Fig. 2From: Evaluation of computed tomography settings in the context of visualization and discrimination of low dose injections of a novel liquid soft tissue fiducial marker in head and neck imagingScatter plot of marker volumes segmented from CT images acquired with tube voltages of 70 kV, 100 kV and 120 kV. The bold horizontal line visualizes the difference (∆) between the highest segmentable volume resulting from a 10 µl injection and the lowest segmentable volume resulting from a 30 µl injection. The yellow horizontal line visualizes the border line applied for statistical evaluation of the differentiability of 10 µl vs 30 µl markersBack to article page
