indicates the ablation needle orientation. The green circle indicates an area ablated closely to the edge with minimal ablation outside the target. The blue triangle indicates the danger triangle with zero ablation outside the target. The yellow circle indicates an edge of the nodule fully ablated as well as the area outside of the nodule showing ablationBack to article page
